Restaurants and social media: rethinking organizational capabilities and individual competencies

Purpose – The research and practice agree that social media are reshaping strategy and organization rules across industries. Nevertheless, how social media can become a source of competitive advantage remains under-investigated and there is no evidence about which capabilities and competencies can effectively and strategically exploit social media. By merging the literature on social media management and hospitality, the authors develop and test a theoretical framework that identifies the most relevant capabilities and competencies for using social media in the food service sector. The paper aims to map them and understand which ones are relevant according to different strategic choices of social media use. Design/methodology/approach – The authors adopted a qualitative methodology using semistructured interviews tomanagers or owners of 14 restaurants in a big city in Northern Italy. Findings – The theoretical framework suggests that social media could be strategically used for different aims by relying on specific capabilities and competencies. The authors tested it and found that, though nowadays restaurant managers mainly focus on a narrow set of social media competencies linked to relational and marketing capabilities, some also rely on social media to promote organizational change and innovation. Originality/value – The authors propose a theoretical framework and preliminary evidence on capabilities and competencies declined for the food service sector. The model considers different uses of social media and related capabilities and competencies by mapping them accordingly to their strategic use. The authors preliminarily validate our framework and highlight the competencies possessed by the restaurant managers of our sample and their alignment with the strategic use of social media.

Introduction "Jamie's Italian" franchise restaurants are facing collapse. Marina O'Loughlin's review of one "Jamie's Italian" restaurant in the Sunday Times was merciless and eight months after, the celebrity chef's eponymous chain went into administration, putting 1,000 jobs at risk. The reasons were many, but one of the most relevant was the bad reviews that "Jaime's Italian" received on online platforms [1].
Such as in the tourism sector, in the food service social media (henceforth SM) technology has resulted in the arise and growth of a myriad of online platforms that share diners' experiences (Munar, 2012). As a result of SM platforms, consumers can now digitalize their experience, with comments or photos and publish them on the web, sharing them with thousands of people around the world. What used to be personal storytelling and word-ofmouth (WOM) communication about restaurant experience has now been transformed into a potentially global e-WOM (Dellarocas, 2003), thus exponentially increasing the competition for very small restaurants too. Furthermore, these platforms are nowadays highly widespread and the surge of food bloggers and influencers is now a growing trend that further increases the popularity of SM platforms in the food sector (Munar, 2012). Today's complex restaurant environments (because of a multitude of intermediaries, i.e. SM platforms), the extensive competition that not only big restaurant chains but also small restaurants must face and the sharing of food opinions and photos in a constant co-creation process, have made the food service sector particularly challenging. Consequently, restaurants managers now need to rethink their organizational capabilities, competencies and strategic use of SM (Tussyadiah and Fesenmaier, 2009).
Despite the relevance of SM, organizations still do not fully profit from them. This is mainly due to the lack of resources (e.g. time) and necessary capabilities and competencies to effectively use different SM platforms accordingly with the organizational aims and keep up with their constant transformation (Roy and Dionne, 2016). Investigating the gap of capabilities and competencies needed to properly manage SM in the food and beverage sector can be a relevant topic both for academics and practitioners. Indeed, despite the increasing diffusion of SM, managers are still uncertain about how to best exploit them according to their main strategy, thus using them as a source of competitive advantage (Macnamara and Zerfass, 2012).
So far, the hospitality literature has mainly focused on the prosumers' (producer and consumers) use of SM and the reputation spread through them, the comparison among different SM platforms and how and why organizations use SM for marketing or communication (Xiang et al., 2017). However, a savvy and competent use of these platforms and the recognition of those organizational capabilities that are central to the exploitation of SM as a strategic tool could generate value and competitive advantage for hospitality organizations. Furthermore, previous research mainly focused on the use of SM in the tourism sector, while the food and beverage one is still insufficiently investigated (Fox and Longart, 2016). We can assume that there are specific capabilities and competencies strictly inherent to the food and beverage sector, as the products, time management and widespread evaluations are somehow different from hôtellerie. To identify them, we propose to merge the capabilities and competencies of the food and beverage sector with the SM ones.
Our research questions are therefore the following: Q1. Which capabilities and competencies are needed to exploit SM in the food and beverage service sector?
Q2. Which capabilities and competencies support different strategic uses of SM?
To answer our research questions, we develop a theoretical framework that shows the possible different strategies of SM use. Each of them requests a specific set of capabilities and competencies.
To provide a first validation of our framework, we performed an exploratory empirical study that involved owners and managers of 14 restaurants. Through semi-structured interviews, we analyzed individual competencies that interviewees declared and perceived as relevant for the strategic use of SM. As we rely on micro and small enterprises, where the restaurant's owner and their few employees are the "core" of the firm, those individual competencies can be transferred to a higher level of investigation, i.e. the organizational level. Organizational competencies are comprised among the components of organizational capabilities (Zehir et al., 2006). In the present work, we attempt to draft a more comprehensive map of the useful capabilities and competencies that restaurant managers need to fulfill their strategic use of SM.
The concept of "capability" refers to the organizational level and is more comprehensive than "competence", as, besides the latter, it includes strategy orientation and the connection between resources and skills (Zehir et al., 2006). Capabilities can be classified in ordinary or "zero-level" capabilitiesthose that permit a firm to "make a living" in the short termand dynamic capabilities, i.e. those that operate to extend, change or create ordinary capabilities (Barreto, 2010). A "dynamic capability" is "the firm's ability to integrate, build, and reconfigure internal and external competencies to address rapidly changing environments" (Teece, Pisano and Shuen, 1997, p. 516). It is "the capacity of an organization to purposefully create, extend or modify its resource base" (Helfat et al., 2007, p. 1). Organizations can thus rely both on ordinary and dynamic capabilities and the related resources, skills and competencies as a source of competitive advantage. Nevertheless, they should carefully choose and implement those capabilities that are the most relevant for their strategic purpose and learn to reconfigure existent capabilities to deal with changes (King et al., 2001;Teece, 2007).
Nowadays, in the digital economy, firms conceive their role less within industries and more within business ecosystems, where organizations and customers work together to create and sustain markets and products (Teece, 2017). Digital platforms, which include SM, are tools that enable the development of digital ecosystems where organizations, users and firms' stakeholders virtually meet, influence each other and co-evolve. Consequently, the evolution of the organization's capabilities is necessary to manage their digital ecosystem and to effectively exploit SM platforms. Such a change of contextual conditions surrounding companies entails the revision of the organization's ordinary and dynamic capabilities. In particular, dynamic capabilities are relevant for managing platforms and their associated ecosystems because they may help in anticipating changes and adjusting business models (Teece, 2017).
To our knowledge, it is not clear, which capabilities, both ordinary and dynamic, are the most useful for the full exploitation of SM platforms according to their strategic role for the organization strategy. For the present study, we resort to research that considers some capabilities as appropriate for the effective use of SM platforms. However, to our knowledge, there is no study that organically maps all the capabilities useful for a strategic use of SM, especially in the food and beverage sector. Furthermore, as capabilities include individual competencies, resources, practices, strategy orientation and the ability to exploit competencies and resources to accomplish goals (Aral and Weill, 2007;Zehir et al., 2006), we rely on the few studies about individual competencies to manage SM to understand how these can be used to build capabilities and thus, obtain a competitive advantage in the digital ecosystem.
Therefore, to develop ordinary and dynamic capabilities it is important to develop employees' competencies. Following the theory and coherently with the goal of this study, we focus not only on capabilities but also on the workers' specific competencies in the efficient use of SM. Table 1 is a summary of the capabilities and the related individual competencies that the literature highlights as the most relevant to SM as strategic tools.
Among digital capabilities, the ownership, protection and utilization of technological assets are key differentiators among firms and a source of competitive advantage (Teece et al., 1997). Key digital capabilities in SM management (henceforth SMM) are related to three main areas, namely: 1. search engine optimization (SEO) activities, that is, the process of increasing the quality and quantity of website traffic and visibility in a search engine (Baye et al., 2016); 2. big data analytics, requiring IT-specialists, e.g. big data specialists and data scientists (Gandomi and Haider, 2015); and 3. SM features. Regarding the latter, a savvy use of SM platforms can be a key differentiator, but managers should be aware that SM platforms are not a unique entity.
On the contrary, they differ in features and potentialities (Dossena, 2012), for example, forums enable a more bi-directional communication than social bookmarking platforms. Therefore, firms should develop online social networking skills specific for the digital platform in use. Online social network skills consist in: understanding the technological properties that specifically enable social interactions; and knowing the practices that increase interactivity (Hsieh, 2012).
Several authors highlight the relevance of having adequate relational capabilities and communication and listening competencies such as the ability to create buzz through viral messages, for example, with short lists of very popular topics (Kirby and Marsden, 2006). In literature, listening competencies are mainly explored in two research fields. One strand focuses on competencies and personality traits describing a good listener; Maben and Gearhart (2018) concentrate on empathic listening behaviors (Bodie, 2011) such as giving pertinent responses, elaboration, offering advise and opinions and answering/asking questions. On the other hand, IS literature explores the IT tools that support web monitoring (Francesconi and Dossena, 2012).
SM are also frequently related to marketing purposes (Felix et al., 2017). Marketing capability is defined as the "integrative process designed to apply the collective knowledge, skills and resources of the firm to the market-related needs of the business, enabling the business to add value to its goods and services and meet competitive demands" (Zehir et al., 2006, p. 111). Among others, competencies in search engine marketing (SEM) are particularly useful (Dou et al., 2010). SEM is a form of online marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) primarily through paid advertising. Other useful competencies are related to communication and modelling/analysis activities. Communication competencies are particularly useful for the customer relationship management (McGowan et al., 2001). The modelling/analysis competencies are related to the ability to interpret data shared within online communities for strategic marketing management (Cravens and Piercy, 2006).
Upper management capability refers to strategic decision-making, i.e. defining the major strategic moves of a firm (Zehir et al., 2006). It relies on leadership and on competencies such as the ability to manage uncertainty, flexibility, adaptability, problem-solving and open-mindedness (Evans, 1991). Among management capabilities, project management capabilities are mostly related to event management, teamwork and collaboration skills (Tench and Moreno, 2015). Online reputation management, which requires adequate competencies in crisis management and reputational risk management (Berthon et al., 2012), is another critical issue (Dijkmans et al., 2015). Indeed, the internet facilitates the virulent diffusion of negative comments and opinions about a firm's reputation (Wiedmann et al., 2007).
Regarding the strategic area, the literature mainly focuses on the integration and exploitation of SM for gaining a competitive advantage. Critical thinking or its related conceptsi.e. problem-solving, analysis skills and strategic thinkingare crucial for strategic SMM (McCleneghan, 2006). Modelling/analysis competencies and critical thinking are also pivotal for the integration of knowledge shared within a social community in business processes, as they enable organizations to understand and interpret trends and link them to business (Tench and Moreno, 2015;D'Angelo, 2010). On the one hand, these analytic capabilities require creativity, intellectual curiosity, flexibility, adaptability and an open mind to interpret trends in an original and unexpected way (exploration activities). On the other, a deep understanding of the business, methodological rigor and attention to details are needed to efficiently exploit the new knowledge for improving strategy, products/ services and processes.
To reach a competitive advantage, organizations also need innovation capabilities. Product/ service capabilities emerge from different functions, resources, skills and expertize of the firm. The ability to rapidly develop and introduce new products and services is a source of competitive advantage (Zehir et al., 2006). In this sense, SM enable the monitoring of competitors' products and services, as well as customers' needs (He et al., 2013), thus becoming a useful tool to support innovation capabilities. Knowledge exploration and exploitation, innovativeness and absorptive capacity (Cohen and Levinthal, 1990) are core competencies related to innovation capability, as suggested in the literature on open innovation and crowdsourcing (Ooms et al., 2015). Indeed, in open innovation and crowdsourcing activities firms exploit shared knowledge and online communities to improve their innovation capabilities (Svetlik et al., 2007). However, to efficiently exploit knowledge sharing firms should develop suitable levels of absorptive capacity, as described in the previous paragraph. Many authors explore the processes and mechanisms behind social and cooperative learning within an online community and the related issues of knowledge collaboration and co-creation (Faraj, Jarvenpaa and Majchrzak, 2011).
When firms are able to constantly change their resource-base through the exploitation of the digital ecosystem, they own dynamic capabilities (Teece, 2017) directed at effectively manage SM platforms. The strategic use of SM may lead to the anticipation, recognition of changes, creation, acquirement and sharing of knowledge to respond to opportunities and threats arising and spreading on the SM and may finally enable the adjustment of the business model and the reconfiguration and integration of current capabilities.

Capabilities and competencies in the hospitality sector: a framework proposal
In the hospitality context, research aimed at identifying the relevant capabilities and competencies started during the 1990s and adopted different frameworks (Sandwith's, (1993), competency-domain model). However, studies about the relevant capabilities that the hospitality firms, especially restaurants, can use to effectively exploit SM as a tool for competitive advantage are scarce and not systematized. Ayeh et al. (2012) explored Hong Kong practitioners' perceptions of SM in the tourism industry concluding that organizations apply a variety of strategies in day-to-day management, namely, they use a range of SM platforms to maintain high exposure toward potential and existing customers, they continuously update the company's account to ideally raise the users' interest, they assign a staff member to deal with enquiries and comments and they post good reviews to maintain a positive image and online reputation. However, the capabilities, competencies and personal attributes, which are useful for the adoption of an informed specific strategy in managing SM remain unclear.
Therefore, we review research about SM use in the hospitality sector and the associated capabilities and propose a framework that can contribute to systematize the relevant capabilities for a strategic use of SM (Figure 1).
In our framework, we consider two main dimensions, namely, the first is the SM focus, which can be mainly internali.e. to fulfil internal purposes such as exploiting customers' suggestions for improving the restaurant offer or e-recruiting processesor external such as spreading a culinary culture on a new cooking technique (e.g. molecular gastronomy). The second dimension refers to how central SM are in restaurant strategy. The alternatives for this dimension are, therefore, either high, if the restaurant strategy and source of competitive advantage rely on SM or low, if the restaurant owners consider SM a complementary asset. Four combinations stem from the intersection of these two dimensions.
The first combination, labeled "showcase", refers to restaurants using SM with an external focus and as a tool with low strategic importance for the firm's competitive advantage. In the literature, authors explore the use of SM especially for customer-relations and for marketing purposes (Baird and Parasnis, 2011). Supplier-related studies in the tourism and hospitality sectors (Schmallegger and Carson, 2008) have closely concentrated on the role of SM in supporting marketing capabilitiesespecially promotion (Leung et al., 2011) and communication capabilities, both internal and external to the organizational boundaries (Pantelidis, 2010). Hence, in this category, the capabilities used, besides the technological ones, are those related to communication and marketing.
The second combination, labeled "spy-hole", refers to restaurants that mainly adopt a passive role in SM use. By analyzing comments on online communities such as TripAdvisor, organizations can better understand what their guests like and dislike about them and their competitors besides monitoring the competitors' strategy and behavior. In this case, SM are relegated to a monitoring role and used as a benchmarking tool. SM are not a source of competitive advantage and the focus is internal, as companies acquire information to gain insights into how they could improve their business by also taking into consideration the competitors' strategy. Although the literature does not specify the most relevant capabilities involved, we could hypothesize that strategic capabilities are needed to enable organizations to understand and interpret trends and link them to their business (Tench and Moreno, 2015;D'Angelo, 2010). In this case, web monitoring and analysis/synthesis competencies are pivotal, as a fast identification of the most significant information among the vast amount of web contents is important (Francesconi and Dossena, 2015).
In the third combination, labeled "glue", restaurants use SM with an external focus, but their relevance for the firm success is very high. When firms recognize the digital ecosystem as crucial for their success, they spend a lot of time and resources (i.e. dedicated people) in creating and managing long-term relationships with their "digital stakeholders". In this case, the restaurants use SM to create a strong online community around the firm or around a topic (e.g. a specific type of cooking, a regional cuisine, etc.). The upper management capability and strategic capabilitiesand the related competences (especially leadership, critical thinking and time management)seem useful to exploit SM as a tool to engage current and potential customers, suppliers and competitors. Therefore, relational capabilities are essential too. Restaurants should also take care of adequate individual characteristicsi.e. ethics and integrity, tolerance for change and openness to new ideasrelated to these capabilities (Chung-Herrera et al., 2003;Suh et al., 2012).
Finally, in the fourth combination, SM are used as a strategic "engine", as organizations analyze information and exploit shared knowledge across different online communities, internalize it and consistently organize and improve their internal processes or create new products/services. As SM effect changes in the creation process of online contentfrom organization controlled content to content, which is an expression of the users' interaction and participation (Munar, 2012) they can be used as knowledge sharing tools allowing for the combination of internal capabilities (i.e. those possessed by the firm) with external ones.
In particular, socialization through SM can facilitate the exchange of tacit knowledge through joint activities, namely, exchanging thoughts, brainstorming and sharing experiences. Socialization takes advantage of customers and suppliers' tacit knowledge. Through internalization, explicit and tacit external knowledge is shared throughout the organization and converted into or combined with internal tacit knowledge (Nonaka et al., 2000). Shamim et al. (2017) emphasized the usefulness of SM platforms for knowledge sharing (both internal and external) and they highlighted other core capabilities needed to effectively exploit SM as a strategic "engine". These are knowledge-oriented leadership, innovation capability, ability to share information. To enhance the process of knowledge sharing and innovation capability, hospitality firms need to use SM to convert the tacit knowledge of employees into organizational knowledge by transferring it into the organizational memory (Shamim et al., 2017) and to internalize external knowledge within organizations. Crowdsourcing is a good example of how firms can gain advantage from the knowledge shared within an online community to nourish and strengthen their innovation capabilities (Feller et al., 2012). When innovation and constant change are at the core of competitive advantage, firms can also develop dynamic capabilities. In this case, SM become relevant tools to obtain a competitive advantage as they can help to constantly change the business and effectively take advantage of both internal and external resources. The use of dynamic capabilities can support organizations in exploiting SM to notice changes, share, acquire and create knowledge by combining organizational and users' knowledge, by integrating and reconfiguring resources to exploit market-based opportunities or overcome possible threats (Teece, 2007).

Methodology
We adopted an exploratory research approach consistent with a qualitative method (Trauth, 2001). The interpretative qualitative method was used because of its strengths in providing insights into individual experiences and life settings (Walsham, 2006). In particular, a case study research strategy was used (Yin, 2017) and was motivated by the aim to increase the empirical knowledge on capabilities, competencies and individual characteristics needed for SMM in the food service sector. The empirical investigation took place in 14 restaurants in Milan, one of the most. well-known Northern Italian cities in the key tourism generating markets (De Carlo et al., 2009). In Italy, most of the food service sector businesses are SMEs. Therefore, a sample of SMEs was recruited to investigate whether and how they approach SM (Table 2). We sent an invitation to the interview to 57 restaurants, which had agreed to participate in a previous research on their customers' habits in using SM for choosing a restaurant. Among these, 57, 14 accepted to take part to the interview. Even though this auto-selection may generate biases, we believe this sample can be useful for our research aims. As we were interested in understanding the relevant organizational capabilities and individual competencies used or perceived as useful to manage SM, it was consistent to involve a sample of restaurant managers and owners who use SM for their business, albeit with different strategies. Hence, we focus only on restaurants that are interested in SM use for their business activity.
All the restaurants are in the same geographical area and are, thus, comparable in terms of customers, location and expenses. By analyzing ex post the SM pages of these restaurants (i.e. TripAdvisor, Google rating, Facebook, Just Eat, Deliveroo), we found that all the 14 were sufficiently active onlinewith an institutional account on at least three different digital platformsand sufficiently successful in terms of online reputation [with feedback ratings higher than 4 (out of 5) on Google Ratings, Facebook, Tripadvisor, Just Eat and Deliveroo and higher than 8 (out of 10) on TheFork].
The main data sources are semi-structured interviews. All interviews took place face-to-face and were performed from April to May 2019. The interviews were digitally recorded and fully transcribed. We interviewed one person for each restaurant, either the owner or the restaurant manager who, etc, are in charge of managing the restaurant SM pages. Table 2 shows information about each restaurant (type of cuisine, average cost, number of employees, main SM used) and data about the interviewees (role, age, gender). The average age of the interviewees is 45, with a minimum of 30 and a maximum of 66.
The interviews lasted between 12 and 28 min. Respondents were asked about their familiarity with SM platforms, their use of SM, the competencies that they think allow them to best exploit SM and changes in their SM activity. These questions allowed us to understand their perceptions about SM and the capabilities and individual competencies that they value the most, by interpreting both what they explicitly declared and implicitly revealed when answering questions not strictly related to SM capabilities.
To analyze the semi-structured interviews, we adopted Gioia's methodology to assess qualitative rigor (Gioia et al., 2013) and to aggregate the concepts in macro themes and dimensions. In addition, we performed a frequency analysis of the first-order concepts to understand, which competencies are perceived as relevant according to the different SM strategic use. Table 3 illustrates the systematization of the interviews by showing the capabilities and competencies the interviewees revealed as fundamental in effectively exploiting SM for their business. We unified the capabilities, which emerged from the interviews in seven aggregate dimensions corresponding to the main capabilities found in the literature (Table 1). Furthermore, Table 3 shows the frequency analysis of the first-order concepts, thus identifying which capabilities and competencies are perceived as the most relevant to be a successful restaurant.

Technological/digital capabilities
All the restaurant managers and owners acknowledged technological/digital capabilities, at least at a basic level, as necessary to use SM effectively. Interviewees highlighted the need to have basic knowledge about the functionalities of different SM platforms and were aware j JOURNAL OF TOURISM FUTURES j  Open mind and flexibility to manage SM and to promote their use among employees 2 Appropriately and politely answer to negative comments Online reputation management 11 Ability to detect and reveal fake reviews obtaining competitive advantage

Relational capabilities
Respondents considered communication as a core competency, in particular they focused on language coherency and message efficacy.
Language coherency refers to the attention paid to the use of different communication styles according to the SM platform, the content of the message and the customers who will read it. For example, the use of LinkedIn is associated with formal communication, as it mainly reaches professionals, while Facebook is used for more informal communication, e. g. to promote new menus or deals. Different SM and language styles involve different jokes, slogans and photos. It also depends on the type of restaurant, namely, an elegant restaurant usually adopts a more formal type of communication than a fast-food one.
There are different ways to communicate. When you use Instagram stories you have to adopt a more relaxed and informal type of communication, when you use LinkedIn posts you have to use a more formal language. The language style impact the strength and appropriateness of the message (Beta).
Restaurant managers are aware that coherent information needs to be published on their SM pages. However, sometimes they struggle to achieve information consistency.
One of the first things to do is update all the SM platforms, and be coherent with the information given (Theta).
Respondents also mentioned the ideal characteristics of effective messages, namely, clarity, linearity, sincerity and transparency, charisma and surprise. Moreover, the message must contain valuable information.
It is better to write truthful messages, to show transparency and avoid possible critics (U).
Furthermore, listening capabilities were also relevant for the interviewees, in particular, monitoring SM pages can improve the understanding of customers and suppliers' needs and increase the ability to respond consistently. Ability to imitate and copy the social media strategies the best restaurants are implementing Implementation of best practices 6 Attentiveness to food and service quality because of comments and pictures Food and service quality and creativity 2 Effort to obtain the "aha effect" and surprise 4 Effort to realize visually creative plates 2 Redesign processes by looking at reviews and comments Organizational change Dynamic capabilities 2 Managing internal interdependencies Lastly, some restaurant managers highlighted the need of good storytelling about the restaurant and its activity, not only to improve the informational communication but also the emotional one.
Communication does not mean only giving useful information, but also relying on emotions to increase our relationship with customers. We need to be able to tell a good story about our restaurant and what we do every day (Alpha).

Marketing and customer relationship management capabilities
Most of the respondents stressed the importance of having adequate marketing and customers relationship management (CRM) capabilities. Some restaurant managers rely on external SM managers or a SM agency for marketing purposes, while others internalize the SMM activities. Even though the strategies (internalization and externalization) are alternatives all restaurants managers agreed on the relevance of these capabilities. Some of them argued that, given the relevance of SMM activities, they prefer to manage them personally; others, on the contrary, admitted to relying on professional partners, as they do not possess the adequate marketing and CRM capabilities. Additionally, few restaurants also use CRM tools. The majority of restaurants are aware of the necessity to segment customers and use SM in a different way accordingly.
Furthermore, few of them recognized the need to have diplomatic and negotiation abilities to better manage customer-related issues and requests.
You have to learn how to deal with customers in a diplomatic way so not lose customers or potential customers who can decide to avoid your restaurant based on your disrespectful behavior and online communication (Eta).

Upper management capabilities
Our sample identified online reputation management as a core-competency to resolve conflicts smoothly, detect fake comments and reviews, provide polite answers to discrediting fake reviews, thus, obtaining visibility and competitive advantage.
It is important to recognize fake reviews. They are usually very general or they report facts that we do not remember or meals that we do not have on the menu. Then, it is important to answer and demonstrate that those reviews are unreliable (Alpha).
Some of the interviewees were also aware that there are tricks related to time management that can increase the visibility of posts. One is, for example, posting at a specific time or carefully plan the frequency of a new post.
Time scheduling of posts on SM is something that you have to plan in advance if you want to use them effectively (Heta).
To engage potential customers, it is essential to know the restaurant's distinctive strengths and how to promote them. Consequently, managers need to build a strong brand identity so that customers can easily recognize it. This also helps them to engage and retain employees and strengthen inclusion in the organizational culture. Building and spreading a strong brand identity, coherent among different SM, is a way to use SM as relevant and strategic tools for restaurants.
It is essential to be aware about the restaurant's strengths (e.g. appealing location, particular food.) and be able to show and communicate them to the customers (Beta).
We have built a strong brand identity and we are aware of the importance of communicating it outside the restaurant and sharing it with the customers. However, it is also important to constantly re-state it within our team (Mi).
Lastly, leadership is perceived as fundamental to the promotion of SM strategic use, as a leader should promote a culture that is open and flexible to the use of new technologies, allowing employees to use and experiment with SM and considering platforms as a possible source of competitive advantage and not as a mandatory requirement.
SM should not be seen as something that we have to use because everyone does and we have to keep up with our competitors, we -as restaurant managers-have the power to change these narrow-minded visions and promote the use of SM as a strategic tool for the entire organization (Kappa).

Business and strategic capabilities
SM can be used strategically to improve the business by interpreting new trends concerning food, service and location displayed by competitors or customers and by adapting to them. Moreover, SM provide comments and reviews for internal purposes, which are useful to improve competencies such as product developments. Thus, SM are considered a source of knowledge and are used to integrate this new knowledge into the restaurant's knowledge-base.
By carefully reading comments and reviews, we are able to understand our weaknesses and improve the quality of our products and service. Customers are now experts about restaurants because they use them more frequently and they follow famous chef TV shows, so they can have a competent discussion and share knowledge (Ni).

Innovation capabilities
In a constantly changing environment where customers' needs and desires change rapidly, also at the pace of "haute cuisine" TV shows, the ability to offer a constantly updated service is perceived as really significant, especially in the competitive area of Milan. The high level of competition among restaurants on SM leads some of them to improve their plating aesthetic while pushing their creative content. However, competitors could also be an inspiring source of knowledge and innovative outcomes. Notably, one manager stressed the importance of using SM to understand who the best players on the market are so that they can internalize, imitate and be inspired by them. Attention to food creativity, service, location and constant plates innovation are promoted by a savvy use of SM.
I only need to recognize the other restaurants' best practices in dealing with SM effectively. Once I have identified them, I simply try to replicate them in my restaurant (Beta).

Dynamic capabilities
SM could be used to manage restaurants and promote constant organizational change too, as they become useful sources of information for knowledge exploration and exploitation (Francesconi et al., 2013). Restaurants with a high absorptive capacity efficiently explore and exploit knowledge shared on SM. This occurs when they acquire, recognize and assimilate valuable reviews that are then used ad transformed to improve their offer. In accordance with this perspective, some managers considered SM as useful tools to acquire new knowledge that, combined with the internal one, promotes organizational change and redesigns internal processes. Customers' comments and reviews reflect the customers' evaluation and suggestions, which can be internalized to promote constructive changes in organizing activities and managing team interdependencies.
I review the comments posted on SM platforms with the staff in order to understand what went wrong and if we can change something in our way of working or in the product to meet higher standards (Kappa).
Our results confirmed the main capabilities in SMM predicted in the literature. Nevertheless, the main related competencies do not align: Table 4 compares the competencies in the literature with our results.
Most of the competencies reported in the literature are also cited by respondents as crucial for SMM activities. However, restaurants managers do not perceive modelling/ analysis competencies, strategic decision-making ability and critical thinking as particularly relevant.
The results do not provide new competencies as crucial for SMM activities. Table 5 presents the positioning of the restaurants involved in our qualitative study within the theoretical framework we have hypothesized. We positioned every restaurant following their strategic use of SM platforms and the competencies involved as it emerged from the semi-structured interviews.
It is worth noting that the four combinations in our framework can coexist, i.e. a restaurant can concurrently pursue different strategies and, therefore, develop capabilities and competencies that are related to two or more combinations of our framework. A restaurant could simultaneously use some SM for their internal focuse.g. using LinkedIn for recruitingand other SM for their mainly external focuse.g. using Facebook for benchmarking activities. A restaurant can both attribute a low level of importance to some SMe.g. a restaurant can perceive the website as a simple way for customers to reach itand assign a strategic role to otherse.g. the restaurant's forum can be a useful way to engage customers and opinion leaders. All the restaurants use SM platforms as a "showcase", as they are essentially considered as communication and marketing tools that help them promote the restaurant and give information to the customers. Therefore, restaurants mainly rely on relational and marketing capabilities and customer relationship management ones. The interviewees focused on language coherency, message efficacy and web monitoring. In this case, SM are considered as complementary assets that help increase the business visibility to the external environment.
SM platforms are also used as "Glue" tools by most of the restaurants. These restaurants, in particular, use negotiation and leadership competencies and the ability to manage conflicts when dealing with negative or fake reviews. Furthermore, SM allow them to promote honesty and transparency in their organizational environment. They also use SM to externally promote engagement (e.g. with online initiatives such as 'photo contests') by developing a strong brand identity.
Only few restaurants also considered SM as a valuable tool to monitor customers, suppliers or competitors' behaviors, thus exploiting SM as a "spy-hole". Such information could enable the organization to evolve, but, at the moment, the restaurants in our sample seemed to remain more passive in the monitoring function, thus not fully exploiting SM, as they do not act upon the collected suggestions. In this case, SM maintain a low level of importance, although the focus is internal. Relational capabilities are perceived as essential in this combination. Only few restaurants perceive web monitoring as a critical issue.
Lastly, there are few interviewees that use SM as an "Engine" to promote organizational change and improvement. For instance, by examining comments and posts, managers can review, which work processes failed and redesign them. These restaurants evaluate suggestions and knowledge shared by the customers with the aim of internalizing them thus innovating and proposing more creative dishes and services. Lastly, they are able to recognize the best practices in using SM and effectively adopt them and exploit them.
Only one restaurant in our sample fully exploits SM by using them in all their possible functions. The SM's potential has thus not been fully discovered by restaurant owners and managers yet, but there are signs of improvement (four restaurants use SM in at least three ways, namely, showcase, spyhole and glue).

Conclusions
Our study has both theoretical and managerial implications. By merging the literature on SMM and on the hospitality industry, we developed and preliminary tested a theoretical Table 5 The positioning of the restaurants in the framework Showcase Spy-hole Glue Engine framework aimed at identifying the relevant capabilities and related competencies for the successful use of SM according to restaurants' strategic purposes. Our framework could both enrich the literature on the SM capabilities and competencies in the food service sector, which have not been sufficiently investigated and answer the call for more evidence on how to manage communication within SM in this sector (Fox and Longart, 2016). Indeed, the framework identifies the most relevant capabilities and related competencies for successfully dealing with SM in the food and beverage service sector, thus enriching both the SM and hospitality literature. From a managerial perspective, we aim to give restaurant managers and owners some useful suggestions about which capabilities and competencies they should develop according to the strategic purpose they attribute to SM. Integrating all the approaches to SMshowcase, glue, spy-hole and enginemeans exploiting the full potentialities of these platforms. new can assume that not all the restaurants can invest in all the SM functions. However, we believe that restaurants could benefit from pursuing consistency among the capabilities and competencies they have, the importance they give to SM and the main strategic focus they pursue.
Finally, our study offers a contribution through the comparison between the main competencies found in the literature and the competencies that restaurant managers perceive as useful.
Although the present study proposes a systematization of competencies and capabilities, which are useful to exploit the SM potential in accordance with different strategic priorities, it is nevertheless exploratory and it involves a small number of restaurants, which does not allow for generalizability. Furthermore, the sample is composed of people who gave permission to be interviewed, so there is a high chance of auto-selection biases. Thus, our results are limited to a restricted number of restaurants that seem to be interested in the use of SM for business purposes and in acquiring more competencies to fully exploit them. This allowed us to involve respondents who have some degree of "digital capabilities" and can exploit capabilities and competencies to manage SM. Restaurants in the sample are also located in the same Italian city. This enabled a comparison, but future research should include restaurants from other locations. Finally, we have derived capabilities from the analysis of main related competencies. We are aware that besides competencies there are other elements (i.e. strategy orientation and the connection between resources and skills) that are essential ingredients for obtaining capabilities. Hence, future research could hopefully include these elements to draw more comprehensive evidence on how restaurants can develop capabilities to exploit SM successfully. Finally, we plan to investigate in future studies, which capabilities and competencies can be outsourced, also according to their strategic relevance for SM.
