Warehouse server productivity analysis with objective matrix (OMAX) method in passenger boarding bridge enterprise

One of the leading keys to successful management in Inventory Management is Human Resource. Its productivity directly improved the production process performance. This research objective is to analyze warehouse server productivity by incorporating Objective Matrix Method (OMAX). Three criteria are observed, they are Service Time, Database Input Time, and total output. The observation was conducted in 5 days. The object in this research is server at two warehouses in a passenger boarding bridge enterprise. First worker productivity is increase for 4 days with average Index Performance 141,67% and decrease in one day with index performance 33,33%. Meanwhile, second worker productivity is decrease for 4 days with average index performance 70,84% and increase in one day with index performance 33,33%. Productivity between one server with others were unequal. Based on the difference, furthermore analysis is done by using cause-effect diagram (fishbone) to determine the root of the problem stated. The cause of the problem is each server has difference technical ability, there is no Standard Operating Procedure for warehouse service and database input process, the warehouse layout and the working environment is not practicing proper 5S (sort, set in order, shine, standardize, sustain).
