The role of Industrial Engineering Department (IED) is very crucial in improvement of factory performance. The involvement of Industrial Engineers (IE) starts from sampling stage through product analysis to ensure the sample sent for approval is most suited for bulk production. The IED forms the backbone of the entire factory operations by setting production targets and defining methods that need to be followed in the shop floor. The responsibility of IED is to maximize overall efficiency of the manufacturing functions through provision of an effective, appropriate and timely work study and Industrial Engineering service and maintenance of an ideal production environment. The key tasks includes product analysis through determining optimum method of construction and establishing Operation Bulletin (OB); product costing by determining standard minute cost of each operation specifying the equipment type and work aids used; production planning for effective and balanced flow of product; operator performance monitoring systems by hourly production monitoring and skill matrix; off-standards of different functions and implement methods to reduce; method; justify all changes based on analysis of work content; continuous improvement; taking cost saving opportunities; monitor operator performances and take action to improve performances and eliminate causes of underperformance.
