Productivity Improvement using QMPs in a Manufacturing Unit � A case study

The Coast Guard Yard in Curtis Bay·, MD implemented a PC/AutoCAD based CAD/CAM system and used it to construct a series of 15 M (49 foot) buoy tenders. Implementing CAD/CAM is primarily a management, rather than technical, challenge. Performance-Based Management Techniques were used to develop the new system as an integrated whole, controlled and documented under ISO 9001. The process was cost-effective, required minimum retraining, was fully implemented in a few months, and was appropriate to a small shipyard building boats, but extensible as required to medium sized ships. The authors discuss:The use of Performance-Based Management and team-building techniques to help implement the process;The use of process management techniques to document, control and systematically improve the process in order to remain competitive;The process developed, including methods to allow varying levels of operator skill, geometry, weight and interference control, and development of automation techniques;The lessons learned, the results in productivity improvement, and the future path for continuous improvement

The Impact

A case study research was conducted with a view to assess the impact of five factors such as man, machine, material, money, and safety on productivity. The scope of this study was limited only to small metal workshops, which produces customized independent products. 18 case studies were performed based on selected workshops of different categories (welding shops, repair shops, sheet metal shops). Total Productivity Model (TPM) has been used as the theoretical base of the research model. It has been identified that insufficiency of skilled workers, improper utilization of materials, inefficient inventory control, ineffective safety package etc., are the most critical obstacles to productivity improvement in terms of product and material and hence to the overall productivity improvement of the organization as a whole. Some productivity improvement strategies made on the basis of the observations and analysis are also included in this paper.
