Business processes and production processes are complex inside the aerospace manufacturing industry. Quality, cost, delivery and flexibility are the fundamental requirements of aerospace manufacturing suppliers. The aerospace manufacturing suppliers have to coordinate those fundamental requirements and integrate the business and production processes in the competitive market. This study applies the concepts of reengineering, and allies the functional groups and system resources inside the aerospace manufacturing suppliers. The effective business and production processes are then developed so that the business and production activities can benefit the enterprise. Thereby, the aerospace manufacturing suppliers can strengthen their competitiveness in a dynamic aerospace market.
