Study On EXPRESS Product Development Process Optimization Based On ACE

ACE(Achieving Competitive Excellence for Competitive Advantage)is a quality management system developed by UTC(United Technologies Corporation of America)based on lean production,which can ensure that UTC is always ahead of other competitors when changing.Customer first,attention process,based on data,and continued to pursuit of results.EXPRESS Elevator is a wholly-owned subsidiary of OTIS based on the strategy of multibrand in China,which is owned by UTC.It focuses on the middle and low-end market.Currently,due to the lack of growth and the continuous influx of elevator enterprises,the competition is unprecedented fierce.EXPRESS elevator has exposed many problems in product development cycle,customer complaint feedback solution,product quality and cost control.It is necessary to optimize the core process to eliminate these problems.This paper mainly relies on the theoretical knowledge of process,and process optimization,process reengineering and process management are the main steps of the process change of EXPRESS Elevator product development.We use the principle of lean production in the process,and use QCPC/VSM/RRCA of ACE tools to optimize the key points.This paper bases on the product development process of EXPRESS Elevator,and identifies the main problems of customer feedback in which links of the process.The five main processes of cost optimization,product change,escape solution,mechanical design and electrical design are identified.With the help of ACE quality management system tools,we can eliminate or improve the non-value-added links in the process by adding or unifying standard job templates,defining clearly input/output,updating or publishing program documents,adding audit nodes and updating flow charts to achieve the goal of solving the above problems.At the same time,the renewal process is only the beginning.The long-term guarantee is to further strengthen the management means such as maintaining full communication,compiling process guidance chart,defining the responsible person,performance appraisal and ACE certification.
