Improvement of Certification Review Documents Process

Abstract

The purpose of this project was to improve the Certification Documents Review Process for the Certification Software Release Reports. The process performed by Pratt and Whitney’s Next Generation Product Family group is susceptible to human error and had a lead time of 210 hours. The objectives were to reduce the time required to generate the documents, the turnbacks and the delivery time. A Value Stream Mapping event was performed to design a new process that met these objectives. An action plan was developed to identify what needs to be done to accomplish the new process. With these actions, the non-value adding activities were eliminated from the process and a DXL script was used to simplify the two steps with the higher processing times. The script was used to compare the documents with the previous baseline and export the changes. The improvements of the new process resulted in a reduction of 50.71% of the lead time and a cost reduction of 32.79%.
