Analysis of E-Change Software Impact: Current Application in the Documentation Process

Abstract

The CAD/PAD Systems Engineering Department utilizes the E-Change software system in the process of routing/approving engineering change proposals (ECPs). Before the E-Change system, the Department used to process the ECPs manually which constituted a huge amount of transactions via paperwork. Therefore, to reduce the amount of paper used, streamline and automate the routing/approving process of engineering change proposals (ECPs) in the Department, the E-Change system was implemented on 04/09/2014. This Project studied the routing/approving process for the E-Change system during the period of 04/09/2014 to 04/01/2015 and compared it with the Manual method from 01/15/2014 to 03/09/2014. It was found that for the Manual method, the average routing/approving time for each ECP was approximately 60 days and for the E-Change System is currently 10 days. This demonstrates that the E-Change System is faster than the old paper-intensive process (Manual Method), as well as, featuring superior capabilities traceability-wise.
