Information : Electronic Change Control
Electronic Change Control (ECC) is part of the enabling technology support systems for Concurrent Engineering (Integrated Product Development [IPD]) at McDonnell Douglas Aerospace (MDA). ECC is an on-line system accessible throughout MDA for tracking and controlling engineering changes. The system supports parallel activities and simultaneous multiple users within the change control process. ECC exemplifies MDA's commitment to Concurrent Engineering (IPD) and its dedication to maintain a leadership role in the aerospace industry.
A major advantage of the integrated ECC system is the ability for drawings developed on Unigraphics workstations to be displayed on desktop computers. The ECC system user friendliness is provided through a variety of hierarchical menus that allow functionalities such as:
Entering and viewing drawing changes; Establishing and displaying review lists;
Notifying reviewers via electronic mail;
Providing password schemes;
Handling change rejections and comments;
Retrieving and displaying approval histories;
Searching for various types of data for comparisons;
Listings for project change notice status and reports; and
Charting and graphics.
Many benefits have been derived from the ECC system. The system reduces cycle time in the engineering document review and approval by parallel electronic distribution. It also provides management visibility on tracking the progress of drawings in the review cycle, as well as the capability to convert all types of engineering documents into an electronic format for electronic distribution for review and approval. It can provide the capability to extract reports for metrics data. Documents are stored and exported in Computer Aided Acquisition and Logistics (CALS) support compliant format.
