Engineering Change Management (Part 7 of 8)
“Slowness to change usually means fear of the new.” – Philip Crosby“
Change is part and parcel of our life. Some changes are planned like a change of business, job, shifting to another city or country, the birth of a baby etc. But there are many which are not planned and are thrown on us like COVID-19, demonetization etc. In both the situation, we have to adapt ourselves to the new reality, at times with some difficulty.
The key objective of the change management process is to understand the need and expectation of the customer & relevant interested parties and make the changes in such a way that customer requirement is taken care and satisfaction of all the relevant interested parties including the organization is ensured.
As per ISO 9000: 2015, clause 3.0, following are some of the key definitions related to the design process
Configuration Management (Clause 3.3.9): It is coordinated activities to direct and control configuration.
Note: establish and maintain control of a product or service and its product configuration information throughout the life cycle of the product.
Change Control (Clause 3.3.10): Activities for control of the output after formal approval of its product configuration information.

- Product drawing
- Component drawing
All relevant PPAP documents including following
- Process Flow Chart
- Control Plan

- Communication to Supplier if purchased
- Changes in Supplier Control plan & Work instruction
- In-process Inspection sheet
- Pre-despatch Inspection sheet
- SPC chart & comments (if Special Characteristic)
- MSA Study (if it has resulted in a change in measuring instrument)
- May be few more….
Benefits to Organization:
- Systematic and effective change management

- Enhanced satisfaction for the customer and all relevant interested parties
- How often Cross-Functional Team (CFT) approach is used for change management process?
- How often customer approval/waiver is taken where needed?
