Identifying and Recording Design Changes In ISO 9001 Standards

Identifying and Recording Design Changes In ISO 9001 Standards

The documentation for design changes in ISO 9001 Standards should comprise the change proposal, the results of the evaluation, the instructions for change and traceability in the changed documents to the source and nature of the change. You will therefore need:
- A Change Request form which contains the reason for change and the
results of the evaluation – this is used to initiate the change and obtain
approval before being implemented.
- A Change Notice that provides instructions defining what has to be changed this is issued following approval of the change as instructions to the owners of the various documents that are affected by the change.
- A Change Record that describes what has been changed – this usually forms part of the document that has been changed and can be either in the form of a box at the side of the sheet (as with drawings) or in the form of a table on a separate sheet (as with specifications).
Where the evaluation of the change requires further design work and possibly experimentation and testing, the results for such activities should be documented to form part of the change documentation.
At each design review a design baseline should be established which identifies the design documentation that has been approved. The baseline
should be recorded and change control procedures employed to deal with any changes. These change procedures should provide a means for formally
requesting or proposing changes to the design. For complex designs you may prefer to separate proposals from instructions and have one form for proposing design changes and another form for promulgating design changes after approval. You will need a central registry to collect all proposed changes and provide a means for screening those that are not suitable to go before the review board, (either because they duplicate proposals already made or because they may not satisfy certain acceptance criteria which you have prescribed). On receipt, the change proposals should be identified with a unique number that can be used on all related documentation that is subsequently produced. The change proposal needs to:
- Identify the product of which the design is to be changed
- State the nature of the proposed change identify the principal requirements, specifications, drawings or other design documents which are affected by the change
- State the reasons for the change either directly or by reference to failure
reports, nonconformity reports, customer requests or other sources
- Provide for the results of the evaluation, review and decision to be
recorded
