Record Keeping

Record keeping is a critical part of all quality assurance programs. Standard forms similar to those

that appear in this manual should be developed for individual programs. Three things to consider in
the development of record forms are:

• Does the form serve a necessary function?

• Is the documentation complete?

• Will the forms be filed in such a manner that they can easily be retrieved when needed?

8.1.7. Summary of Quality Assurance Checks

The following items should be checked on a regularly scheduled basis to assure high quality data

from the M6200E. See Table 8-3 for a summary of activities. Also the QA Handbook should be
checked for specific procedures.
