QUIZ #7: Basic Software Validation Principles
Answer each of the following questions with TRUE or FALSE. Good luck!
- It is not necessary to identify formal specifications before entering the the design phase of software development.
- Well-documented software specifications will facilitate validation of the system later.
- If software is a commercial program purchased off-the-shelf, the user is not responsible for performing structural validation.
- There is little additional benefit to recording actual results when testing software; it is sufficient to record a PASS or FAIL assessment as long as established PASS/FAIL criteria have been set.
- Formal hazard analysis is beneficial for software used as components in medical devices only.
- If a software system has been used successfully for many years, it has been proven by experience and documented by use. It is therefore exempt from any requirements for formal validation.
- Diagnostic tests supplied by the vendor can be helpful in conducting installation qualifications.
- Systems that control or generate regulated data must be validated for their ability to discern invalid or altered records.
- Manual audit trails are sufficient to track changes to regulated electronic records, provided that both the date and time of documented changes are recorded.
