I'm working as a programmer in a load cell manufacturing company.
We develop our own software for load cell manufacturing and testing purposes.
Quality Assurance Department of our company has requested to perform periodical verification and validation tests (once a year) for our released software which has been already tested. (They are considering software as a equipment such as a multi-meters which requires periodical verification.)
My opinion is there is no point of testing a released software from time to time.
So I'm here to find answers for the following questions from some experts:
- Is it a common practice to perform validation or verification tests time to time for industrial software which is already tested and released?
- Whether it is a common practice or not, are there any supporting reasons to do so?
