A substitution should never become an automatic yes just because the original product is unavailable.
Before approving one, an owner should be able to answer four questions:
• What changed from the specified item?
• Is the performance truly equivalent?
• Does the cost or schedule change?
• Who gave written approval?
A simple review now can prevent a surprise later.
