1. Starting without the standard in mind
Probably the biggest problem causing issue in a FIPS 140-2 validation project is when the developer decides to 'back into' the standard after the fact. Trying to validate a product that was developed without being mapped to the standard is more difficult at the very least and has a potential for failure at the worst.
FIPS 140-2 has many specific system requirements including: self-test on start-up, where the integrity of the module has to be verified and all cryptographic functions have to be run against known answer tests to ensure correct operation.
