CAP Answer

The answer is A: Incorrect and incomplete specifications.

The UK Health and Safety Executive (HSE) found that 44% of accidents involving control and safety systems were due to incorrect & incomplete specifications. Specifications are made up of two parts; the functional specification (what the system is supposed to do), and the integrity specification (how well it is supposed to do it).
