Easy. It’s called Business.
1. If Company A wins Gap-SAR and loses Long-SAR, it’s got a few years of revenue then it looks elsewhere with a new line in its CV. If it loses interest, see 2.
2. If it wins one or both and doesn’t perform, the customer implements the incentive system, so Company A loses revenue and reputation until it becomes more profitable to perform, when revenue recovers and, a few years behind, the lost reputation fades. All the while, lives are saved, perhaps not always to the standard of the perfectionist but whisper it - a perfect world doesn’t actually exist - and the taxpayer gets reasonable value for money.
Don’t look for the psychology – follow the money.
