You can't separate 'requirements drift' and budgets. The requirement is stated by the customer, and it is for he to make adequate materiel and financial provision for any changes he makes. Not the procurer. If the procurer is having to do it, something has gone very badly wrong at requirements/committee stage, and it's far too late. Procurers are not represented on these committees. They're handed the committee's decision. If it's wrong in any way, some junior pleb has to either overrule the committee, or send it back. Both are fraught with danger, and frequent occurrences. If you bought the approved requirement every time, things would be an even bigger ****show!
