My company bid for various sections a multi-disciplinary framework contract with MoD a few years ago - we'd been providing most lots we bid for for years. We didn't expect to get everything we targeted but were staggered not to be one of the successful suppliers for a particular aspect - so were the people who supervised the contracts for that aspect and who had no part in the bid selection process. I can't recall the specifics but there had been some serious errors in marking the bids so the entire process was re-run. Second time lucky for us on the aspect we had expected. I know it cost us umpteen man hours lost to re-bid even though most of the donkey work had been done already; what did it cost the tax payer? Not a lot in the grand scheme of things but how often does this stuff happen?
