Just the standard procurement. It's all about risk calculation. Award the contract to a branded company, because they tell you that no one got fired for buying IBM. From PwC side, "we already got the work, now just do the minimal thing to finish off the ceremony. Keep it crap and keep the work coming". Work comes back to you not because you have been delivering great products, but because they got locked into brand names and the mess that was created.
