A few things lend themselves directly from the article: More expertise on the buyer side overall (less reliance on a vendor to co-author the RFP). Better processes on the buyer side in order to lessen the one-upmanship regarding requirements.
Both of these are easier said than done, of course, because if you had the expertise and the processes, why even hire somebody else? In ideal world, the answer is that you could do it, but you chose to spend your resources (your experts' time) somewhere else, e.g. writing more RFPs.
Probably not very realistic for most businesses, but on the scale of governments, they really ought to have the necessary in house expertise. (But I'm sure they almost never do, whether it's building a bridge, buying a tank or developing an IT project.)
