I have my own take on the GAO Bid Protest annual report.  My view is that protests are increasing at both GAO and the COFC.  See my write-up and analysis HERE and attached..

Interesting.  Thank you for sharing.

One wonders whether the "Task Order" distinction has any real meaning anymore, considering for example that GSA OASIS "task orders" are functionally indistinguishable from open-market contract competitions. When you have a $100M procurement employing a 2-phase down-select, oral presentations, evaluation factors and sub-factors, a schedule of hundreds of prospective bidders, and a best value award basis, the protest landscape is practically identical whether it's a TO or a C-type contract. Obviously, the protest threshold is different, but that's almost a cheat (not that I'm complaining, but I don't think it's a stretch to say the primary reasoning behind the $10M threshold is to temper GAO workload.)
