It seems that the tides have turned in the Government contracting world firmly in the direction of IDIQs and GSA/VA schedules. If you are the Government, it is hard to imagine why it would not be the case. Instead of a lengthy 12-18 months procurement process, the Government can award a contract in two to four months, reducing risk of protest. In addition, the budget approval and end of the fiscal year window shrinking, it is hard to imagine that anything will change any time soon.
We all have been on a proposal effort where suddenly everything seems to be falling apart, and panic sets in.
