I was told my a upper management Contracting Officer that I must fill out and have the 2689 approved prior to synopsis. I have always used a Sources Sought and/or RFI to gauge interest, then synopsis per the requirements of the FAR. I have never considered that there was an order in which these needed to be completed. I can not find a reference to this in the FAR or GSAM. Is there a FAR regulation that covers this or is it just good contracting practice. I'm good either way, but am concerned I have been doing it incorrectly for some time.
