I just lost a city contract for landscaping services (NAICS 561730) because I missed a form. The city procurement portal said the bid was non-responsive because of the missing form. I asked for a debrief, and the contracting officer mentioned something about a "compliance matrix" that could have helped. I've heard the term before but never really understood it.
What is a compliance matrix? How do you build one from the solicitation, especially from Section L and Section M? Do you include the matrix in your actual proposal, or is it just an internal tool?
