What you will learn

  • Terms are grouped alphabetically; use the chapter list to jump to a letter.
  • Where a term has a regulatory home, the FAR or CFR reference is given so you can read the source.
  • Proposal-process terms (color teams, win themes, ghosting) are industry practice, not regulation; definitions reflect common usage.
  • State and local procurement uses different words for similar ideas; the state guide covers those.

Before you go

Questions people ask

What is the difference between an RFP, an RFQ and an IFB?
An RFP is the solicitation for a negotiated procurement evaluated on factors; an RFQ asks for quotations, usually under simplified procedures, and a quotation is not an offer; an IFB is a sealed bid awarded on price to the lowest responsive, responsible bidder.
What does "technically acceptable" mean?
That a proposal meets the minimum requirements for each non-price factor. Under LPTA, award goes to the lowest-priced technically acceptable proposal; strengths beyond acceptability earn nothing.
What is the difference between a weakness and a deficiency?
A weakness increases the risk of unsuccessful performance; a deficiency is a failure to meet a requirement or a combination of significant weaknesses that makes the risk unacceptable. A deficiency can make a proposal unawardable.
What is a Section J attachment?
Part III of the Uniform Contract Format lists the documents, exhibits and attachments that form part of the solicitation, such as the PWS, wage determinations and pricing templates. Requirements in Section J are as binding as those in the body.
Where can I read the FAR?
The official text is at acquisition.gov, maintained by the FAR Council. Agency supplements such as the DFARS are published alongside it.
How ProposalWorkspace handles this

A workspace that speaks the vocabulary

ProposalWorkspace reads solicitations in this vocabulary: it extracts Section L, M and C requirements with citations, builds outlines that follow the UCF, tracks Pink, Red and Gold Team milestones, and its AI teammate answers questions about a specific RFP with page references, so the terms on this page are the terms you work in.

Capture planning before the RFP drops: customer calls, industry days and draft RFP comments

By the time an RFP is published, the shape of the requirement, the evaluation factors and often the winner have been influenced by the companies that showed up early. Capture is that early work. This guide explains what it is, what is allowed, and how a small team can do it well.
