The procurement lifecycle, start to finish

The stages, in order

Every federal purchase, from a small purchase-card buy to a nine-figure program, moves through some version of the same lifecycle. Knowing the stages matters because each one narrows what happens next. Most businesses start watching for opportunities the day a solicitation posts, which is already the fourth or fifth stage. By then, most of the influence is already gone.

Stage	What is happening	Can you still shape it
Need identified	An agency program office decides it needs something	No, this happens internally
Market research	The agency asks industry what is out there, often through a sources sought notice or an RFI	Yes, this is the best window you get
Requirement written	The agency turns what it learned into a statement of work and evaluation factors	Indirectly, through what you said during market research
Solicitation posted	The formal request goes public, with a deadline	No shaping left, only responding
Questions	Offerors ask the contracting officer to clarify the requirement	Yes, a good question can fix an ambiguous requirement for everyone
Proposals submitted	Offerors submit by the deadline, no exceptions	This is your one real shot
Evaluation	The agency scores proposals against the stated factors	No, you are out of the room
Award	A winner is announced, with debriefings available to the rest	No
Performance	The winner does the work, under a contracting officer's representative	Only if you won, or are subcontracting to whoever did
Closeout or recompete	The contract ends, and the need either goes away or comes back up for bid	Watching for the recompete is its own skill

Why market research is the stage that matters most

By the time a solicitation posts, the requirement is usually already shaped: the statement of work is written, the evaluation factors are set, and the agency often already has a good idea of who can do the work. A sources sought notice or RFI is the government asking, in public, what industry can actually deliver. Answering one puts your capabilities in front of the person writing the requirement before it locks in. It is also, structurally, the lowest-competition stage, because most businesses only pay attention once there is a chance to get paid.

Entering late is not disqualifying, it is just harder

Showing up at the solicitation stage is not a mistake, it is just the default, and the default is a crowded room. You can still win from there. It only means your influence is limited to the questions period and the proposal itself, both of which matter, neither of which reshapes the requirement.

After award, a different kind of watching starts

Performance is its own long stage, often years, and closeout is not really an ending. Many requirements do not disappear, they recompete: the same need goes back out to bid, usually with the incumbent holding an advantage nobody else has. Recognizing that a contract you lost, or one you were never watching, is heading toward recompete is a separate skill from finding new work, covered in hunting recompetes.
