Build your evidence pack before you write.

A proposal often becomes difficult before the writing begins. The project summary is in one folder, the approved resume is in another, and nobody is sure which version of a certification can be used. The draft then inherits that uncertainty.

An evidence pack gives the team a smaller, more dependable starting point: the source material it can use, what that material supports, and who is responsible for checking it. You can build one in a shared folder or spreadsheet before introducing any new software.

Start with the buyer’s questions.

Read the solicitation, amendments, instructions, and evaluation criteria together. Create one row for each requirement that needs a factual answer. Record the source location, the response section, the evidence needed, and an owner.

For federal negotiated acquisitions covered by FAR Part 15, evaluation follows the factors and subfactors in the solicitation. That makes the buyer’s stated criteria a useful organizing spine for the evidence pack. It does not mean every procurement uses the same sections or scoring approach.

Collect proof that supports the exact claim.

A company brochure may support a broad capability statement. It may not support a specific staffing commitment, performance metric, or certification claim. Keep the level of the evidence matched to the level of the statement.

  • Past performance: project scope, dates, your actual role, and the outcome you can substantiate.
  • People: the approved resume, relevant experience, and confirmation of any proposed availability.
  • Certifications: the current document, covered entity, scope, and expiration date.
  • Delivery: the operating method, responsibilities, dependencies, and constraints the team has approved.

Keep a claim register.

For each important claim, write down the supporting source, its version, the reviewer, and the review date. Add one of three working labels: supported, needs confirmation, or remove. These are internal review labels, not certifications or legal determinations.

Consider an illustrative claim: “We can assign a named project manager within ten business days.” A resume proves experience; it does not prove availability. The team also needs a staffing confirmation and an owner willing to approve that commitment.

Make unresolved items visible.

Missing evidence belongs in a short issue list with an owner and a due date. Avoid burying it inside prose or replacing it with a confident phrase. If the deadline arrives without confirmation, revise the statement to match what you can support or remove it.

Build a pack that can survive the next bid.

Separate reusable company material from opportunity-specific assumptions. Preserve the approved version, label sensitive material, and limit access to the people who need it. A new proposal should still check whether an older source is current and relevant.

The goal is not a larger document library. It is a response in which a reviewer can move from a requirement to a claim to its source without guessing. That is the discipline behind IntentBid’s approach to proposal work.

Source and scope.

FAR 15.305: Proposal evaluation describes the evaluation of competitive proposals under Part 15. The checklist above is IntentBid’s practical editorial guidance; the specific solicitation and applicable procurement rules remain the controlling references.

Build from evidence. Review with intent.
