Proposal Graphics and Action Captions: Connecting Evidence to Evaluation Criteria

Give a Proposal Graphic a Clear Job

A process diagram can be attractive without helping a reader understand the proposed work. Before adding one, identify the question it answers: who owns a handoff, how a risk is controlled, where a dependency sits, or which part of an approach addresses a stated requirement. A caption can help the reader locate that explanation. It cannot turn an unsupported drawing into proof of capability.

Use captions as part of the technical narrative, alongside the underlying evidence and the proposal instructions. The recommendations below are an editing method, not an evaluation rule or a promise about how an agency will score a figure.

Read Instructions and Evaluation Factors Separately

Locate the actual instructions and evaluation factors in the solicitation and its amendments. In the Uniform Contract Format, Section L contains instructions, conditions and notices to offerors, while Section M identifies evaluation factors and their relative importance. Other formats may organize these matters differently. Do not assume that every solicitation uses those labels or that a requirement can be inferred from a generic template.

For competitive proposals evaluated under FAR 15.305, the agency assesses proposals using the factors and subfactors stated in the solicitation. A compelling caption does not create an additional factor, require an evaluator to award points, or replace a required narrative or attachment.

Build a Caption Around Three Elements

First identify what the figure shows. Next explain the specific relationship, action or limitation that matters. Finally point to the applicable solicitation reference and supporting proposal material. For a handoff diagram, a useful caption could identify the two responsible roles, explain when a record moves between them, and direct the reader to the staffing and escalation sections.

Use the agency's terminology where it accurately describes the approach. Cite exact section identifiers only after checking them against the current solicitation. Avoid treating a caption as a place to add promises that the delivery team has not reviewed.

Keep Numerical and Performance Claims Supportable

Consider a hypothetical network-availability requirement. A diagram may show two network paths, but that drawing alone does not establish an availability percentage. The caption should explain the architecture and cite the evidence or analysis, assumptions and dependencies behind any performance claim. If the percentage has not been substantiated, do not add it because it sounds persuasive.

A review should distinguish a proposed design, an estimate, a tested result and a contractual commitment. State which is being shown. A caption should not describe an estimate as achieved performance, omit a significant dependency or imply that redundant components eliminate all failure modes.

Make the Graphic and Narrative Agree

Check names, dates, role assignments and quantities against the surrounding proposal. If the staffing table assigns one owner and the diagram assigns another, resolve the discrepancy rather than explaining it away in the caption. Ensure that a callout points to the intended object and that the figure reference in the text is correct.

Provide a readable explanation of the information needed to understand the approach; do not rely on color or tiny text as its only carrier. Follow the solicitation's accessibility, format and page-limit instructions. These usability suggestions do not establish that a particular diagram satisfies a legal accessibility standard.

Review Captions With the Evidence Owner

Ask a reviewer who did not draw the figure to explain its message. Can they identify the proposed action and the source of support? Does the caption make a claim that the figure cannot demonstrate? Are limitations or assumptions missing? Route technical claims to the person responsible for the approach and commercial commitments to the appropriate proposal authority.

When a caption is unclear, the correction may belong in the drawing, the narrative, the evidence reference or all three. Avoid assuming that stronger wording alone resolves an underlying gap.

A Practical Editing Checklist

• Identify the question the figure answers and its role in the response.
• Check the current instruction and evaluation references.
• Separate proposed, estimated and demonstrated results.
• Trace every material numerical claim to reviewed support.
• Check role names and dependencies against the rest of the proposal.
• Remove decorative or redundant detail that obscures the explanation.
• Recheck figure numbering and references after final pagination.

Use Captions to Explain, Not to Guarantee

The useful outcome of this editing process is a clearer, more consistent explanation of the offer. It does not guarantee acceptability, a rating, an award or delivery performance. Follow the actual solicitation and resolve uncertain requirements through the channels and deadlines it provides.
