Appendix E — BRD Field Guide Resources

The operational companion to Chapter 2 • Updated 2026-06-11

Appendix E of The Defensible Decision is the operational companion to Chapter 2. Chapter 2 covers the six-field cognitive minimum: the discipline of asking the right questions before any chart is built. Appendix E covers what the discipline turns into when the work has to ship: the eight-section template that gets signed off, the technique that produces a first-draft BRD from a meeting that already happened, and worked walkthroughs against five reference datasets.

This page hosts the assets the appendix references: the template in copy-paste markdown form, the AIRS completed exemplar, four starter BRDs intentionally underspecified for practice, and the three prompts that drive the transcript-driven elicitation loop.

Every artifact is available as both Markdown and Word (.docx). Markdown for copy-paste into Copilot or authoring in a text editor; Word for the review workflow analysts actually use to sign off on a BRD — edit in Word, route through stakeholders, get signatures.

The eight-section template

Reference BRDs — five exemplars, four starters

The companion site ships nine reference BRDs across five completed exemplar domains and four starter datasets. The exemplars are the finished state to compare your work against; the starters are the exercise surface, each paired with a same-domain completed exemplar for direct comparison after you complete Sections 4–8.

Pick a starter whose domain is closest to your working context, complete it using the techniques in Appendix E and the prompts below, and compare your version against the same-domain completed exemplar (direct comparison) or the AIRS exemplar (cross-domain shape check). The point is not to match either exemplar field for field; it is to feel which sections are easy, which sections force a stakeholder conversation, and which sections you are tempted to skip because they are uncomfortable. The discomfort is the data.

The transcript-driven elicitation prompts

The three prompts the appendix references — one for the common case, two for the situations that need a separate first pass.

Forthcoming sections (future editions)

Sections 1 and 2 are complete in this edition. The following sections are planned for future editions of Appendix E.
