Discovery: Three Steps
Every discovery conversation follows the same sequence:
- Listen — capture what the stakeholder actually said, verbatim. Don't interpret yet
- Translate — convert their preference words into testable, bounded constraints
- Write it down — produce a translation table row for every item
The translation test: when a stakeholder says "seamless," ask: what would break the experience? That answer is the actual testable constraint. "Seamless" becomes "p95 latency under 800ms" or "no re-authentication required between steps."
Why verbatim capture matters: paraphrasing in the moment changes the stakeholder's words into your interpretation. When you review assumptions with the stakeholder later, they need to recognise what they said — not your summary of it.
The Four Discovery Question Categories
Cover all four before moving to design. Missing any one leaves a gap that surfaces as a production failure or a stakeholder objection after launch.
| Category | What it surfaces | Example question to ask |
|---|---|---|
| Must do | The core capability requirement | "What must the system be able to do on day one?" |
| Must NOT do | Hard prohibitions (regulatory, brand, operational) | "What would make this immediately unacceptable, regardless of how well everything else works?" |
| Must cost (performance SLA) | Latency, throughput, uptime requirements | "What response time would make users abandon the workflow?" |
| Must prove (compliance/audit) | Regulatory, explainability, and audit requirements | "Who will audit this system, what will they ask for, and how soon?" |
The exam trap: a question describing a design process where the architect moved to architecture before collecting "must prove" requirements. A regulatory control that doesn't exist in the design doc can't be retrofitted cheaply. The cost of discovering compliance requirements post-design is architectural — not just documentation.
The Translation Table
One row per discovery item, four columns:
| Stakeholder said | Implied constraint | Architectural decision | Assumption (labeled, with owner) |
|---|---|---|---|
| "Seamless and instant" | p95 < 800 ms | Streaming required; no blocking multi-step routing before first response | Assumes WiFi connectivity; confirm with infra lead |
| "We can't store any customer data" | Zero PII persistence | Stateless session design; no conversation logging | Legal must confirm "any data" applies to audit logs too |
| "The lawyers need to see every decision" | Full audit trail, immutable, queryable | Every model call and tool invocation logged with inputs and outputs | Confirm retention period with legal |
The documentation completeness test: can a competent Architect who was not in the room make a safe change after reading this document? If not — because decisions are missing, alternatives aren't recorded, or assumptions are unlabeled — the document is incomplete. Required elements: decision, rejected alternatives, tradeoff, owner, and evidence (with assumptions explicitly labeled as such, with the person who will confirm them).
Tradeoff Framing — Three Elements
Every tradeoff presented to a stakeholder must contain all three elements:
- Gain — what this option provides
- Give-up — what this option costs or forfeits
- Reversal cost — what it costs to undo this decision after the system is built around it
Why Reversal Cost Changes the Meeting
Gain and give-up are almost always in every presentation. Reversal cost is the element most often omitted — and it's the one that most often changes the stakeholder's decision.
