Goal, users, constraints, existing evidence, and the decision that cannot remain vague.
Architecture Decision Sprint / ADS 01
A fixed-scope decision sprint for a future product, platform, or major workflow facing an expensive build, integration, rewrite, or architecture choice before production complexity becomes permanent.
01 / When it fits
02 / What you receive
Actors, state, boundaries, critical paths, integrations, and ownership in one legible model.
Options, constraints, tradeoffs, rejected paths, and the reasoning the team can revisit later.
The assumptions that should be tested before the team commits to the expensive parts.
A practical first 30 days with boundaries, milestones, and decisions that should wait.
03 / Five days
Goal, users, constraints, existing evidence, and the decision that cannot remain vague.
Workflow, state, boundaries, dependencies, failure surfaces, and viable options.
Tradeoffs, validation needs, target architecture, and implementation sequence.
Readout, challenge session, final decision package, and clear next actions.
04 / What it unlocks
System boundaries, contracts, risks, rejected paths, validation needs, and an executable first sequence.
Run one real workflow through data, integrations, deployment, tests, observability, and failure handling.
Add product surfaces and integrations through explicit seams, repeatable releases, and ownership the team can carry.
The sprint delivers the week-one decision package and implementation sequence. Later horizons describe the intended trajectory, not bundled implementation or a guaranteed schedule.
05 / See the output
This illustrative example uses a fictional field-service product. It shows how the sprint narrows scope, compares options, and turns tradeoffs into an implementation sequence.
06 / Practical questions
Usually a forty-five minute scope call plus the product brief, existing diagrams or decision notes, and focused access to the people or evidence closest to the decision. Access boundaries and NDA requirements are agreed before work begins.
That is common. Existing documents are useful evidence, not an entry requirement. I reconstruct the critical workflow from conversations, code or prototypes, interfaces, constraints, and observed behavior.
Plan for the initial scope call, short targeted conversations during the week, and a Day 5 challenge and readout session. I do the analysis and synthesis directly.
I reframe it before the sprint starts. If a five-day architecture decision is not the useful next step, I will say no-fit and explain the smaller validation or operational work that should happen first.
The sprint is a decision engagement, not bundled implementation. If hands-on follow-through is useful, we define it separately after the team has reviewed and accepted the decision package.
07 / Conversation
Share the product context and the decision that keeps moving. I will reply with fit or no-fit, the next useful step, and a fixed fee if the sprint fits. NDA and access boundaries are agreed before work begins.
