Initial scoping conversation
Produced: a short note on the problem, constraints, known stakeholders and open questions. Signed off by the client sponsor as an accurate basis for drafting scope. If the problem is not ready to scope, the work stops there.
Written scope document
Produced: objectives, exclusions, deliverables, decision owners, working language and handover expectations. Signed off by the sponsor and the trailhatchix engagement lead. If scope needs to change mid-engagement, a variation note states the change before the work continues.
Decision log
Produced: a decision, dated, with options considered, owner, rationale and consequences. Signed off by the person with authority to make that decision. The log prevents old questions being reopened without acknowledging the cost of doing so.
Delivery cadence
Produced: agreed checkpoints, work-in-progress review and escalation route. Signed off through attendance and written acceptance of checkpoint notes. If a new dependency appears, it is logged as a risk, blocker or variation.
Handover documentation
Produced: final documents, open decisions, assumptions, owners and next-step recommendations. Signed off by the sponsor or named receiving owner. Work is handed over, not handed off; the receiving owner must know what they are accepting.
Post-engagement review
Produced: a close-out note covering what was delivered, what changed, what remains unresolved and what should not be continued. Signed off by both sides as a record, not as a claim of guaranteed outcome.
