From requirements to a working start
Set the decision boundary
Name the commercial problem, the buyer segment, the sales-cycle constraint, the people who must participate, and the decision that the engagement must help you make. A brief is not a service wish list.
Build a comparable shortlist
Research a small set against the same requirements. Ask each candidate to show relevant context and name the team that would deliver; do not use a logo wall as the comparison.
Run the evaluation
Use the same operating-fit questions, evidence requests, and proposal scorecard for each candidate. Record uncertainty rather than treating a polished answer as proof.
Make the commercial terms workable
Clarify scope boundaries, ownership of work and data, staffing changes, reporting, renewal, termination, and a practical handoff before signing.
Start with a 90-day learning plan
Agree the diagnosis, early outputs, access to subject-matter experts and sales feedback, decision cadence, and what would cause the team to adapt or stop.
