Agree what is in, what is out, and what "done" means.
Every engagement starts with a written scope. It names the assets, systems or decisions in scope, the exclusions, the testing or review windows, the rules of engagement, the escalation contacts on both sides, and the specific questions the work has to answer.
The scope also names the consultants. You know who is doing the work before it starts, and the price is fixed against the scope rather than against the hours it takes us.
- A scope document with assets, exclusions, windows and rules of engagement
- Named consultants and a named point of contact
- A fixed price and a delivery date
