The broadest entry in the catalogue by design: an operation being planned, a procedure being written, a finding being disputed. The subject is open; the boundary is not. Every engagement fixes its question, its deliverable and its exclusions in writing before it opens — because consultancy without a declared boundary is where scope creep lives, and it is the client who pays for it.
Declared so the conversation happens before the campaign, not in the middle of it.
These drive effort, not price. Pricing is quoted after the specification call, together with the documents we will need from you.
