A service becomes easier to buy when its edges are clear

Professional firms often describe flexibility as a virtue. It can be one. But a service that can become anything is difficult to evaluate, price and deliver. The buyer cannot see where the engagement ends, and the adviser cannot estimate the effort with confidence.

Define a useful unit of work. It should have an entry condition, a bounded process, a tangible output and a decision it enables. A diagnostic engagement might establish the causes of poor proposal conversion and recommend a next step. It need not promise to repair the entire commercial function.

Boundaries should describe reality rather than protect the supplier from every inconvenience. State what information is needed, how many stakeholders will participate and what happens if the initial assumption proves wrong. A well-designed service includes a sensible way to handle discovery without silently expanding forever.

Standardisation is most valuable in the repeatable parts: preparation, quality checks, documentation and handover. Keep room for judgment where the client's situation genuinely differs. A rigid template that forces every problem into the same answer is merely efficient at being wrong.

The commercial benefit is shared. Buyers can compare the offer and approve it with less uncertainty. Advisers can plan capacity and explain why additional work requires a new agreement.

Start with a service you have delivered enough times to understand. Productising an untested promise can make the packaging look mature before the method is ready.
