A demonstration needs a decision criterion

A demonstration can impress a room while leaving the purchase unresolved. The audience sees many capabilities but has no agreed way to judge whether those capabilities solve the problem that matters.

Before demonstrating, ask what the buyer needs to learn. Choose a realistic task, define the expected outcome and identify the conditions under which the demonstration would be unconvincing. This gives the session a purpose beyond showing breadth.

Use representative inputs where possible. A carefully prepared example may be appropriate for explanation, but disclose the preparation. Do not allow a rehearsed path to imply that unstructured real-world work will behave identically.

Show an exception as well as a smooth case. Buyers need to understand what happens when information is missing, the process changes or the output is wrong. A credible failure path can be more useful than another successful click-through.

Keep the discussion attached to the decision criterion. If a feature is interesting but irrelevant, note it for later. The buyer should leave knowing what was established, what remains uncertain and what further evaluation would be necessary.

For a service business, a demonstration might be a sample diagnostic, a worked decision or a review of an anonymised artefact. The same rule applies: demonstrate the quality of the work without implying that a small sample guarantees the outcome of a full engagement.
