Name the question behind the demonstration.
A prototype should have a reason for existing. A screen sequence might help people discuss the order of a task. A simple technical sample might examine whether a particular file can be read. Combining both into one presentation does not automatically test an entire product.
For example, a demonstration can display a sample report after a button is selected. If that report was prepared in advance, the demonstration shows a possible presentation rather than a working report-generation service. The distinction belongs in the explanation, not in an obscure note.
Label the real and simulated parts.
Identify which interactions are functional, which information is invented, and which dependencies are absent. A short boundary statement can make a review more useful: navigation is interactive, sample records are fictional, and no connection to an operational system is present.
Use sample information that is suitable for the question. Real customer records are not automatically necessary for a conversation about layout or sequence. Keeping the demonstration limited can also make it easier for participants to concentrate on the intended issue.
Plan what would be needed next.
Before treating a prototype as a starting point for implementation, consider the parts it did not address. Access management, error handling, data retention, operational ownership, and ongoing maintenance may need separate work. The relevant responsibilities depend on the application.
Record what can be retained, what would need replacement, and what has not been evaluated. This keeps a promising idea from acquiring commitments through appearance alone. A prototype can support a decision without being described as ready for release.
