Every project we run does a Friday demo. Thirty minutes. Working software in front of the client and the team. No slides, no “we are 80% done” — just the actual product running.
This ritual changes how engineers plan. You do not pick up a five-day task on a Tuesday, because there is nothing to demo by Friday. You break it into things that produce visible output by end of week. You front-load risk because you do not want to be in a meeting Friday morning saying “the API is done but the screen is not.”
It changes how clients engage too. They see progress. They do not worry. They give better feedback because they see the thing, not a description of the thing.
And it changes how teams catch mistakes. We have killed entire features at Friday demos because the moment we saw them working, it was obvious they were wrong. Better to learn that in week three than at launch.
Cost: about an hour of prep per person per week. Best hour we spend.
