A growing collection of rough tools, small trials and temporary fixes can begin to rely on you. Each once solved a real problem, but nobody decided whether to improve it, support it regularly or stop using it. The unfinished decisions start to take time from new work.
A working demonstration can also feel like a strong reason to continue. Return to the question it was meant to answer. Check what the result shows about usefulness, demand or practicality, and which important questions remain open.
Notice the unfinished decisions
Review older versions that people still use. Ask who supports each one, what it has taught the team and what needs deciding before more work is added.
Keep the test focused
If a version keeps gaining features, return to the original question. Choose the changes that will help answer it and put unrelated possibilities in a separate list.
Finish the learning
At the end of a trial, record the result and agree whether to continue, improve, delegate or stop. A clear ending lets colleagues use what you discovered.
