Make a rough prototype
WhenWhen you cannot choose a workable approach.
Make a quick sketch, sample or mock-up of an uncertain part. Try the simplest version of how it would be used, then note what the prototype makes clear.
Why it works
A small crossing can tell you about the river.
Start tiny
Sketch the uncertain part and how it would be used.
What you’ll notice
You have a concrete version to examine before committing more work.
When it slips
If the test needs too much time or money, reduce what it tries to answer.
