Uphill is thinking.
Downhill is doing.

Every task is a dot, and the hill tells you what kind of work is left

Drag each task to where it honestly sits. On the way up, you are still discovering what the work involves. Once it crests, the unknowns are settled and only the doing is left. Where a dot sits says more than any number could.

How to read one, in thirty seconds

Two tasks at "50%" can be nothing alike

One is halfway up the hill with the hardest questions still open. The other is halfway down with a clear run to the finish. On a status report they look identical. On a hill chart, nobody has to ask.

Update it together, once, with a note

Drag the dots while you talk through the board, then record the whole thing as a single check-in. Nothing saves until you do, so the history stays a record of real conversations rather than a log of every stray drag. When the project is done, play the history back and watch how the work actually moved.
