A pipeline is only useful if a stage tells you what happens next. If two stages have the same next action, you have one stage and some decoration.
Using the board
Sort by oldest, not by value
The point of a board is finding what has stopped moving. Highest-value first shows you what you already think about.
PipelineMove a card only when something actually changed
Advancing a stage because it has been a while makes the board lie to you, and the forecast with it.
Close lost with a reason
Price, timing, went with someone else, went quiet. Three months of reasons tells you which part of your funnel is leaking; three months of "lost" tells you nothing.
