Why start / stop / continue retros on a whiteboard + BoardSnap is better than digital
Start / stop / continue produces the most immediately actionable retro output of any format. The three columns are already in action-item language — 'start doing X' is a task, not an observation. That directness makes the capture especially important: the stickies shouldn't disappear when the board is erased.
BoardSnap reads the three columns and outputs every commitment as a tri-state action item — open, in-progress, or done — ready to be checked at the next retro. The start commitments from last sprint become the 'did we actually do it?' check at the start of this one.
