Retrospective formats, compared
The format is not the problem. Every retro format fails the same way — cards without owners — and succeeds the same way. Here are four formats, what each is good at, and where each dies.
Start · Stop · Continue
Three verbs, one behavior per card, nobody named. Its strength is bluntness: the STOP pile is the conversation the team was avoiding, and it forces the question "what do we protect?" (CONTINUE) that pure problem-solving retros skip. It dies when CONTINUE is uncapped — praise is safe, and an open CONTINUE column turns the wall into a compliment exchange. Cap it at three per person. Full printable kit: Start · Stop · Continue.
4Ls — liked, learned, lacked, longed for
Four gentler columns. Better for sensitive rooms and client-adjacent teams, because "lacked" and "longed for" let people criticize the situation instead of the plan. It dies in vagueness: "learned: communication" is a poster, not an action — the format needs a specificity rule (one line a stranger could act on) bolted on.
Keep / Change / Try
The lightweight: what stays, what bends, what we have never tried. Good for short cycles and first retros with a nervous team — three minutes to explain. It dies without an owner column: "change" items that nobody owns become next retro's déjà vu.
The timeline retro
Reconstruct the sprint or project on a line, then mark peaks and valleys along it. Best for long projects and incidents, where the story is the lesson and causality matters. It dies when the group has different memories of the same week — which is information, write it down, and switch formats for the action round.
The discipline every format needs
Whatever the columns say: one owner, one date, per committed card — said out loud, to the room, and the wall gets photographed before anyone moves. The next retro opens with that photo, not with forgetting. Formats are interchangeable; the owner-and-date rule is the whole difference between a retro and a meeting people forget.
Questions people ask
Which format for a first retro with a cautious team?
Keep / Change / Try, written in pairs — two names per card halves the exposure. Move to Start · Stop · Continue once the team has survived one cycle of honest STOP cards.
How often should the format rotate?
Once a quarter, or the moment the same cards come back two cycles running — repeated cards are not a format problem, they are an ownership problem. Fix the owner-and-date rule before touching the columns.
