15-Minute Retrospectives for Busy Developers

"We don't have time for a retro this sprint. Let's just skip it."

Every Scrum Master has heard this. When the deadline is looming and the backlog is overflowing, a 90-minute therapy session feels counterproductive. But skipping the retro is the first step toward process decay.

The Solution: The 15-Minute Micro-Retro.


Format 1: The "One Thing" Retro

This is the absolute fastest way to generate an action item. You abandon all boards, categories, and deep analysis.

  • Minute 0-3 (Brainstorming): Everyone writes down exactly ONE thing that slowed them down this sprint.
  • Minute 3-5 (Voting): Group the cards instantly using AI and let everyone vote on the single biggest bottleneck.
  • Minute 5-15 (Solutioning): The entire remaining 10 minutes is spent designing a fix for that one specific bottleneck.

Why it works: It acknowledges that you can't fix everything. By focusing 100% of your limited time on exactly one issue, you guarantee a high-quality action item.

Format 2: The "Keep / Drop" Lean Format

The classic Start, Stop, Continue format has three columns. The Keep / Drop format cuts that down to two, forcing binary decisions.

  • Keep: What process, tool, or meeting is working perfectly and must be preserved?
  • Drop: What is actively wasting our time and should be eliminated immediately?

Why it works: It shifts the focus away from adding new, complex processes (which take time to debate) and focuses on immediate elimination. It is much faster to agree to "drop the daily 4 PM sync" than to invent a new workflow.

Format 3: Rate the Sprint (1-10)

This is a qualitative, pulse-check retro designed for high-performing teams that just need a quick alignment check.

  • Minute 0-2: Every team member drops a card with a number from 1 to 10 rating the sprint, plus one sentence justifying the score.
  • Minute 2-10: The Scrum Master identifies the lowest scores and asks those individuals, "What would it take to make your sprint a 10 next time?"
  • Minute 10-15: Formulate an action item based on their answer.

The Secret Weapon: Tooling

If you are trying to run a 15-minute retro over a Zoom call using a generic shared document, you will fail. The administrative overhead (sharing links, defining columns, manually counting votes) will eat 8 of your 15 minutes.

To pull this off, you need a dedicated, real-time board.
