The Grinch Retrospective

Choose this exercise

Purpose: Collect structured feedback on team drivers, risks, fresh ideas, and peer appreciation from a recent work period.

Use it when: Sprint reviews, end-of-quarter retrospectives, or seasonal project closeouts where a playful metaphor helps structure review.

Skip it when: Serious post-mortems after severe operational failure, or with teams unfamiliar with or resistant to seasonal cartoon themes.

Group arrangement: Individual silent writing, followed by whole-room clustering for 4 to 8 people or 4 column teams for 9 to 24 people, then full-group action planning

Timing: UWT suggested duration for a standard 45-minute sprint retrospective

Materials and tools

• Whiteboard or wall space divided into 4 columns
• Sticky notes (at least 15 notes per participant)
• Dark felt-tip pens (1 per participant)
• Digital whiteboard board (for remote or hybrid delivery)

Before participants arrive

1. Draw 4 columns on a shared wall or board: Roast Beast, The Grinch, Cindy Lou, and Max.
2. Write the guiding prompt under each column header.
3. Place sticky notes and pens within reach of all participants.

Say this to open

Welcome to our retrospective. Today we are using four categories inspired by the Grinch story to review our recent work. Roast Beast covers what fueled our work. The Grinch highlights what was toxic, risky, or to be avoided. Cindy Lou captures fresh ideas we should try. Max recognizes people who supported us no matter what. You will write your observations quietly before we cluster them and choose action steps.

How to run it

1. Introduce prompts and silent writing 8 minutes

   Read the column prompts aloud. Give an explicit neutral example for clarity, such as 'Roast Beast: daily standups kept blockers clear; The Grinch: manual deployment errors'. Direct everyone to write one idea per sticky note across any of the four columns. Participants may contribute as many or as few notes as they wish, or choose not to post on specific topics.

2. Post and group notes 12 minutes

   Invite participants to post their notes under the matching columns. For 4 to 8 people, cluster notes as one full room. For 9 to 24 people, divide into exactly 4 column teams of roughly equal size (2 to 6 people each), assigning one team per column. Each team clusters duplicates and names themes for its assigned column. Allow 2 minutes for everyone to read the full board.

3. Discuss themes and select focus 15 minutes

   Facilitate a room discussion on the major clusters. Spend roughly 4 minutes on successes and recognition (Roast Beast and Max), and 11 minutes analyzing problems to avoid and new proposals (The Grinch and Cindy Lou). Select 1 to 2 critical themes to address next cycle.

4. Draft concrete actions and close 10 minutes

   Ask the team to write clear action items for the selected themes. Each action item must state a concrete task, a single owner, and a deadline. Close the session by recording the final commitments in the team tracker.

Debrief questions

• Which blocker in The Grinch category poses the greatest risk if left unaddressed?
• What positive habit from Roast Beast or Max should we make standard practice?
• Which Cindy Lou idea can we test within the next two weeks?

Finished output: A board of categorized team feedback and a written list of 1 to 3 owned action commitments for the next work cycle.

Remote

Set up a digital board with four columns: Roast Beast, The Grinch, Cindy Lou, and Max. Run the silent writing phase with video on and microphones muted. Use digital grouping tools to cluster notes by theme. Use an open mic or chat queue for discussion and log the agreed action items on a dedicated board panel.

Hybrid

Provide a shared digital whiteboard accessible to both in-person and remote participants. In-person participants type on their own devices or post physical notes transcribed by a designated volunteer scribe or co-facilitator. A remote co-facilitator monitors chat and brings remote comments into room discussions before each column transition.

Access and participation choices

• Participants may submit anonymous notes via a digital link or plain sticky notes.
• Any participant may opt out of sharing personal recognition or private concerns without explanation.
• Clear printed column headers ensure readability for people who prefer text prompts over cultural references.

If the session gets stuck

Team members do not know the Grinch story and are confused by the column names.

Ignore the story lore and refer directly to the functional questions: what fueled us, what to avoid, new ideas, and helpful support.

The Grinch column turns into personal blaming or complaints about individual coworkers.

Step in immediately. Remind the group that The Grinch category addresses systemic blockers, bad processes, or external friction, while interpersonal feedback belongs in private 1-on-1 check-ins.
