Works with Claude, ChatGPT, Gemini, or your own local model: paste this prompt and your AI will co-facilitate this exercise with you.

Help me prepare and run the exercise below. First ask for my participant count, time, setting, access needs and intended result. Check these against the stated limits. Use the supplied rules and materials. Explain any proposed changes before using them, and label them as adaptations. Do not invent source claims or require personal disclosure. Give me one step at a time when I say start. I manage the people, physical activity and clock; do not claim to observe the room. Ask me what happened before choosing a next step.

# Team Timeline

Participants map major milestones, launches, join dates, and memorable moments onto a shared chronological axis. The group reviews the collective storyline to establish common context and surface patterns.

**Time:** 20 minutes. Matches the 20-minute duration stated in source records.
**People:** 4 to 24. Independent drafting followed by whole-room clustering and silent walk or plenary review.

## Choose this exercise

**Purpose:** Construct a visible chronological map of shared milestones, transitions, and onboarding events.
**Use it when:** Use during team onboarding, project retrospectives, or annual planning to establish a shared historical record across tenure levels.
**Skip it when:** Skip when a newly formed group has no common history or when past organizational events carry unaddressed grievances that require structured mediation.

## Materials and tools

- Whiteboard or butcher paper (minimum 2 meters wide)
- Self-adhesive notes (1 pad per 4 participants)
- Fine-tip dry-erase or permanent markers (1 per person)
- Blue painter tape (for wall mounting)

## Before participants arrive

1. Draw a clear horizontal line across the center of the whiteboard or paper.
2. Label the far left with the start date (e.g., team founding or project kickoff, capped at 2 to 3 years ago).
3. Label the far right with today's date.
4. Add rough quarterly or yearly tick marks along the line.

## Say this to open

Today we will map our shared history. We have drawn a timeline running from our start point to today. You will write key moments on sticky notes and place them along the line. If you joined recently, write your join date, your initial observations, and any major events you have seen so far.

## How to run it

### 1. Introduce timeline and silent note writing (4 minutes)

State the start and end dates on the timeline. Give participants sticky notes and markers. Ask everyone to silently write 2 to 4 distinct events on separate notes. Events can include product launches, hiring dates, office moves, pivots, or humorous team memories. Newer members write their arrival date and an early impression. Example note: 'Joined team, March 2024 - first all-hands meeting.'

### 2. Post notes chronologically (5 minutes)

Invite participants to approach the board and stick their notes in approximate chronological order above or below the line. Participants place items without detailed presentation to keep movement steady. If multiple notes refer to the same event, group them together vertically.

### 3. Chronological walk and pattern review (6 minutes)

Ask participants to stand near the board or review the full wall. Walk left to right along the timeline, reading key clusters aloud. Invite brief clarifications on items that might be unfamiliar to newer members. Keep individual remarks under thirty seconds.

### 4. Debrief and note preservation (5 minutes)

Facilitate a short group debrief using the planned questions. Take two or three contributions per question. Photograph the board to document the record for team files.


## Debrief questions

- Looking across this timeline, where do we see high clusters of activity versus quieter periods?
- What important turning points or breakthroughs helped establish how we work today?
- What routines, traditions, or habits shown on this timeline do we want to carry forward?

**Finished output:** A chronological wall map of team milestones, hires, and pivotal moments, documented via photograph or shared digital board.

## Remote

Create an online whiteboard (such as Miro or Mural) with a pre-drawn horizontal line labeled with start and current dates. Set a 4-minute timer for silent sticky note creation. Instruct participants to drag notes to the line simultaneously. Conduct the chronological walk-through using screen share while participants highlight or comment on specific notes.

## Hybrid

In a hybrid setup, use a digital whiteboard as the single source of truth. In-room members access the board via laptops or designate a room scribe to transcribe physical notes immediately. The shared digital board is projected on the main room screen so all participants view the exact same chronological updates in real time.

## Access and participation choices

- Participants may decline to share personal milestones and focus strictly on public organizational dates.
- Participants may contribute via spoken input to a scribe instead of writing or physically walking to the board.
- Full participation does not require speaking to the entire room; placing a note or observing silently fulfills the activity.

## If the session gets stuck

**Newer team members feel excluded because they were not present for early milestones.**

Explicitly invite newcomers to post notes for their first week, their onboarding impressions, and observations of the current culture. Direct early questions to what surprised them.

**Participants cluster excessively around recent events, leaving the early timeline blank.**

Acknowledge that recency bias is normal. Ask if anyone present remembers the early foundation period and can add one or two orienting anchor dates.


## Terms used here

- Anchor date: A known fixed date, such as a company founding or product launch, used to orient other memories on a timeline.

## Sources and adaptation

Observed on Icebreaker-Games.org (Team Timeline). Original authorship is not stated in the evidence.

Retained the core mechanic from Icebreaker-Games.org: drawing a horizontal timeline on a whiteboard, posting milestone notes, and using newcomer join dates to orient new hires. UWT added exact stage timings summing to 20 minutes, explicit material requirements, hybrid procedures, access options, and structured debrief questions.
