The 10 Core Structures for IT Workshops
1. 1-2-4-All — Universal Idea Generator
Time: 12 minutes. Group: Any size.
Protocol: Silent individual (1 min) → pairs (2 min) → groups of 4 (4 min) → whole group (5 min, one idea per foursome).
Discipline: Enforce the 1-minute silence before pairs speak. Without it, early talkers anchor everyone's thinking.
How to specify: Frame a single, specific question. Bad: "What do you think about testing?" Good: "What is one thing stopping your team from writing tests first?"
2. TRIZ — Surface Counterproductive Habits
Time: 35 minutes. Group: 4–7 per group.
Protocol: Three 1-2-4-All rounds:
- "What would guarantee the worst possible outcome for [main objective]?"
- "Which of those things do we currently do?"
- "What will we commit to stop doing?"
Discipline: Round 3 outputs must be "stop X" — never "start Y."
IT example (Round 1): "How would we guarantee deployments fail every Friday and trust collapses?"
3. Troika Consulting — Peer Coaching in Triads
Time: 30 minutes (three 10-minute rounds). Group: Triads.
Protocol per round: Client presents challenge (1–2 min) → clarifying questions (1–2 min) → client turns away → consultants brainstorm (4–5 min) → client turns back and names top takeaway (1–2 min). Rotate.
Non-negotiable: The client must physically turn away. This eliminates their social influence on the advice.
4. What, So What, Now What (W³) — Structured Reflection
Time: 45 minutes. Group: 5–7 per group.
| Stage | Individual | Small Group | Whole Group |
|---|---|---|---|
| WHAT? (observations only) | 1 min | 2–7 min | 2–5 min |
| SO WHAT? (patterns, hypotheses) | 1 min | 2–7 min | 2–5 min |
| NOW WHAT? (actions) | 1 min | 2–7 min | 2–5 min |
Discipline: Hold them in "So What" until at least two patterns are named. Patterns precede useful actions.
5. User Experience Fishbowl — Practitioner Knowledge Transfer
Time: 35–70 minutes. Group: Inner circle 3–7; outer circle unlimited.
Protocol: Setup (2 min) → inner circle conversation (10–25 min) → outer circle formulates questions (4 min) → Q&A (10–25 min) → W³ debrief (10–15 min).
Non-negotiable: Inner circle = direct personal experience only. No rank, no theories — stories only.
IT examples: Team who completed a microservices migration. Engineers who ran a production postmortem. Developers who adopted TDD in an existing codebase.
6. Celebrity Interview — Expert Dialogue at Scale
Time: 35–60 minutes. Group: Unlimited, theater-style.
Protocol: Interviewer frames topic (3 min) → structured interview (15–30 min) → audience generates questions via 1-2-4 on index cards (5–10 min) → interviewer asks best questions (5–10 min).
Interview arc: inspiration → challenges → what keeps you going → what do we hope happens.
Discipline: Every answer must be a concrete story, not a prepared remark.
7. Min Specs — Constraint-Based Design Thinking
Time: 35–50 minutes. Group: 4–7 per table.
Protocol: Generate must-dos and must-not-dos (6 min) → reduction test: "If violated, could we still succeed? If yes, remove it" (15 min) → repeat reduction (15 min) → cross-table consolidation (15 min).
Discipline: Elimination test is binary. If participants argue, clarify purpose and retry.
8. Impromptu Networking — Session Opener
Time: 20 minutes. Group: Any size.
Protocol: Three rounds of 4–5 minutes in rotating pairs. One challenge question + one reciprocal question per round. Example: "What challenge do you bring?" + "What do you hope to contribute?"
9. 15% Solutions — Individual Agency Activation
Time: 20 minutes. Group: 2–4 per group.
Protocol: Individual identifies actions within their own discretion, requiring no additional resources or authority (5 min) → share with group (3 min/person) → peer consultation (5–7 min/person).
Discipline: Verify each solution falls within the individual's own discretion. If it requires someone else's approval, it's not a 15% solution.
10. 25/10 Crowdsourcing — Large-Group Prioritization
Time: 30 minutes. Group: 20–500+.
Protocol: Write bold idea + first action step on index card (5 min) → cards circulate in five pass-and-score rounds, each scores 1–5 (15 min) → countdown reveal of top ten (5 min).
World Café — Cross-Pollination Protocol
Time: 2–3 hours. Group: 12 to hundreds (3–5 per table).
Session structure:
| Phase | Duration |
|---|---|
| Arrival and welcome | 15 min |
| Opening and orientation | 15 min |
| Round 1 — opening question | 20–25 min |
| Round 2 — deepening question | 20–25 min |
| Round 3 — action question | 20–25 min |
| Whole-group harvest | 20–30 min |
| Closing | 10–20 min |
Table host role: One person stays per table across all rotations, briefing new arrivals on prior rounds. This is the mechanism that creates cross-pollination — non-negotiable.
Three-question arc:
- Opening: "When have we been at our best?" (shared memory)
- Deepening: "What would it take to...?" (barriers and possibilities)
- Action: "What commitment could we make today?" (ownership)
When NOT to use: When the group needs to produce a document, reach a specific decision, or when only one correct answer exists.
Open Space Technology — Self-Organizing Format
Time: 90 minutes (mini) to 3 days. Group: 10 to 1,000+.
Hard preconditions — confirm both before committing:
- Participants have genuine passion for the central theme
- Participants are willing to take personal responsibility for what they propose
Four Principles: Whoever comes are the right people | Whatever happens is the only thing that could have | Whenever it starts is the right time | When it is over, it is over.
Law of Two Feet: If you're neither learning nor contributing, move.
| Step | Duration |
|---|---|
| Opening circle | 15–30 min |
| Marketplace (participants post topics) | 15–20 min |
| Concurrent sessions (self-organized) | 60 min – multiple days |
| Closing circle | 30–60 min |
Mini-OST (90 min): Opening circle 15 min → Marketplace 15 min → Two 20-min session slots → Closing circle 15 min. Handles 4–8 topics; 10–60 participants.
When NOT to use: Fixed curriculum, specific required conclusion, mandatory participation, or leadership already has the answer.
Gallery Walk with Parallel Workstreams
Time: 50–70 minutes. Group: 20–100+.
| Phase | Duration | Activity |
|---|---|---|
| Topic assignment | 5 min | Groups of 4–6 receive distinct topic |
| Parallel workstreams | 20–30 min | Each group produces visible artifact |
| Gallery walk | 15–20 min | All read all artifacts, add sticky comments |
| Whole-group debrief | 10–15 min | Facilitator surfaces cross-workstream patterns |
Scaling: 60+ participants requires 2–3 co-facilitators. Always assign a "reporter" role per group at 60+.
Common Workshop Strings
String A: Workshop Opener (45 min): Impromptu Networking (20) → 1-2-4-All on learning goals (12) → synthesis (13)

Failure Modes to Avoid
| Mistake | Consequence | Fix |
|---|---|---|
| Skipping silent reflection in 1-2-4-All | Dominant voices anchor all output | Enforce 1-min silence; walk around while participants write |
| TRIZ without a clear objective | Round 1 is vague; no traction | State main objective explicitly before first question |
| Wrong people in Fishbowl inner circle | Audience learns nothing real | Select by direct experience only |
| Rushing So What in W³ | Plans lack grounding | Hold So What until two patterns are named |
| OST when sponsor has a predetermined answer | Participants lose trust | Use World Café instead |
| World Café without a table host role | No cross-pollination | One person always stays per table |
| Gallery Walk without sticky-note commenting | Walk is passive | Require written comments on each chart |
Virtual/Remote Adaptation
Universal Remote Principles
- Breakout rooms replace physical sub-groups
- Miro boards replace sticky notes — use Private Mode
- Shared on-screen timer required
- Add 2-3 min buffer per protocol for breakout room management
- Reduce group sizes by 1-2 vs in-person
Protocol-Specific Adaptations
| Protocol | Virtual (Zoom + Miro) |
|---|---|
| 1-2-4-All | 1: individual Miro sticky (Private Mode ON); 2: pair breakout 3 min; 4: group breakout 5 min; All: main room synthesis |
| TRIZ | Miro frame per question; sub-groups in separate sections; synthesis in main frame |
| W³ | Miro: 3 columns; individual input (Private Mode), then group reveal |
| Impromptu Networking | Zoom: random pairs in breakout, 3 rounds of 5 min each |
| Min Specs | Miro sticky clusters: "must have" vs "must not have" in separate zones |
| UX Fishbowl | Zoom: 4-person breakout + unmute rule; outer circle stays muted |
Not Adaptable Online
- Open Space Technology (requires physical movement)
- Wise Crowds (consultation rounds lose energy remotely)
- Conversation Cafe (deep dialogue suffers from video fatigue)
