Team Self-Selection Workshops

---

Origins

Team self-selection was popularized by Sandy Mamoli and David Mole in their book Creating Great Teams (2015), drawing on practice at Trade Me in New Zealand and dozens of other organizations.¹ The technique addresses one of the most disruptive moments in scaling: when an organization needs to reorganize teams, and the conventional response is for managers to assign people to new teams from the top down.

Self-selection inverts the move. The organization defines the teams, the missions, and the constraints. The people then choose which team they want to be on. Constraints prevent the choice from producing infeasible outcomes; everything else is up to the participants.

The Workshop Format

A typical self-selection workshop runs in a single half-day to full-day event. The pattern:

1. Prepare the teams (advance work)

Leadership defines the team set: which teams will exist after the reorg, what each is for, what success looks like. The teams are presented at the workshop; they are not negotiable.

2. Define constraints (advance work)

Constraints encode the must-haves: minimum and maximum team size, required skills per team, restrictions on who can be on certain teams (e.g., security clearances). These are non-negotiable.

3. Open the marketplace (workshop)

Participants are physically presented with the team options — typically large posters or tables labeled by team. Participants choose where to go, signaled by physically standing with that team or placing a sticky.

4. Iterate (workshop)

Multiple rounds. The first round usually produces violations of constraints — too many people for one team, missing skills on another. Participants negotiate, move, and trade until all constraints are satisfied.

5. Confirm (workshop close)

Once all constraints are met, the teams are confirmed. Participants commit. The new structure goes into effect on a defined date.

Why It Works

• Ownership. People who chose their team are more committed to it than people who were assigned.
• Information surfacing. The negotiation reveals preferences, fears, and capabilities that top-down planning would never have seen.
• Cultural signal. The workshop says explicitly that the organization trusts its people to make this decision. The signal compounds over time.
• Better matches. People often know better than their managers which work they would thrive on. Self-selection captures that knowledge.
• Time efficiency. The whole reorg happens in one day, not over weeks of management discussions.

What Makes It Hard

• Leadership trust. Managers must genuinely accept whatever the workshop produces. If decisions can be overridden afterward, the workshop is theatre.
• Strong personalities. Charismatic or senior people can pull weaker colleagues to their team, distorting the selection. Facilitation must address this.
• Constraint design. Too few constraints produce infeasible teams; too many constraints make the choice illusory. Calibration matters.
• Hidden interpersonal dynamics. People may avoid teams because of specific colleagues. The workshop format can surface this awkwardly.
• Unequal team appeal. Some teams' work is more attractive than others. Self-selection can produce empty unpopular teams.

Variations

• Two-stage self-selection. Round 1 lets people indicate preferences; round 2 finalizes after constraint adjustments. Reduces pressure of single-shot choice.
• Manager-facilitated. Managers help interpret constraints and answer questions but don't make assignments. Common in larger organizations.
• Periodic re-selection. Some organizations run self-selection annually or semi-annually. Teams persist for a defined period, then participants choose again.
• Constrained self-selection. Used when the organization has hard requirements that can't be left to chance. Strong constraints; soft selection within them.

When Self-Selection Earns Its Keep

• Reorganizations involving 20–200 people. Below 20, conversations work. Above 200, the workshop logistics get complex.
• Cultures with reasonable psychological safety. Without it, people don't trust the process.
• Leadership genuinely willing to honor the outcome.
• Organizations transitioning to more agile structures, where the choice signals the cultural shift.

When It Doesn't Fit

• Highly regulated environments where role assignments are constrained by compliance.
• Organizations where leadership cannot accept the workshop's outcomes.
• Cultures with strong hierarchical norms that make voluntary choice awkward.
• Reorganizations driven by performance management (i.e., quietly removing people).

Coaching Tips

Get leadership commitment in writing.

The workshop fails if leadership reverses outcomes afterward. Make the commitment explicit and public.

Design constraints carefully.

Skill requirements, team size bands, can't-be-on-this-team rules. The constraints shape the realistic outcome space.

Run a dry run with the leadership team.

Before opening to the org, let leaders self-select among their leadership-equivalent options. Surfaces facilitation issues cheaply.

Watch for charismatic anchoring.

Strong personalities can pull others. Use silent first rounds (private sticky placement) to dampen the effect.

Address unequal appeal explicitly.

Some teams' missions are less attractive. Name this upfront and address it with explicit recognition.

Plan the next iteration.

Teams formed today are not permanent. Naming when the next self-selection will happen prevents the current choice from feeling locked in forever.

Summary

Team self-selection is one of the boldest moves available to organizations facing a reorganization. By letting people choose their own teams within constraints, it produces better matches, stronger ownership, and a cultural signal of trust that compounds over time. The technique requires real leadership commitment — to accept whatever the workshop produces, to design constraints carefully, and to facilitate honestly. Where those conditions exist, self-selection is dramatically better than top-down assignment. Where they don't, the workshop is just theatre.
