Why it matters

Safety is the mechanism. Performance is the outcome.

Team psychological safety is "a shared belief that the team is safe for interpersonal risk-taking" (Edmondson, 1999). In practice, that means people speak up early, ask for help, surface problems while they are still small, and take the creative risks that innovation requires.

Teams that have it learn faster, retain their people longer, and consistently outperform teams that do not. Teams without it stay quiet, and quiet teams are expensive.

When teams feel safe, they do remarkable things.

A team working closely together
The framework

Seven elements you can measure and build

Team psychological safety is built, rather than wished for. The TPS model gives you seven observable elements, each one you can assess, benchmark, and develop, resting on five foundations and driving team learning and performance.

The Team Psychological Safety model: seven elements as pillars (reaction to mistakes, dealing with issues, embracing diversity, taking risks, asking for help, mutual support, appreciation) supporting team learning and team performance, resting on five foundations
01

Reaction to Mistakes

Mistakes become learning, rather than blame.

02

Asking for Help

Support without looking incompetent.

03

Appreciation

Contributions are seen and valued.

04

Embracing Diversity

Different perspectives are welcomed.

05

Dealing with Issues

Tensions get addressed, rather than avoided.

06

Taking Risks

Bold ideas without fear of ridicule.

07

Mutual Support

A team that looks out for its own.

Each element is measured by the TPS assessment: a confidential team survey producing a 25-page benchmarked report.

Bundle · TPS + LEGO® Serious Play®

Measure it with TPS. Create the conditions for it with LEGO® Serious Play®.

The TPS assessment shows a team where psychological safety is strong and where it is thin. The next question is what to do in the room. The LEGO® Serious Play® method is one of the most practical answers we know.

In a LEGO® Serious Play® session every person builds a model of their answer and every person explains it. The quietest member of the team has the same time and the same attention as the most senior. People speak through what they have built, which makes a hard subject easier to put on the table, and increases the potential level of team psychological safety.

Dealing with issues

A model gives a team something concrete to point at when a problem has been talked around for months.

Embracing diversity

Every perspective is on the table at once, built and visible, before anyone has argued for it. It works particularly well for introverted and neurodivergent people: everyone gets time to think before they speak, and the answer is focused on an external model rather than on the individual.

Taking risks

A half-formed idea is easier to offer as a few bricks than as a finished proposal.

And it reaches well beyond psychological safety. Practitioners use LEGO® Serious Play® for:

Strategy and visionTeam developmentOnboardingInnovation and ideationRetrospectivesChange and transitionsStakeholder engagementCoaching
Why take both
  • Diagnose, then act. TPS shows you where a team stands. LEGO® Serious Play® gives you a way to run the conversation that follows.

  • Two certifications, one price. $1,400 off the full price of both, and $500 off the two early-bird rates.
  • Your order. Take the two-day LEGO® Serious Play® certification in Vancouver before or after your TPS modules.

Questions

Frequently asked

Four sessions of 3.5 hours each: modules 1 and 4 on Zoom, modules 2 and 3 in person in Vancouver, all on Pacific time. Between modules 3 and 4 you work in a small group on a real case and develop an intervention approach, and module 4 is where that comes back. There will be some pre-reading prior to each module.

Not this cohort. Modules 2 and 3 are in the room, so you need to be in Vancouver on the afternoon of Friday, November 20 and the morning of Saturday, November 21. The next cohort runs fully online. Leave your details below and we will send you the dates as soon as they are set.

It connects directly to psychological health at work, and it is a team-level performance construct from organizational research, about interpersonal risk-taking and team learning. You will learn to measure it and connect it to both wellbeing and performance outcomes.

You leave with a licensed capability, rather than only learning: the TPS assessment licence, a benchmarked team report included, a practitioner toolkit you can deploy across teams immediately, and a copy of Peter Cauwelier’s book, Your Untapped Team Advantage Toolbox.

No. The program is designed for HR professionals, wellbeing and safety leaders, coaches, team leaders, and consultants alike. Every element is taught from the ground up.

It is possible to miss one of the Zoom sessions and to watch the video afterwards. However, we ask that you be present for both the in-person sessions on Friday afternoon and Saturday morning.
