The team report

One assessment, fifteen ways to read your team.

Every team report opens with the Team Compass — eight roles on one wheel — and goes deep on communication, conflict, stress, leadership, decision-making and the pairs that make or break collaboration.

Reports update automatically as the team changes — plus an insights tab where an AI assistant, grounded in your team's actual results, answers follow-up questions.

Team & leadership

Lead each person the way they want to be led.

JTI gives leaders, HR partners and coaches a shared vocabulary for how different people think, decide, and respond to pressure.

Compose better teams

See where your team has range, where it's narrow, and which conversations to start before tensions appear.

Speak to who is listening

Adapt your message to how each person prefers to take in information and make decisions.

Defuse conflict early

Most team conflict comes down to type difference, not personality. The reports name the patterns and what to do about them.

Personal development

Become more of who you already are.

Type isn't a box you fit into. It's a description of preferences you already have, written down in a way you can work with.

Self-awareness, plainly described

Your preferences for taking in information and making decisions, in language you'd use yourself.

Your less-developed sides

The parts of you that are quieter than the rest, and how to bring them on as you need them.

A direction, not a label

Use your type as a starting point for the next decision or conversation. It's not a fixed verdict, and it can develop with you.

Type reports & booklets

Reports people actually read.

Every participant gets a long-form description of their type — strengths, growth areas, communication style, stress patterns — on screen, as a PDF, and as booklets you can put on the table in a workshop.

Why JTI

What makes JTI different

There is no shortage of type indicators. JTI is one of very few that has been independently validated and stays close to Jung's original work.

Validated by an independent body

DNV (Det Norske Veritas), a global independent assurance and certification body, validates JTI's psychometric properties.

Grounded in Jung's original typology

Built on Carl Jung's original typology, with the language modernised for today.

A complete practitioner toolkit

Assessment, reports, team analysis, booklets and certification live in one platform — from a single debrief to a full team programme.

In use for over two decades

Used by HR teams, leadership programmes, and coaches across Europe for over twenty years.

“For 20 years I've used JTI in my career-change programmes, and over 11,000 people have found their right path. The most powerful moment is when someone realises they hadn't been failing because they weren't capable enough — but because the work didn't match their natural preferences.”
