Enneagram

The Enneagram describes 9 personality structures rooted in deep motivations, fundamental fears and defence mechanisms. It's the tool of choice for development coaches who want to work in depth on self-awareness and lasting change.

Category Deep motivations and character structure (a typological model with 9 profiles)

Average cost Free (self-assessment) to paid depending on publisher (the Enneagram Institute's RHETI, iEQ9...)

Certification required Not mandatory — in-depth training strongly recommended for the debrief

When to use it

Where it applies

→Recruitment. Not recommended for direct selection (insufficient predictive validity). Can be used in onboarding to ease integration and mutual understanding within a team.
→One-to-one coaching. Its natural home. The Enneagram lets you work on automatic patterns, reactions under stress and unconscious needs. Ideal for leadership-development or personal-transformation coaching.
→Team-building & management. Powerful for building empathy and awareness of blind spots across a team. Enneagram workshops are often strong moments of collective realisation.

The underlying model

How the model works

The Enneagram is a dynamic model: it doesn't just describe who you are, but how you evolve, how you react under stress, and how you access your best self. Each type belongs to one of 3 energy centres that define its fundamental relationship to the world.

8·9·1Instinctive centre (the Gut). Relationship to anger, control, autonomy. Fundamental question: "Do I have the right to exist and to act?"
2·3·4Emotional centre (the Heart). Relationship to shame, self-image, personal worth. Fundamental question: "Am I loved, and am I of value?"
5·6·7Mental centre (the Head). Relationship to fear, security, certainty. Fundamental question: "Am I safe, and do I have enough?"

The 9 types

Type 1 — The Reformer

Motivation: to do things right, to be good. Fear: being corrupt or flawed.

Type 2 — The Helper

Motivation: to be loved and needed by others. Fear: being unwanted.

Type 3 — The Achiever

Motivation: to succeed, to be admired and recognised. Fear: being worthless.

Type 4 — The Individualist

Motivation: to be unique, to find one's deep identity. Fear: being ordinary.

Type 5 — The Investigator

Motivation: to understand the world, to be competent. Fear: being overwhelmed or incompetent.

Type 6 — The Loyalist

Motivation: to find security, to be supported. Fear: being without support, abandoned.

Type 7 — The Enthusiast

Motivation: to live fully, to stay free. Fear: being deprived, missing out on something vital.

Type 8 — The Challenger

Motivation: to be strong, to protect one's own. Fear: being controlled, vulnerable.

Type 9 — The Peacemaker

Motivation: to maintain inner and outer peace. Fear: separation, conflict.

Every type carries two dynamic arrows: a stress arrow (taking on the negative traits of another type under pressure) and a security arrow (accessing the positive traits of another type when doing well) — a valuable dimension in coaching for understanding regressions and grounding strategies.

Wrap-up

Strengths and limits

Strengths

✓Unique depth for understanding unconscious motivations and repeating behaviour patterns.
✓A transformational tool: it works on "why I do this" rather than just "how I behave".
✓Very engaging for coachees looking for a deep understanding of themselves.

Limits and biases

✕Determining the type is tricky: questionnaires alone aren't enough — a typing interview is often needed.
✕Psychometric validity is still debated — use it as an exploration tool, not as absolute truth.
✕Requires serious training to avoid reductive or hurtful interpretations.
