The trademarked framework

A shared language for behaviour, not personality.

The Red Flags Green Flags® framework translates behavioural psychology into an observable-outcomes approach. Rather than labelling people, it helps individuals and organisations identify what people actually do, understand the effect of those behaviours and decide what needs to be addressed, interrupted or strengthened.

Developed by Dr. Ali Fenwick and brought to a global audience through his best-selling book, this trademarked approach tackles behaviour at its core: the patterns, triggers, consequences and choices that shape healthy and unhealthy relationships.

One framework, four settings.

In yourself

Notice your own patterns under stress, and the habits worth reinforcing.

In a relationship

Read early signs in dating and partnerships before you’re deeply invested.

In a team

Spot the dynamics that quietly undermine trust and psychological safety.

At work

Give leadership and HR a shared, behaviour-based vocabulary to improve how people treat each other at work.

Training, workshops & tools

Make behaviour visible, discussable and changeable.

Red Flags Green Flags® training gives organisations a practical language for identifying healthy and unhealthy behaviour without reducing people to labels. Sessions are engaging, evidence-based and designed around the real behavioural challenges facing your teams.

Questions & answers

About the Red Flags Green Flags® framework.

What is the Red Flags Green Flags® framework?

It is a behaviour-based framework developed by Dr. Ali Fenwick that helps people recognise observable healthy and unhealthy patterns, understand their impact and decide what to address, interrupt or strengthen in relationships, workplaces and everyday life.

Is the framework a form of therapy?

No. The framework is an educational and behavioural methodology, not a substitute for psychotherapy, diagnosis or mental-health treatment. Qualified practitioners may integrate approved tools within their existing professional work and scope of practice.

How is the professional programme different from the book?

The book introduces the framework for everyday use. Professional training goes further by teaching the methodology, observable-outcomes approach, facilitation skills, assessment tools and structured resources needed for responsible delivery with clients, groups or organisations.

Can the framework be tailored to an organisation?

Yes. Keynotes, workshops and programmes can be adapted to your culture, goals and audience, helping teams develop a shared behavioural vocabulary for healthier relationships, leadership, trust, psychological safety and collaboration.

Who can become a certified or licensed practitioner?

Pathways are designed for eligible psychologists, psychotherapists, counsellors, coaches, educators, healthcare and well-being professionals. Admission and permitted use depend on professional background, completed training and the applicable licence terms.
