We can help you with:

Diagnostic - ‘How human is your organisation?’

Thompson Harrison, in partnership with Oxford University’s Professor Robin Dunbar, has designed an organisational diagnostic that gets to the heart of the very human experience within an organisation. 

Problem Solving using Organisational Constellations (Systemic Mapping)

Constellations or Systemic Mapping is a simple way of discovering the hidden dynamics that exist in an organisation, by using a diagnostic that shines a new light on old problems. This approach is a visual and participative way of engaging in systems thinking. It provides a different perspective and insight by working with the dynamics and energy in the system itself.

The Rethink Tank

The Rethink Tank is an immersive experience for senior leaders to find the time and place to step back together,
to share a collective pause and to reconnect with their prime purpose. It broadens frames of reference and through shared learning, builds trust and leads to a new collective approach to tackling the most stymieing of challenges facing the organisation.

Digital Capability Building

Thompson Harrison works with large organisations to develop senior leaders - focusing on individual behaviour change and organisational culture change required in the digital context.


Working alongside change agents within an organisation, Thompson Harrison will develop the in-house capability needed to continue changing and evolving. This maintenance work is essential to sustainable leadership development.

Leadership Development Strategy and Framework

Organisations are continuously under pressure to adjust, refresh and update their leadership development strategy and framework to meet current and future business needs. The greatest challenge for leadership development in any organisation is to remain relevant and responsive. Thompson Harrison partners with organisations to build agile leadership development frameworks.

Leadership Styles

Sam, Tracey and the TH team have been with us the last couple of years on the journey of redefining what we needed in the leadership development space, at all levels. What makes them different is they really listen, they really probe and they are really willing and able to tailor interventions and programs as a consequence. Personally, I have enjoyed and benefitted from their charismatic but pointed challenge to perceived ways of thinking and as an organisation I can already see that we have grown in the development space - fast and slow. Fast in terms of engaging in a world where future trends become todays’ reality overnight and slow, in giving our leaders the time and space to take time to reflect on themselves, their journey and the world around them.
— Paolo Lanzarotti, CEO Asahi Beverages Europe Group

Tracey and Sam together are able to design ways for senior leaders to think about the future in new and unimagined ways and then to work with them to get their organisation into that place. Their sweet spot is helping leaders make sense of a complex world by exposing them to leading thinkers and ideas and then focusing on the pragmatic implementation of these ideas. Their approach is invigorating and fresh and stands out from traditional leadership programmes.
— Annabelle de Groot, AB Inbev Business Unit President, West Africa
Tracey is highly skilled in building bespoke leadership programmes using her extensive experience and knowledge in this field. The passion, energy and fresh thinking she provides to both individuals and companies during their leadership journey is a refreshing change. Her style is engaging and personable but she is not afraid to challenge the status quo. I would highly recommend working with Tracey.
