Our Founders

Back in 2007, the WhyNot brand was born out of a commitment to constantly create the latest thinking and practice for organisational design and safety – to enable people to have the opportunity to thrive at work. It actually started in Simon Marshall’s garage in deepest Gloucestershire, England. He and his lifelong friend, Peter Docker, spent many weekends covering the walls with flip chart paper and barely legible scrawling as they recorded the things they had learned over their careers about how people communicate and work together. Gradually they distilled their thinking into what was to become the building blocks of WhyNot Un Limited, a company that is now a vehicle for Peter engaging many thousands of people a year in these new ideas and concepts, by speaking and running impactful workshops all over the world.

Soon afterwards and in more comfortable surroundings, (Simon’s conservatory) Sally Caruana and Simon joined up to create WhyNot Partnering Ltd. WhyNot Partnering (now known simply as WhyNot) is committed to transforming the nature of work, by partnering with organisations who want to implement these ideas inside their business. Sally and Simon came together with a shared belief that there’s a better way for businesses to work. A way that enables everyone to be their authentic selves, be fully self-expressed, and really know how their work contributes to the higher purpose of the organisation. When this and other leadership attributes are in place, everyone’s full potential gets released. The inevitable outcome of this is high performance.

Sally and Simon are the authors of WhyNot’s transformational approach, Why-Based Organisational Development and Why-Based Safety, which enable organisations and major projects to create extraordinary performance, by engaging people in deeper ways – effectively bring a deeper level of human connection to business.

Let’s talk

Responding to COVID-19

We’re continuing to support all our clients during these uncertain times, as they navigate through the various challenges facing their organisations. Generally our work is about supporting people to take on new challenges and building the capability to lead when you don’t know the answer - and through this crisis we’re enabling our clients to do this from a place of care. Something is happening during these times that resonates with us on a deeply human level. It has made us realise how closely we are all connected and how new levels of trust, empathy and caring for one another must be part of how we organise ourselves moving forwards.

We’ve been gathering learnings, building on our experience and we’d be happy to share these with you. We are supporting many other leaders as they think through how to ‘re-generate’ their businesses and create the next version of themselves based on what matters most.               

Over the next few weeks you will see our COVID-19 Resource Centre on Our Insights page offering our latest learnings and thinking. If you’d like to explore our approach further, we’d be happy to have an informal chat.

Stay safe, The WhyNot Team
