“I found The GC Index session that we had extremely interesting – it allowed me to identify my own personal preferences and strengths, as well as those of my team. The facilitator, Andrew, was excellent and really helped to bring the written reports to life. He helped us to focus on understanding how our personal and team profiles can be used to help improve our overall business performance.”

“Without doubt The GC Index® is the most comprehensive framework I’ve used to help individuals, teams and organisations understand how they make an impact in the workplace. It is so simple to use and easy to apply, which makes it accessible and meaningful to everyone.
“If you are going to influence the culture and behaviours of an organisation through a fundamental business transformation programme the behaviour and ways of being that the transformation team exhibit themselves are important, as is the balance of that team’s workstyle preferences. The GC Index® provides a practical framework to assess this and more importantly help transformation teams accelerate their business impact.”

“The GC Index was effective at a critical time when we created a new team post-acquisition. Our associates were able to identify their roles, bond over similarities, and discover areas for collaboration. The group profiles were also instrumental in defining the needs of the overall organization and potential growth opportunities.”
Daphne Tan VP of Head of Development Planning at Marriott Hotels
“The GC Index® adds real value to teams that use it by giving them the opportunity to consider their strengths and how they might best deploy them to be successful. It provides personal and shared insight into how they make their impact and allows them to select roles and tasks that are best suited to their strengths. With four of the top five teams at this year’s LA Challenge being powered by the GC Index® the results speak for themselves!”
Marianne Douglas Senior Leadership and OD Business Partner at West Midlands Employers

 “The game-changing challenge was a fantastic way to get new input and perspectives to our challenge from a diverse group of individuals. The radical process students went through to understand the challenge and come up with ideas that was really interesting – this has helped us question ourselves and look at things from a very different perspective.”
Peter Markussen Senior Manager at Energinet
“The game-changing talent competition worked perfectly. By changing the value chain from ‘Producer to Consumer’ to ‘Consumer to Producer’ students got to understand what XTN is very quickly. Structuring the challenge in this way meant they came up with some incredibly creative solutions as to how we can reach the consumers, which we will be exploring.”
Bjørn Bekkevold Founder & CEO at XTN Group Holding

COO Global Project Management Consultancy
“My boss was amazing – she put me forward to work on interesting projects and knew exactly where I could add value. She gave me the freedom to work how I wanted and didn’t stifle me with unnecessary questions.”
Game Changer Professional Services Partnership
“They said they wanted someone who was creative and could drive innovation. I quickly realised this was not the case – the board just wanted us to do as we were told. But this was having no impact so I had to leave.”
Director of a small business
“We didn’t have any hard and fast rules in our family. The only rules we had were to have good manners and be considerate.”
Game Changer. Local Government
“I lost heart and felt claustrophobic, so I left corporate life and set up on my own. There was too much red tape, too many barriers and too many people ready to dismiss my ideas without listening to them.”
Game Changer & Entrepreneur
“I have always been called ‘disruptive’ from school through to my working life. I find the ‘disruptive’ moniker very negative and not something I can relate to. This Game Changer movement has answered many questions that I have wrestled with about myself and how I can impact a team or organisation.”
Game Changer Telecoms Sector
“Being a Game Changer can be a lonely place. I often felt out of place – like I was being judged. Quite often it felt like colleagues had formed an opinion of me before they’d even met me.”
Marketing Executive
“Honestly – I feel less of an idiot after reading both reports. I have genuinely been frustrated with my ‘skill set’ for as long as I can remember – I have always found it impossible to explain how I feel to myself or others. This report makes me feel like I do have a role.”

The GC Index is a valuable tool. We have used a number of other assessment tools but the GC Index offers something unique and it is easy to apply in the workplace.

“Out of any assessment I have ever done, this is the one I feel is the MOST like I actually am….”
Careers Advisor
“I was feeling exhausted and disillusioned at work but The GC Index has given me the tools to take charge of my own game and empowered me to start shaping the future career I want, rather than the one I have fallen into. It’s given me the confidence to stop trying to be something I’m not and to start focusing on my strengths.”
