Who the Complete Development System is for?

Most coaching creates insights. But few approaches consistently translate that insight into measurable behavioural change. The Complete Development System is designed for coaches who want to close that gap.

Coaches who want to move beyond intuition to a more structured, evidence-based approach. Who are looking to differentiate their offer in a crowded market. And who want to build a more scalable, assessment-led coaching model while deepening the quality and consistency of their client work.

Values for Leaders

Many leadership and coaching interventions improve awareness but struggle to translate that into sustained behavioural change, because the insights won’t tell you what drives behaviour.​

The Values for Leaders Certification addresses that directly. Backed by over 50 years of academic research, the Complete Values Profile provides a precise view of the value systems shaping how people think, feel, and act. So you can deliver more effective, development-led interventions.​

This is not theoretical learning, but a practical, applied approach. Using the Complete Values Profile. You will work with a clear, repeatable framework in real contexts. So your insights and coaching can translate into consistent, measurable change.

Transformations in their own words

Clients share how their journey through vertical development and leadership growth empowered them to grow and make an impact.

"Alan is a world-class coach and I've worked with him for over 3 years. As well as being a wonderful listener with exceptional recall and having a very supportive style, he is also not afraid to challenge. When he does challenge, he does so really thoughtfully and constructively.

With his considerable expertise in human behaviour, mindfulness and psychology, he has helped me not only become more effective in a work context but he has also improved the quality of my life."

Anthony Burrows

Founder, Intelligent Emotion

 “No doubt Alan [Littlefield] has done a lot of research and understands a lot of concepts and models which have been useful in our coaching. ... Highly competent, professional services firm with strong evidence of EI and practical insights.”

Des Moore

CEO, CBS

"As a coach, he [Alan Littlefield]  is quick to put you at ease and his ability to help you get to the crux of your issue and a solution is second to none. I have the utmost regard for Alan's coaching capability and professionalism and would recommend Alan wholeheartedly for anyone seeking an executive and knowledgeable coach"

Rob S

Tesco

“Alan [Littlefield] is very experienced... I don’t think I have ever felt so comfortable sharing personal stuff with someone for as long as I can remember.

I felt that I could talk to him about anything and that everything would be safe – very high degree of trust on my side which is not something I do very easily, hardly ever."

Dirk Geeraerts

VP Sales EMEA, Thales Belgium

"Alan's passion for coaching and commitment to quality have been obvious to me since the first time I met him. We worked together at the Centre for High Performance Development for 3 years, and during that time, I had the opportunity to see him coach, to attend advanced coach training that he developed and delivered, and to use the coaching engagement process he created for CHPD's use with clients."

Susan Salomone

Healthcare

"I worked with Alan at Kenexa and was extremely impressed by his passion and expertise of coaching. With his warm and professional disposition and exceptional interpersonal skills, Alan proved to be a real advocate for coaching across Kenexa and always had an open door policy with anyone that had an interest in the subject.

I attended the Coaching skills course that Alan designed and conducted and found this to be fun, informative and more importantly it helped to develop and enhance my skills as a Coach"

Ruhina O'Boyle

 

"I have had the pleasure to work with Alan [Littlefield] on a number of occasions with Tesco and each interaction has been a delight and a pleasure. Alan's understanding of Tesco and retail is second to none, and makes the development come alive. He is a fantastic facilitator and generous with his knowledge and learnings."

Rob S

Tesco

"Alan was my coach and trainer in Advanced Coaching techniques during a Senior Leadership Development programme for NMSI. He is wonderful to work with and always helped me to arrive at a solution with humour, sensitivity and intelligent thinking. He has become a friend and confidante and I have great pleasure in recommending him."

Sue Dewey

OBE Director

"Alan's coaching and coach training are second to none, and I still refer to the process he created on a regular basis. I have worked with other executive coaches since leaving CHPD and have not found anyone whose process is as thoughtful or as thorough as the approach that Alan crafted. For me, it has become the gold standard."
