Client Testimonials



I had the great privilege of working for Dr John in my very early days as a Manager whilst working for DS Smith. His skills are varied but his ability to problem solve and remove barriers were at the forefront for me. John is a very inspirational man to work with and for, he takes great pride in developing businesses as well as the people within, or as John would say – ‘ your greatest asset’ His improvement strategies and tools have stayed with me throughout my career as they have with others. I would recommend Dr John in a heartbeat, he always delivers in his own unique and charismatic way.

Mr. Colin Preece

Director of Operations, Pristine Condition Ltd

“We’re working closely with John on OEE and Lean manufacturing principles, helping us covert our enthusiasm and OEE naivety into processes that release the potential of our equipment, processes and people. John’s wealth of manufacturing experience is apparent and his guidance is clear, logical and forward thinking; precisely our direction of travel.”

Mr. Simon Nurse

Works Manager, Capital Topco Plc

“John was very helpful in teasing out the assumptions in the process and his continued questions raised important issue that will need to be dealt with by the relevant professionals in our team.

The FMEA that was carried out was able to highlight several strengths and weaknesses in the design process and now that we are aware of those we will be able to dedicate time and energy to specific goals.”

Dr Alvin Orbaek White

“As I have moved from business to business I have always used John to introduce 5S and other World Class Manufacturing techniques. John has the ability to explain the concepts in an easy to understand manner, usually aided with photos and real life examples. John’s approach is very practical and I have always seen immediate results. On repeat visits John has always kept himself updated and it’s a real advantage having John’s experience to learn from. My operations managers usually can’t wait for the next tips and ideas. For anyone at any level looking for the next efficiency improvement, I would have no hesitation to recommend John”

I have known John Thomas for over 20 years and have worked with him as a colleague and also as a customer. John has a comprehensive knowledge of the tools and techniques of a variety of Continuous Improvement methodologies and is comfortable working with people throughout an organisation from boardroom to shop floor.
John’s ability to translate the sometimes opaque academic speak used in some of these methodologies into common sense, practical actions which can make a huge difference to performance have helped him to build up an impressive track record with his customers, many of whom have worked with him over a long period of time.
In addition to being able to make a real impact, John’s affable personality helps him to fit in quickly into the teams he works with.
I would have no hesitation in recommending John to help a business to move forward to a brighter and more successful future.

We started working with John Thomas 4 months ago & are already beginning to bear the benefits from sessions we have had with regards to increased productivity & waste reduction. His enthusiastic and simple terminology has been key to the successfully sign on by all our employees – giving empowerment to the operators we have seen changes come from within the groups. We are looking forward to further sessions where we will be targeting specific areas.

Mr. Alex Mulvenny

Managing Director , Labelgraphics, Glasgow:

Having worked with Dr John previously at another company, there was only one person to turn to when I was asked to arrange a Project Management course for our Management Team.  Dr John’s training is so unique, due to his exceptional level of experience, plus there was an added bonus, as Dr. Rhian Thomas co-delivered the course too!

Our management team came armed with their ‘projects’ ready to apply the techniques clearly demonstrated by Dr John and Rhian over 3 separate sessions.

From the very first session, we instantly witnessed the impact the Project Management training was having on the team’s KPI’s.  We observed reductions in departmental overheads; refined internal processes; improved confidence levels in the management team; teambuilding; collaboration; and the entire management team came away speaking a new ‘project management’ language.

The benefits have been immense, so thanks Dr John and Rhian for delivering an exceptional course which is adding so much value to our business as a whole
