“I have been very impressed with the Catalyst approach to Lean Six Sigma Training & Deployment support. They have a fun, practical, and very rigorous style of training delivery from which we all benefited. They were able to make it very real for our business and as a consequence we have delivered very impressive results from our initial waves of projects. More than this, they have provided high quality mentoring and coaching of our Master Black Belts which has given us real insights into how we can best deploy and manage the Lean Six Sigma implementation to achieve greatest impact in our complex business environment. Thank you, Catalyst, for the work you have done so far with us on what is hopefully the start of a long and productive relationship”.

South Street GP Surgery – Kai-Sigma Rapid Improvement approach focussed on improving patient experience in South Street GP Surgery, Bishop Stortford.

Multiple events with carefully managed impact on use of extremely busy surgery resources

Benefits included:

    • major reductions in patient waiting time
    • significant changes to “back office” workflow to eliminate delays and multiple hand-offs
    • Real changes to staff morale and sense of “I can make a difference”
    • Skills transfer in practical change tools

We used to have ideas but it would take months if not years to implement anything… and now we have done this in a few weeks

“There are any number of companies providing Six Sigma consultancy and training. Catalyst were unique in being able to provide material tailored to the Financial Services industry, and consultants who have relevant, practical experience that they could relate to people in different roles and at all levels. Their style is supportive, but not condescending, and they bring a touch of humour that is refreshing when considering applied statistics!”

Estelle Clark

Quality Director

“An inspiring training provider!

We had training on Lean Six Sigma Yellow Belt – a serious topic but made fun and enjoyable! I would recommend Catalyst to anyone out there for their training needs!”

Samuel Hayes

Catalyst Consulting was chosen to conduct our Lean Six Sigma Training from 3-4 other companies. I like their entire approach on understanding what we wanted to achieve from the course and how they can do this by also relating the content to our businesses. The follow through included several conversations to understand the content and logistics for the day (we were training 2 large groups). The pre-reading material arrived prior to the course with plenty of time for members to review the book. The course was delivered by Mark Jones who was fantastic as a trainer in engaging the group and delivering the content. The exercises were great and overall there were many “penny drop” moments throughout the course on what we should be doing as a business.

Omar Qamar

like the way it’s listening an interactive, extremely enjoyed the Lego experience. Really enjoyed the experience and would love to move up to Green Belt

Evelyn Campbell

(Green Belt)

“The course attracted a mix of international delegates from service and manufacturing organisations which stimulated great discussions that helped to absorb the application of Lean SS Techniques. The tutor delivered the course to an exceptionally high standard, carefully paced and with good balance between classroom and practical sessions. He was a highly experienced Master BB who had great mastery of Minitab and the ability to de-mystify the statistical side along with extensive consulting exposure. His teaching used many real life examples. He showed keen interest in each delegate and the challenges they faced in their projects offering ideas and helping to get started and build confidence. The course also included a really valuable session on the soft aspects of change management. Thank you Catalyst.”

Sue Birch

Excellent course content and extremely well delivered through the use of teaching, group discussions as well as practical and enjoyable exercises. Highly recommended.

“There is more to Six Sigma deployment than just the effective use of the tools. As a MBB deploying Six Sigma across our global business, the combination of the Healthcheck and the Masterclass course gave me a comprehensive deployment framework to align, confirm and communicate our Six Sigma strategy.”

Simon Blackett

(DFSS programme)

“Very personal and presented in a professional but relaxed manner. Sigma methodology very interesting and for me personally, pulls together many areas of my work into a more structured format. Glad that tools and template were supplied to make the course more visual. All areas of business covered and was interesting how this system works across all businesses, not just manufacturing. Great venue, especially if you are travelling from the North.”

I have recently been awarded my yellow belt and wanted to take the opportunity to say thank you to Helen Smith. Helen conducted our training back in November, following on from this I applied my learnings to projects which I regularly discussed with Helen. The lean six Sigma course has developed not only my skills, but also aided in the interaction I have with my customers. The methodical approach has generated great interest and has allowed me to access and support customers needs around improvement.

Helen has been amazing throughout my certifications, the general support and coaching she has given has made a huge difference and impact on my work. I have also started applying the Improvement process to the internal organisation, again where Helen has guided me on techniques and tools. I believe Helen is an asset to Catalyst, she is approachable, professional , methodical and a great coach…always really cheerful.

“The trainer explained relatively complicated material in a clear, simple and logical fashion using a comfortable pace. The use of hands on examples combined with the PowerPoint slides and flipchart examples works very well. Covered everything we would possibly need, plus more.”

The Catalyst Lean Six Sigma training was really excellent. Highly tailored to our needs and thought provoking. A great mix of new tools, new perspectives and guidance on practical application to help us design better solutions for our customers.”

Gary Keatings, Director

Trainers were extremely accessible and full of life experiences that drive home the point of Change Management, more so than any other course material. The materials used were quite thought provoking and original. It helped visualise the theory. Really enjoyed it, it has been great and insightful to get to know what other people are doing.

Maria Santos

Enthusiastic, knowledgeable and clear in explanations. Good variation in approach, use of examples, video’s and exercises to support theory. Quality materials to support the course – plenty of reference material to use afterwards. Great location and facilities. Excellent course overall, can’t wait to get back into the office to put it into practice!”

Very systematic – explained in clear steps with relevant exercises to put into practice what was being taught.  Set at the correct audience level – very open and honest and did not feel intimidated or embarrassed about asking questions.

Laura Whalen

Absolutely brilliant! Love the fact that no matter how many questions I ask, Mark always has a great example to explain it in a different way. His enthusiasm for the topic is second to none and really aids a productive learning environment. Mark made what potentially was a dry topic to be extremely interesting and relevant.

I Johnson,

Friendly, interactive delivery. Humorous and great explanations to all questions. Clear to follow booklet. Content structured well, despite some hard theories.

Joe Gumersall

Excellent, especially with the memory stick.

We were interested in speeding up project delivery as initial projects were taking longer than expected… …that was our original thinking, but the course has given us an awful lot more, particularly at acknowledging the deliverables

The ability of ESB Customer Supply to acquire the knowledge and skills required to improve our process optimisation approach using Six Sigma has been greatly enhanced by the professional and dedicated support we received throughout from Catalyst Consulting.

Before I participated in the course I did a bit of amateur research on Lean Six Sigma (as you do) and was of the opinion I was going to struggle through six days on what appeared to be a fairly “dry” subject.


Not a bit of it!


Marie-Helen’s delivery of the training was exceptional. She clearly has a comprehensive understanding of the subject and was able to deal easily with any of our questions. She made the subject interesting and informative by using practical examples, stories, anologies and of course a fair degree of good humour. I am certain that my own personal training experience was enhanced by having MH deliver it.


You have a real asset there…..but I suspect you know that!
