"Mr. John Allen is one of the foremost experts in the Shainin branch of Design of Experiments (far superior to classical or Taguchi D.O.E.).  What is even more impressive about Mr. Allen is that he is a hands-on master at solving tough industrial quality and reliability problems.  He has received glowing accolades from his clients."

"John is one of a rare breed, in my experience, who has the technical acuity to see complex problems clearly, articulate the problem and a path to a solution, teach folks the required tools and coach them to realize their goal. In short, he's the technical expert's expert. In my position, I have seen few who can hold the interest of a class of 25, or a symposium of 250, as well as John."

Executive for a major motorcycle manufacturer

"John was not the first, nor has he been the last, consultant I have met during my 17 years at this company, but shortly after I got to know him, he stood out, in my opinion, as the best. In all of my time working with some truly great minds in the aerospace industry, I have never met someone with both the depth of understanding of the physical world as John, and a natural-born need to convey what he knows in simple language so that others may use that knowledge to do great things. On a technical level, John has few peers. At the same time, John stands firmly on his principles - both professionally and personally. He is an inspiration to work with, as he drives me to dig deep into problems, breaking them down into their most basic elements, solving the most important pieces of the problem first. It is a skill he has helped develop in me and, for that, I will always be grateful."

Consultant for a major aircraft engine manufacturer

"John Allen has coached dozens of successful projects for my present and previous employers, both in the chemical industry. John's remarkable ability to develop successful strategies to solve these projects has resulted in multi-millions of dollars in savings and increased revenue. Not only have I employed John's unique talents to coach technical projects, but I have found him highly effective in training management and engineers on the strategies and responsibilities required to create an effective problem-solving culture. John and I have worked together across several different countries, and his 'uncommon common sense' has international appeal". During my career, John has had the single greatest impact on my development as a technical problem solver. I have always said, when you absolutely, positively have to solve that tough technical problem, CALL JOHN!"
