Brad Jones' phenomenal career in DOE

Distinguished Research Fellow Bradley Jones will be retiring July 31 after an amazing 25-year career at JMP. In that time, Brad built a strong DOE development group, and probably the most prolific patent-awarded group at SAS. Below, you can read a historical tribute by John Sall on Brad's work, collaborations, and contributions to the world of design of experiments (DOE) and statistics. 

But first, a few words from some of Brad's special JMP colleagues and statistically minded friends: 

 

Mark Bailey (@Mark_Bailey): "I started working in SAS Education just a few months after Brad joined JMP Development. Custom Design was several years yet to come with the launch of JMP 4. We quickly became allies in helping scientists and engineers use designed experiments to learn by changing the design to suit their problem instead of the other way around. We met often to exchange experiences and ideas. It is hard to imagine now how strong an opinion was against the algorithmic or optimal design approach, especially among leading DOE thinkers. I attended a short course taught by Doug Montgomery at a Fall Technical Conference. Doug was disparaging toward such designs in general, and JMP in particular. I shared Doug's opinion with Brad after returning from the course, and he decided to meet Doug. The rest is DOE history. This example epitomizes Brad: always a principled approach, turning adversaries into colleagues and proponents while advancing a practical solution that benefits as many people as possible."

Peter Goos: "Bradley Jones was a highly influential researcher, with a large impact on the state-of-the-art and the state-of-practice in design of experiments, with more publications in highly regarded academic journals than many academics. I believe that the two papers with the biggest impact were one on Bayesian D-optimal designs and the one on definitive screening designs. Another influential publication is, of course, the Goos-Jones book “Optimal Design of Experiments: A Case Study Approach”. What I also observed on many occasions is that Brad was adored by the DOE users among the JMP customers. On a different note, during a joint run in Seattle (on the occasion of the Joint Statistical Meetings), Brad inspired me to start running more often. He is therefore also responsible for my becoming a marathoner."

Chris Gotwalt (@chris_gotwalt1):  Brad Jones’s contributions to the design and analysis of experiments are huge. His invention of the Profiler is ‘interpretable AI’ at its very best, even though it preceded that term by three decades. His other great contribution is championing optimal design of experiments until it became widespread and mainstream. This is the idea that the design of and experiment should reflect both the goal of the experiment, as well as directly incorporating the various resource constraints like sample size, randomization restrictions, and combinations of factor settings that are physically possible. While this may seem like a very natural and obvious idea now, there was a long time when this notion languished and was actually even considered a risky, bad idea. So, in addition to overcoming the various computational and UI challenges, Brad worked strategically to win over both practitioners in the industry as well as other thought leaders to make optimal design accessible and an acceptable approach to problem solving in the industry. Every day we all use many products that have been made better with these tools that Bradley Jones developed and championed.

Caleb King (@calking): "Before coming to JMP, I had heard about Brad and met him a few times at conferences. But it wasn’t until I started at JMP that I realized just how amazing he was! And I’m not just talking about his accomplishments. Brad has been the best mentor one could ask for. He has always advocated for me and given me valuable advice and guidance on my career. I’ll be sad to see him go, but I know his retirement is well-earned. Though I wouldn’t be surprised if he was just as productive in retirement as he was in the workforce."

Ryan Lekivetz (@Ryan_Lekivetz): "Even prior to joining company JMP, I was truly impressed by Brad's prominence within both the academic community and among practitioners. This prominence is one of the main reasons I applied to JMP. However, it was only after becoming a part of his team that I realized the profound impact his message had on the way in which experiments are performed. His emphasis on generating experimental designs that align with the specific requirements of each experiment, rather than forcing experiments into pre-existing designs, has been nothing short of transformative. I take great pride in being a member of the team he has assembled, and I am determined to carry forward the spirit of innovation and curiosity that he has instilled. I eagerly await news of Brad's next ventures, and I sincerely hope for the opportunity to collaborate with him on future projects."

Douglas Montgomery: "I’ve been a friend and colleague of Brad Jones since the late 1980s. Everyone in the design of experiments community should acknowledge his enormous contributions to our field. These include response optimization (the Prediction Profiler in JMP), construction and analysis methods for non-regular fractional factorial designs, optimal designs, split-plot designs, optimal designs for multi-response experiments, and definitive screening designs.  It has been my privilege to work with him in some of these areas, including co-authoring a textbook on a modern approach to teaching experimental design that is structured around an optimal design approach. He has also been generous with his time in working with several of my Ph.D. students on their research.  We have all benefited from his knowledge and experience in the field."

Joseph Morgan (@Joseph_morgan2): In 2006, a year after I joined the JMP team, several of us were walking back to our offices in Building S from the Building T cafeteria after lunch. Brad and I were walking together and I brought up the topic of factor-covering designs, a name that Colin Mallows, the statistician, had proposed for covering arrays in a Technometrics paper. Brad was unaware of these designs but he was intrigued and so, to my surprise, we wound up spending several days investigating whether the coordinate exchange algorithm would be a reasonable general-purpose algorithm to construct such designs. We eventually concluded that coordinate exchange was not a promising approach. A few years later, having moved to SAS R&D from JMP, I got an email from Brad asking if I would be interested in implementing a JMP Pro DOE platform to construct covering arrays. I accepted without hesitation. To me, this arc of events captures who Brad is. Intellectually curious about all things DOE, willing to investigate radically different constructs and ideas that pertain to DOE, and singularly focused on making JMP DOE best in class. This is the environment that I now work in, with colleagues, Caleb, Ryan, and Peng, who all share this singular vision. Thanks, Brad.

Chris Nachtsheim: Brad Jones and I had a meeting of the minds 40 years ago in New Mexico (at the Rancho de Chimayo) when the Statistical Sciences group at Los Alamos attempted to hire him, and we’ve worked closely together ever since.  Brad’s impact on the world of DOE and data science has been immense, if not unsurpassed! A few highlights: 

· The invention of the prediction profiler, an amazing, interactive tool for studying the nature of response surfaces and interactions.
· Bayesian D-optimal designs. The widely-cited paper by Brad and Bill DuMouchel made the use of Bayesian D-optimality practical and accessible to experimenters while providing an easy way to make optimal designs robust to model misspecification. Among other things, this paper led to Brad’s later development of Bayesian supersaturated designs.
· The invention of the custom design facility in JMP. This brought the world of optimal design to practitioners in an easily understood way for the first time.
· The invention and development of Definitive Screening Designs (full disclosure: with me). DSDs have been adopted worldwide with enthusiasm by practitioners and are rapidly supplanting fractional factorial designs and the primary tool for exploratory
experiments.
· The invention of fast, flexible filling designs for computer experiments and their widespread adoption by the data science community.
· His innovative books on case studies in optimal design with Peter Goos and on modern experimental design with Doug Montgomery.

In sum, I would cite Brad’s evangelical advocacy for the implementation of the scientific method through the design of experiments.

Yeng Saanchi (@mysaan): Bradley Jones is a mentor and friend. Underneath the aloof exterior is a kindness and thoughtfulness that I’ve had the pleasure of experiencing firsthand. His extensive knowledge of DOE, as well as the impact he has made and continues to make on the field, are greatly inspiring. Brad, I would like to thank you sincerely for all your help, especially for taking the time to answer my questions during my time as a student. Your support and insights were truly invaluable. It’s hard to believe that I will no longer be able to run up to your office to ask a question or simply say hello, nor will I hear your unmistakable knock at my door to call me to lunch. As hard as it is for me, it must be even harder for you to leave the place where you have experienced so much growth, both personal and professional, for more than two decades. To borrow the words of J.R.R. Tolkien, “I will not say: do not weep; for not all tears are an evil”. I bid you a very fond farewell.

It has become a vital tool in product research, serving as the key to modernizing the trial-and-error process to make better products, better manufacturing techniques, and better processes.

Research career

In the 1980s, DOE was considered a sleepy discipline, one in which all the most valuable breakthroughs had already happened, with the expectation that any additional improvements would be incremental. That attitude was soon proven wrong, with many huge breakthroughs occurring over the next 30 years. The statistician that drove the most valuable research in DOE over that time has been our own Bradley Jones, with input from his many collaborators.

Brad had been working in experimental design for many years, beginning with BBN software, the leading industrial statistics software vendor in the 1980s. Then he co-founded a new company, Catalyst, which created innovative experimental design software, including the profiler. He then moved to MathWorks, a leading engineering math software product, where he authored the Statistics Toolbox.

In 1997 he came to JMP, where he saw its potential to become the leader in industrial statistical software. JMP had just begun improving its offerings for engineers, and DOE was one of the three key specialties to unlock that market, along with quality and reliability.

Brad’s initial contribution was the platform Custom Design. Computers are powerful, so why not harness that power to produce experimental designs that are custom optimized for a given situation – the field of optimal design? Previously, optimal design had been reserved for specialized problems handled by specialists, not for mainstream challenges, but Brad saw that every engineer could benefit from optimal design. Optimal design could also make the process easier and more direct. Before Custom Design, engineers would look over textbook design generators where you had to understand concepts like resolution number and confounding patterns, and you would be limited to designs that were sized to a power of two or selected from a catalog. After custom design, all you had to do would be to describe the factors, which effects you wanted to be able to estimate, and how many runs you could afford.

To make optimal designs practical, an optimization algorithm was needed. Most optimal design software at the time, such as PROC OPTEX from SAS, required the user to generate large numbers of candidate runs, from which the algorithm determined the best subset of runs to optimize the criterion. But that made the construction burdensome. The breakthrough, from Chris Nachtsheim and Ruth Meyer in 1995, was the coordinate exchange algorithm, which did not require candidate sets, and was, therefore, more direct, simple, and efficient. Brad harnessed it to produce the Custom Design platform, first in JMP 4.

That was the first in a long series of innovations.

An early innovation was the concept of tagging effects in the model with an “Estimability” attribute of either “Necessary” or “If Possible.” With a limited number of runs, it is rarely possible to be able to estimate all the desired effects – especially higher-order interactions. With the “If Possible” setting, the algorithm first makes the “Necessary” effects estimable, and then tries to make as many “If Possible” effects estimable as possible. This option was an implementation of Bayesian Optimal Design, which Brad invented with BBN collaborator Bill DuMouchel and published in Technometrics in 1994, the first of many DOE articles Brad co-authored in refereed journals.

But in a given experiment, it usually happens that some factors are much stronger than others, and the goal of a screening experiment is to find which factors are important. So why not use a supersaturated design, and then use a specialized method, like stepwise regression, to find the important factors? To make a supersaturated design, Brad realized that a good way was to use the Bayesian D-Optimal method, and just declare all your factors “If Possible.” This led to other papers, one of them with Dennis Lin, who was also a pioneer in supersaturated designs. It is a powerful advance to be able to screen many factors with only a few runs.

Another early challenge was handling split-plot designs. Many experiments have a kind of restriction where groups of runs must be at the same level of some factor. A classic example is heating runs in an oven, where all the runs need to be treated at the same temperature. The characteristic feature here is that some factors are hard to change, while others are easy to change. The goal is to create an experimental design where the hard-to-change factors are constant within a blocking group. Peter Goos, a statistician at the University of Antwerp, made some breakthroughs on optimal design for split plots and published his findings. Brad put those ideas to work with coordinate exchange to obtain a practical implementation in custom design. When Peter and Brad met at a Fall Technical Conference, Brad showed him how coordinate exchange could make split-plot designs practical, thus beginning a long collaboration between the two.

at the University of Antwerp, leading to many months of intermittent travel to Antwerp to further develop his ideas on DOE. For his dissertation, Brad put together four big ideas, which all but one were accepted for publication in refereed journals before Brad’s final oral exam. The last was later accepted by Biometrika, a top journal. Peter organized a DOE conference in Antwerp and invited many DOE experts from Europe and the U.S. The conference was much like a series of tribute sessions for the contributions from Brad and his collaborators. The highlight of the conference was Brad’s oral examination under scrutiny from his robed Ph.D. committee members, concluding with a successful verdict and a tribute speech by Peter.

Then Brad got even busier with research.

For example, what if a design is fine at estimating main effects in a model, but there is a strong second-order interaction that is not in the model? In that case, it might be that the interaction is biasing the estimates of main effects. But it is often possible to construct the design in such a way that the main effects are orthogonal to the second-order interactions, and consequently there is no way for a strong second-order interaction to bias the main effect estimates. That situation began a line of research into “minimal-aliasing” designs that modified the optimization algorithm to make the main effects as uncorrelated as possible from interactions, while still maintaining their estimability and power. Brad collaborated on this work with Chris Nachtsheim from the University of Minnesota.

While playing with minimal-aliasing designs involving three-level factors, Brad noticed that some of the resulting designs had a curious fold-over structure. Fold-over runs are sign-reversed from other runs. The discovery led Brad and Chris to develop definitive screening designs (DSDs). The discovery of DSDs was very important for a variety of reasons:

• They were three-level designs, which allowed any curvature in the effects to be modeled.
• The main effects were orthogonal to the interactions, meaning any unmodeled interactions wouldn’t bias the main effect estimates.
• They were easy to construct without going through an optimization.
• They had very good projection properties so that if some factors were inactive, lots of interactions with the active effects were estimable.
• They allowed strong interactions to be found that would not be discoverable with other designs.
• And they were small, requiring a run budget no greater than the traditional fractional factorial designs that had none of these desirable attributes.

Dennis Lin later characterized these in terms of fold-overs of a conference matrix. DSDs became very popular in a short amount of time.

The next chapter in Brad’s career brought him back to supersaturated designs, where the number of factors is greater than the number of runs, and you hope that effect sparsity will allow you to find the big effects. Brad noticed that if you did a Kronecker matrix product of the Hadamard matrix with a subset of rows of another Hadamard matrix, you get a supersaturated design with desirable properties. These are the group-orthogonal supersaturated designs (GO-SSDs). Factors are assigned to groups, and the groups of effects are uncorrelated, but there are dependencies within each group. You can detect when groups are active and have a pretty good chance of detecting which factor within a group is significant. But the amazing thing about GO-SSDs is that you can get an independent estimate of the error by devoting some factors to be unassigned (fake factors) concentrated in one group, and the error for this group estimates the error variance. This work was done in collaboration with JMP Advanced Analytics R&D Manager Ryan Lekivetz, Chris Nachtsheim, and two others.

Currently, he is collaborating with others on mixed level designs, using some of the Kronecker-product experiences from earlier work. Under optimal design, Brad pursued several optimality criteria: I-Optimal design for better prediction with continuous response surfaces, and A-Optimal designs that allow weighting and have other desirable properties. Brad worked with Peter to coauthor a book, “Optional Design of Experiments: A Case Study Approach.” Brad coauthored several papers with popular statistics textbook author Doug Montgomery on various topics, as well as co-authoring “Modern Experimental Design Methods and How to Use Them.” He worked with Advanced Analytics R&D Senior Director Chris Gotwalt on optimal spherical designs and optimal nonlinear designs, and with Ryan on optimal space-filling designs.

A common theme of Brad’s research is that it was all in collaboration with other researchers, sharing and expanding the scope of the ideas. Having collaborators also helped greatly the completeness of vision and polish of the journal articles, which won many awards.

Brad was extremely well-regarded by veteran DOE researchers. Brad had a close working relationship with Stu Hunter and co-authored a paper with him when Stu was in his 90s. Brad cohosted a celebration in honor of Stu Hunter’s 100^th birthday at the USCOTS conference. George Box also highly regarded Brad, honoring him by giving him a DOE cube that George had used many times in his teaching. Brad wrote a tribute article to George Box, which became the most-read blog we have ever hosted.

Software career

The important part for Brad was not just doing the research but putting the best technology in DOE into the hands of practitioners: the scientists and engineers who would use our software to design their experiments. First unveiled in JMP 4 around 2000, each release of JMP would implement further features and other improvements in DOE. Later, Brad started assembling a team to further advance our software. Ryan Lekivetz was hired away from the University of British Columbia. Principal Research Statistician Developer Joseph Morgan was hired away from SAS to work on covering arrays. Senior Research Statistician Developer Caleb King was hired from Sandia National Labs to work on reliability and other DOE aspects. Together, this team has accumulated more patents in a short time than any other team at SAS. The most recent release has brought out Easy DOE, wrapping the whole experimental process into one easy-to-use package.

Our DOE facilities are rich in diagnostic devices, such as the Fraction of the Design Space Plot, color maps on correlations, prediction variance profilers, power analysis, and various efficiency measures.

Brad was also instrumental in helping recruit other leaders to JMP, including former head of JMP Sales and Marketing John Leary and Sales Vice President Dave Richardson.

With the team that Brad has built, we will continue our leadership in the DOE field.

Professional organization work

Brad has often volunteered to do peer-review work for statistical journals. He served as Editor-in-Chief for the Journal of Quality Technology (JQT) and as an Associate Editor for Technometrics, JQT, and Quality Engineering.

Brad has been invited to speak at professional meetings, such as the Joint Statistical Meetings and the Fall Technical Conference, as well as at many JMP conferences. He has spoken at many university and corporate campuses.

In his spare time

• Brad’s bachelor’s degree was not in statistics, it was in Music, at the University of Cincinnati. He majored in violin and did some professional gigs as a violinist, along with volunteer gigs and a few JMP events, and still practices regularly.
• Brad is a long-time Go player and has a fairly high amateur rating.
• For many years Brad was a professional dog breeder, specializing in Rhodesian Ridgebacks, that were highly rated. Brad often competed in dog shows.
• Brad has also competed in several marathons.

Brad plans to continue his research while in retirement, and we expect that he will visit JMP often and continue to collaborate with us. He leaves Ryan Lekivetz to continue in his role as the manager of the DOE and Reliability group.

Brad has brought tremendous value to our users – and to the whole profession of experimental design. DOE is a key technology for industry, and Brad, with his collaborators, has led the advances of the state of the art for a generation. Thank you, Brad, for all you have done and for being a great friend to us.

Feature StoryRe: Brad Jones' phenomenal career in DOE

Thank you Brad for your incredible contributions and leadership you have graciously provided to JMP for 25 years!   Your pioneering spirit, research, and wisdom are a great inspiration to us all to build on your strong legacy.  

Re: Brad Jones' phenomenal career in DOE

My JMP life with Brad goes back to orientation day at SAS, December 1, 1997.  Brad was hired into JMP Development, and I was in JMP Marketing.  We were a small division back then, only around 30, so Sales, Marketing, and Development often met together in one room to discuss everything.  I recall a discussion where it was clear to Brad that I didn’t really get what DOE was all about.  He sat with me and explained enough for me to be a believer.  Thank you, Brad, for helping JMP grow for the last 25 years and thanks for assembling a team to keep it all going strong.  I hope you enjoy whatever you do next with the same passion you gave to JMP.  

Re: Brad Jones' phenomenal career in DOE

It has not only been an honor to work with Brad, but it has also been a pleasure. At my age, it is often interesting to look back and ask not 'What if?' but 'What if not?' Life is more interesting because of incidents where serendipity is in charge. Brad demonstrated what can happen when opportunity and vision come together, with a whole lot of effort behind them.

Re: Brad Jones' phenomenal career in DOE

I’ve spent much of my working life advocating for the use of DOE. This has become so much easier thanks to the innovations from Brad. While many potential users in our target industries come out of university with little appreciation for DOE, it doesn’t take long for them to see the potential. This is down to the inspirational work of Brad. The time it takes for our users to get pay-back from their use of JMP for DOE is little more than the time it takes to perform their first experimental runs and measure the response outcomes.  

Through DOE our users develop and deliver better, lower cost, and robust solutions in a timely manner. Enabling R&D project timelines to be reduced by 50% with the outcome of better optimised, robust solutions that are easier and less costly to operate. What an impact you’ve had Brad, and will continue to have. Extremely well done.

Thank-you and enjoy this next phase of your life. I’m 95% confident it will bring yet more innovations in DOE.

Re: Brad Jones' phenomenal career in DOE

Brad, thank you for all of your many contributions to JMP. You've accomplished a tremendous amount in your 25 years here. I wish you the best in retirement!

Re: Brad Jones' phenomenal career in DOE

Some of my favorite times at JMP were watching Brad speak at our marketing "Explorers" events (back in the day). He always garnered a huge crowd and helped build DOE champions across many customers! Thanks for all you did for JMP Brad!

Re: Brad Jones' phenomenal career in DOE

I remember first coming to know Brad in person at one of those "Explorers" events and learning a whole lot about DOE and DSD there, as a JMP User. I actually never met him one on one in person, but his demeanor and his brilliant work have always had an impression on me. One time at one of those big events, a customer asked: "Would you add replication to your design?" Brad smiled and paused for maybe 10 seconds, then humbly and concisely replied, "I would."  That answer (the way he gave it) really stuck with me. He probably could have gone in so many directions but he kept it simple. Still his community posts and recorded talks are incredibly useful -- those of you who've had even a small fraction of that 25 years working alongside Brad are incredibly lucky. 

Brad, best of luck in your new chapter!

Re: Brad Jones' phenomenal career in DOE

As I reflect on how much I have used experimental design in my career, I see Brad's hand in that throughout.  Many of my greatest successes in working in product R&D and a manufacturing were projects where DOE was applied and the Custom Design platform generated the design(s).  Some of those experiments were "million dollar" experiments in time and cost, but solved critical problems for products that ultimately generated billions in revenue over their lifecycle.  It was also a joy when I could teach someone else the principles of DOE and then, with some training and coaching, turn them loose with JMP to design and analyze their own experiments.  Thanks for your work and the impact it has had, and best wishes for your retirement! 

Re: Brad Jones' phenomenal career in DOE

In sports someone of Brad’s stature would have a farewell tour and fans could see them perform one last time. There would then be commentary about where they stood as the greatest of all time, or GOAT. Unlikely to see that but your work Brad will continue to inspire students, researchers, and practitioners for many years to come. Your work has opened countless doors and convinced many faculty to use JMP and to be passionate about it. Grateful to have worked with you Brad and congratulations on your accomplished career and upcoming retirement. Best wishes to the DOE GOAT from JMP!

Re: Brad Jones' phenomenal career in DOE

Indescribable gratitude to you.
Thank for you and your DOE !

Re: Brad Jones' phenomenal career in DOE

Brad,

Thank you for all the wonderful contributions you have made to JMP & DOE!!! Enjoy your retirement. This change of perspective will bring a lot of interesting things, I'm sure! And, if you'd like to improve your French during your retirement, I'd be delighted to have a chat with you.

Happy retirement!

Re: Brad Jones' phenomenal career in DOE

There were many reasons why I wanted to work at JMP. But the biggest reason was the chance to work with Brad. I couldn't have imagined then that I would get the chance to have Brad as an advisor for my MSc thesis. I can't understand how he has been able to work on so many important innovations in DOE and be such a great mentor to so many people. A truly amazing career. All the best for the future, Brad.

Re: Brad Jones' phenomenal career in DOE

To everyone - 

Thanks for sharing all the wonderful memories. I am deeply moved.

I wish the best for JMP and hope our paths cross again.

Best,

Brad

Re: Brad Jones' phenomenal career in DOE

The guru of Modern Design of Experiments (DOE), Bradley Jones, has gifted us a treasure trove of tools: Definitive Screening Designs, Group-Orthogonal Supersaturated Designs, Bayesian D-Optimal Designs, Minimal-Aliasing Designs, Split-Plot Designs, and the user-friendly Easy DOE in JMP. But the crown jewel is JMP's Custom Design. Thanks to him, we're not just crunching numbers; but creating solutions.

Re: Brad Jones' phenomenal career in DOE

As a fanboy, I'm in awe of Bradley Jones, the titan of Modern Design of Experiments. His collaborative innovations, including Definitive Screening Designs, Group-Orthogonal Supersaturated Designs, Bayesian D-Optimal Designs, Minimal-Aliasing Designs, Split-Plot Designs, and Easy DOE, have essentially defined "Modern DOE". JMP's Custom Design, his masterpiece, has changed the game, allowing us to shape the design to our problem. Thanks to him, we're not just crunching numbers; we're crafting solutions.

Re: Brad Jones' phenomenal career in DOE

Brad, I will always remember when I started with JMP and your patience with my many questions. Your impact to the business, our customers, and to the field is without measure - thank you for all of your work and many contributions. Congrats on your retirement!

Re: Brad Jones' phenomenal career in DOE

What an incredible and inspiring career journey! Congrats to you! Wish you happiness and best of luck in your new journey!

Re: Brad Jones' phenomenal career in DOE

DOE was the feature that got me introduced to JMP, and "Optimal Design of Experiments" was the first book I read about DOE.  I still very distinctly remember meeting Brad at a JMP workshop while I still lived in Texas and was relatively new to JMP.  If not for those touchpoints, I wouldn't have started using JMP at that critical moment at the start of my career.  I may never have gotten addicted to it after getting that jump in efficiency after one of my first DOEs, nor started introducing it to our own customers right afterwards.  I also wouldn't have gotten to the point where I could come and work here, introducing it to customers as a full-time job.  None of this would have happened if not for Brad.    

Re: Brad Jones' phenomenal career in DOE

Thank you Brad for all that you did to enhance JMP and the DOE area, to name a few.  Your accomplishments are outstanding and I know the work you did and shared will reach many generations to come.  Best to you in your retirement! 

Re: Brad Jones' phenomenal career in DOE

Brad, as I said in the interview with you, which will be available in August, the spillover benefits of your work are incalculable.  Thank you for your many, many contributions!  May you retire to many more good things.

Re: Brad Jones' phenomenal career in DOE

Brad, I cannot say thank you enough! I am a JMP user and now staff as a result of your efforts to make modern experiment designs and visualizing models easy. You may recall, in my previous company we were using Gosset which helped open the doors to optimal experiment designs but required grit and help from Bill Kappele to deploy Sloane and Hardin's code. Not so easy to get engineers and technicians excited about something that adds complexity to their lives! After getting our first licenses of JMP there was quite an acceleration in designed experiments in my team that quickly extended to other teams followed by other innovations in statistical problem solving -and more JMP licenses. These problem solving innovations led to profitable products and patents. I think of the customer designer and prediction profiler as very powerful gateway drugs:) Thanks also for the many years of mentorship!
