2Abstract
- The statistics profession is at a critical
point in its history and has been for some time.
The May 2008 Technometrics article, Future of
Industrial Statistics, summarized many of the
major issues. Two key drivers are global
competition and the rapid growth of information
technology. The old model for the use of
statistical thinking and methods in business and
industry, which has been around for at least 50
years, does not work in todays business
environment. This presentation begins with a
brief summary of the current state of the
profession and then moves quickly to a focus on
what statistical organizations and statisticians
as individuals need to do to effectively deal
with the new environment. The focus is on
strategies and approaches that have been found to
work. Several case studies will be presented to
illustrate the new model and the needed changes.
3Agenda
- Todays Realities
- We Need to Change our Thinking
- What Should Statisticians be Doing?
- Helping Our Organizations Succeed
- Focus on Statistical Engineering
- Embedding Statistical Tools in Work Processes
- Summary
4Todays Realities
- Profession appears to be at a crucial point in
its history - Recent Technometrics article and blog highlight
major issues we must deal with going forward - Future of Industrial Statistics A Panel
Discussion - ASQ Stat Division Newsletter article by Vijay
Nair - Disconnect between academic research and practice
- We havent fundamentally modernized the model
for applied statistics since the 1950s - Pure science versus statistics as an engineering
discipline? - Leadership is lacking and desperately needed
- No evidence that we have critical mass to change
5How Should We Respond?
- Jump in fox holes and wait for the crisis to
blow over - Argue against globalization
- Understand the fundamental changes in our
environment, - Embrace them
- Adapt to them
- Take advantage of them
- Understanding todays environment will help us
understand the future of statisticians and
statistical organizations
The Choice is Yours Survival Isnt Mandatory

6Expanding World of StatisticsThe Profession Has
Responded
- Launching of Sputnik by the Soviet Union
- Created the need for design of experiments and
other statistical methods in research and
development - Food, Drug and Cosmetics Act created the need for
statisticians in the pharmaceutical industry - Clean Air Act and the Environmental Protection
Agency created the need for environmetrics and
the use of statistics in solving environmental
problems - Global Competition and Information Technology
creates need for improvement
Needs of Employers and Society Define the Roles
and Uses of Statistics
7Expanding Role of Statisticians
Consultant
Collaborator/Leader
- Consult on other peoples projects
- Perform routine analyses if needed
- Teach statistical tools
- Work with technical people
- Narrow expertise and accountability
- Benign neglect
- Lead or collaborate on our own projects
- Focus on significant, complex problems
- Design training systems
- Work with managers and technical people
- Broad expertise and accountability
- In the firing line
Computer Scientists Provide an Example of Such a
Role
8What Should Our Focus Be?
- Anyone can manage for the short term or the long
term real success comes from managing both short
term and long term at the same time - If you dont manage in the short term, there
wont be a long term (Jack Welch). - The complex problems of this world will not be
solved at the same level of thinking we were at
when we created them. (Albert Einstein) - We need to
- Think differently.
- Be bold but not reckless
9Helping your Organization Deal with the Global
Financial Crisis Short Term
- Cost reduction and short term cash flow
- Quick wins essential for sustaining change (John
Kotter) - Prudent risk taking
- Process understanding is needed
- Reducing variation reduces risk
- Effective prioritization working on the right
things - Improvement project selection
- Customer and employee surveys
- Follow the money
Statisticians Can Play a Major Role in Each of
These Areas
10Reinvigoration of Improvement Bottom Line
Improvement Never Goes Out of Style
- Some may respond, been there, done that.
- We have already done Lean Six Sigma, and now
moved on to bigger and better things - Improvement is particularly needed now
- Lean Six Sigma also helps us make sure that we
are working on the right things - The result will be
- Immediate, bottom line results
- Help with business prioritization
- Risk management approaches that balance need for
income generation with need to limit risk
11What Else Should Statisticians be Doing?A Longer
Term View
- Greater emphasis on statistical engineering
relative to statistical science - Embedding statistical methods and principles
into key business process - Making the use of statistical thinking and
methods part of how we work
12What Does Society Need from Statisticians?
- Decades of the 1950s, 60s and 70s
- Statistical science needed to be developed to
deal with the problems encountered in RD,
Manufacturing and other functions including - Efficient and effective experimentation
- Empirical modeling
- Process control
- Process optimization
- Need for statistical engineering was there, but
limitations of available methods created a
stronger need to develop statistical science. - 21st Century
- Society needs statistics to be primarily an
engineering discipline, with a secondary focus on
statistical science.
13Statistical Engineering
- Engineering focuses on how to best utilize known
scientific and mathematical principles for the
benefit of mankind. - Pure science works to advance our understanding
of natural laws and phenomena. - Example
- Chemist may attempt to advance understanding of
the fundamental science of chemistry - Create a new marketable substance
- Chemical engineer would more likely attempt to
better utilize the current understanding to
greater human advantage. - Determine how to scale up the process to produce
this substance commercially,
14Engineers Develop Engineering Theory
- Engineers do research to develop new theory
- Engineers theoretical developments
- Tend to be oriented towards the question of how
to best utilize known science to benefit society - Rather than on how to advance known science.
15Two Examples of Statistical Engineering
- Product Quality Management at DuPont
- Process and Organizational Improvement Using Lean
Six Sigma
16PQM Statistically Based Product Quality
Management System
- Product Quality Management (PQM)
- Framework for managing the quality of a product
or service. - Operational system the enables Marketing, RD,
Production and support personnel to work together
to meet increasingly stringent customer
requirements - Within two years product quality had improved to
the point of commanding a marketplace advantage
and more than 30 million had been gained in
operating cost improvements. The statistically
based Product Quality Management system developed
for Dacron was expanded to other products with
further contributions in earnings. - Richard E. Heckert
- Chairman and CEO, DuPont Company
- ASA Annual Meeting 1986
17PQM System Statistical Techniques Used
- Sampling Schemes
- Product Release Procedures
- CUSUM Process Control
- Shewhart Control
- ANOVA and Variance Components
- Inter-Laboratory Studies
- Design of Experiments
- Response Surface Methodology
- Graphical Tools

22Embedding Statistical Thinking in Core Business
Processes Some Examples
- Product Quality Management at DuPont
- Design and analysis of clinical trials conducted
by pharmaceutical and biotech organizations - Driven by FDA
- Track safety and injury data Mandated by OSHA
- Managers often study tabular reports and respond
to random variation - Plotting safety data over time on a control
chart, or even a run chart, can save a lot of
time and effort by providing a more insightful
view of the process performance. - If the appropriate statistical tools are part of
the information system, we would say that tools
have been embedded.
23Summary
- Whether we like it or not, our environment today
is radically different than even 10 - 15 years
ago - To prosper in the 21st century, statisticians
need to play broader leadership role - More pro-active and clearly value-adding.
- Focus should be on
- Bottom-line improvement It never goes out of
style - Significant, complex problems
- Statistical Engineering
- Embedding statistical approaches in work processes

25Cost Reduction and Short Term Cash Flow
- Bottom line improvement is needed today more than
ever before in, at least in recent history - Productivity System output / resources used.
- You can increase productivity by reducing
resources or by increasing system output. - We believe that the statistics profession could
be well positioned to identify ways to improve
the system - Reinvigoration of Lean Six Sigma can provide the
needed improvements - Big Opportunity Project selection
26Prudent Risk Taking Process Understanding is
Needed
- Prudent risk taking can be done when we
understand our processes - Critical process drivers
- Capability of the processes to meet customer
requirements. - Greater use of data and statistical tools can
lead to better process understanding. - Statisticians have much to offer regarding
quantifying risk and making decisions in the face
of this uncertainty
27Effective Prioritization Working on the Right
Things
- Effective prioritization is always important, but
particularly critical in this economy. - Many companies have gone through massive layoffs.
- There are simply fewer resources available, both
in terms of people and money. - Yet work has to be done if results are to
improve. - Careful prioritization of critical needs is
required to identify what must be done and what
can be dropped or done later - Statisticians can help the organization
- Focus on a few key strategies,
- Use data to identify and prioritize improvement
opportunities - Use employee and customer surveys to identify
opportunities, - Follow the money - large income and expenditures
are often opportunities for improvement.
