‘Statistics’ is a rising star. Everywhere I
turn, people are talking about data and the value of being able to
analyze and act on it. As someone who’s been writing about that for
years, I say it’s about time.
Statistics is like a talented
actress whose decades of appearing off Broadway have finally paid
For years, her work has been enriching our lives without us
knowing it. Statistics helps... Continue Reading
to this article published on Food Tank,
over 22 million pounds of food is wasted on college campuses each
year. Now that’s a lot of food waste!
Students all over the country are noticing excessive food waste
at their schools and are starting programs to bring awareness and
improve the problem. Naturally, many of these programs have roots
in Lean Six Sigma. In one example, a group of... Continue Reading

A problem must be understood before it can be properly
addressed. A thorough understanding of the problem is critical when
root cause analysis (RCA) and an RCA is necessary if an
organization wants to implement corrective actions that truly
address the root cause of the problem. An RCA may also be necessary
for process improvement projects; it is... Continue Reading
week is National Healthcare Quality Week, started by the National
Association for Healthcare Quality to increase awareness of
healthcare quality programs and to highlight the work of healthcare
quality professionals and their influence on improved patient care
In honor of the celebration, I wanted to point you to a few case
studies featuring Minitab customers in the healthcare field... Continue Reading
In 2007, the Crayola crayon company encountered a problem.
Labels were coming off of their crayons. Up to that point, Crayola
had done little to implement data-driven methodology into the
process of manufacturing their crayons. But that was about to
change. An elementary data analysis showed that the adhesive didn’t
consistently set properly when the labels were dry. Misting crayons
as they went... Continue Reading
Before I joined Minitab, I worked for many years in Penn State's
College of Agricultural Sciences as a writer and editor. I
frequently wrote about food science and particularly food safety,
as I regularly needed to report on the research being conducted by
Penn State's food safety experts, and also edited course materials
and bulletins for professionals and consumers about ensuring they
had safe... Continue Reading
previous posts, I discussed the results of a recycling project done
by Six Sigma students at Rose-Hulman Institute of Technology last
spring. (If you’re playing catch up, you can read Part I and Part II.)
The students did an awesome job reducing the amount of recycling
that was thrown into the normal trash cans across all of the
institution’s academic buildings. At the end of the spring... Continue Reading
This week I'm at the American Society for Quality's World
Conference on Quality and Improvement in Nashville, TN. The ASQ
conference is a great opportunity to see how quality professionals
are tackling problems in every industry, from beverage distribution
to banking services.
Given my statistical bent, I like to see how companies apply
tools like ANOVA, regression, and especially... Continue Reading

Predicting project completion times is one of the major
challenges project managers face. Project schedule overruns are
quite common due to the high uncertainty in estimating the amount
of time activities require, a lack of historical data
completion, organizational culture, inadequate skills, the complex
and elaborative nature of... Continue Reading
Suppose that you have designed a brand new product with many
improved features that well help create a much better customer
experience. Now you must ensure that it is manufactured
according to the best quality and reliability standards, so that it
gets the excellent long-term reputation it deserves from potential
customers. You need to move quickly and seamlessly from Research
and Development into... Continue Reading

An alarming number of borewell accidents, especially involving
little children, have occurred across India in the recent past.
This is the second of a series of articles on Borewell accidents in
India. In the first installment of the series, I used the
G-chart in Minitab Statistical Software to predict the
probabilities of innocent children... Continue Reading
In part 1 of this post, I covered how Six Sigma students at
Rose-Hulman Institute of Technology cleaned up and
prepared project data for a regression analysis. Now we're
ready to start our analysis. We’ll detail the steps in that process
and what we can learn from our results.
What Factors Are Important?
We collected data about 11 factors we believe could be
Whether the date of... Continue Reading

Previous posts on the Minitab Blog have discussed the work of
the Six Sigma students at Rose-Hulman Institute of Technology
to reduce the quantities of recyclables that wind up in the trash.
Led by Dr. Diane Evans, these students continue to make an
important impact on their community.
with any Six Sigma process, the results of the work need to be
evaluated. A... Continue Reading
I left off last with a
post outlining how the Six Sigma students at
Rose-Hulman were working on a project to reduce the amount of
recycling thrown in the normal trash cans in all of the academic
buildings at the institution.
Using the DMAIC methodology for completing improvement
projects, they had already defined the problem at hand: how could
the amount of recycling that’s thrown in the normal trash... Continue Reading
I typically attend a few Lean Six Sigma conferences each year,
and at each there is at least one session about compensating belts.
Any number of ideas exist out there, but they commonly include
systems that provide a percentage of savings as a portion of pay or
provide a bonus for meeting target project savings. There are
always issues with these pay schemes, including the fact that... Continue Reading

Here's a shocking finding from the most recent ASQ
Global State of Quality report: The higher you rise in
your organization's leadership, the less often you receive reports
about quality metrics. Only 2% of senior executives get daily
quality reports, compared to 33% of front-line staff members.
A quarter of the senior executives reported getting quality
metrics on a monthly basis, at least. But... Continue Reading

India, we've seen this story far too many times in recent
Timmanna Hatti, a six-year old boy, was trapped in a 160-feet
borewell for more than 5 days in Sulikeri village of Bagalkot
district in Karnataka after falling into the well. Perhaps the most
heartbreaking aspect of the situation was the decision of the
Bagalkot district... Continue Reading
Learning to ride a bike is a rite of passage for any kid, so
much so that we even use the expression "taking the training wheels
off" for all kinds of situations. We say it to mean that we are
going to let someone perform an activity on their own after
removing some safeguard, even though we know they will likely
experience failures before becoming proficient at it.
You see, riding a bike requires... Continue Reading
Christi Health, the largest provider of healthcare in Kansas,
operates a Center for Clinical Excellence that's made up of a team

I learned not only about the areas of patient care where they
are targeting improvements, but about... Continue Reading
