I started my data analysis career in the Space Shuttle Program,
as part of the Trend Analysis and Corrective Action Department at
Kennedy Space Center.
My group searched for trends and recurring problems in the vast

you ever tried to install ventilated shelving in a closet?
You know: the heavy-duty, white- or gray-colored vinyl-coated wire
shelving? The one that allows you to get organized, more efficient
with space, and is strong and maintenance-free? Yep, that’s the
one. Did I mention this stuff is strong? As in,
really hard to cut?
It seems like a simple 4-step project. Measure the closet, go

In Part 1 of this blog series, I
compared Six Sigma to a diamond because both are valuable, have
many facets and have withstood the test of time. I also explained
how the term “Six Sigma” can be used to summarize a variety of
concepts, including philosophy, tools, methodology, or metrics. In
this post, I’ll explain short/long-term variation and

you know the most popular diamond cut is probably the Round

modern Round Brilliant Diamond Cut was introduced by an Italian
named Vincent Peruzzi, sometime in the late 17th century. In
the early 1900s, the angles for an "ideal" diamond cut were
designed by Marcel Tolkowsky. Minor changes have been made
since then, but the angles... Continue Reading

For all you creative and fun-loving folks out there, in this
blog post I'm going to share a puzzle instead of a story or lesson.
The holiday season is getting into full swing here in the United
States, and that gives us an opportunity to pause and reflect, and
even have a little fun while still thinking about how we can
improve our processes and products.

inference uses data from a sample of individuals to reach
conclusions about the whole population. That’s a very powerful
tool, but you must check your assumptions when you make statistical

Statistical inference uses data from a sample of individuals to
reach conclusions about the whole population. It’s a very
powerful tool. But as the saying goes, “With great

false negatives, thus invalidating... Continue Reading
