Sturge’s Rule: A Method for Selecting the Number of Bins in a Histogram
If you’ve worked around the fields of reliability or quality for any length of time, you’ve certainly encountered and have likely assembled the humble yet mighty histogram. This specialized bar graph is one of the most common starting points for analyzing continuous data. It not only portrays the frequency of numerical data across its range of values, but also provides hints at the data’s underlying probability distribution. [Read more…]

Using FMEA quality objectives to audit FMEAs
In last month’s article we discussed the most common FMEA mistakes and how to convert them into quality objectives. This month we will focus on how to audit FMEAs, using the FMEA quality objectives as a guideline.
“Twice and thrice over, as they say, good is it to repeat and review what is good.” Plato
Thomas Jefferson’s Role in Modern Manufacturing: Interchangeable Parts
My limited formal training about America’s Industrial Revolution came in tenth grade history class. And my few remaining recollections of my studies from that era include characters like James Watt and Alfred Nobel, and their inventions, the steam engine and dynamite. Oh, and how could I forget Eli Whitney and his cotton gin?
Now 40 years later, my interest in manufacturing has grown far beyond these elementary school lessons, and the Industrial Revolution continues to intrigue me. Yes, this era was rife with its inventors and their inventions. But the enduring gains from this era were the philosophies of manufacturing that transcended the specific inventions. [Read more…]

Root Cause Analysis — What is 8D?
The “D” is 8D stands for “disciplines”, and the 8D process is a problem-solving methodology employing eight sequential disciplines or steps that can be applied to a wide range of industries, situations, and disciplines.
The 8D process was developed in the late 1980’s by the Ford Motor Company to give its engineers a standardized method for dealing with design and manufacturing problems. Ford’s predecessor to 8D was called “TOPS”, Team Oriented Problem Solving. This is a fitting name to the methodology since it strongly emphasizes a team-based approach. In fact, the first of the eight D’s is “Assemble the Team”. [Read more…]
