She’s a Menace!

The Titanic had two sister ships, the Britannic and the Olympic. There was a woman called Violet Jessop, a nurse and a cruise liner stewardess that worked on all three. (That’s her, to the right->)

The Olympic crashed into a warship whilst leaving harbor but was able to make it back.
She was on the Titanic as it sank and is referenced in the Titanic film, a stewardess that was told to set an example to the non english speaking passengers as the ship sank. She looked after a baby on lifeboat 16 until being rescued by the Carpathia the next day.
It’s not known what exactly caused the sinking of the Britannic but the lifeboats hit the water too early. As the ship sank, the rear listed up and a number of the lifeboats were sucked into the propellers. Violet had to jump out of the lifeboat she was in and sustained a serious head injury, but survived.

Enabling People, Processes and Product Development

Clear roles and responsibilities for project managers and team leaders can significantly improve alignment of skillsets and overall teamwork

A generally accepted principle for a successful business is great people, processes & products. This can be further simplified as “maximizing customer value and minimizing cost” of the product.

Consider the following:

An excellent product development process should ensure maximum customer value while product cost is minimized
Process improvement minimizes (or reduces) costs across the enterprise
Project management ensures execution of product development, or process improvement products

Defeat Your Lizard Brain and Banish Procrastination Forever

Do you sometimes (or often) suffer guilt or frustration due to procrastination? If so, you are not alone. It’s a common perception that procrastination is an inherent personality flaw, the result of laziness or other slothfulness. People get frustrated by procrastinators and label them as lazy, untrustworthy, and unreliable.

However, in recent decades scientists have learned a lot about how our brains work that gives insight into procrastination and why it happens. It turns out that when your advanced human brain sets out to accomplish a task, but can’t see a clear path to completion, the doubting antiquated lizard brain takes over. Your lizard brain, a leftover instinct-driven antique from the days of the caveman, decides the apparently unsolvable is overwhelming, and creates a bad attitude toward the task. It’s fight or flight, and procrastination is the flight response to the stress created by the task. [Read more…]

ERM and Intelligent Risk

Guest Post by James J. Kline (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

In the Baldrige Excellence Framework the term “Intelligent Risk” appears. It is defined as: “Opportunities for which the potential gain outweighs the potential harm or loss to your organization’s future success.” This definition expresses a concern that risk might inhibit innovation. With the addition of Enterprise Risk Management to the 2017-18 Framework has a condition been created where two best business criteria, innovation and risk management, might cancel each other out? More basically, does Enterprise Risk Management (ERM) inhibit innovation related risk taking?

11 Motivations to Learn Reliability Engineering

There are many reasons or motivations to learn. From our boss asking us to solve a problem in an unfamiliar field of science, to simple curiosity.

When faced with an unusual failure mode, we need to learn what is causing the failure in order to solve the problem. When exploring a new material, we want to learn how it will fail in our design.

As reliability professionals, we are professional learners or should be.

Let’s take a look at a list of motivations that you may experience that prompt you to learn. When you review the past month or year, you will notice how much you learned.

When you feel one of these motivations, go with it. Learn, grow, and improve your capability as a reliability professional. Furthermore, you can foster these motivations with your team and colleagues, as well. [Read more…]

Finding Joy in the Workplace

This time of year, people talk a lot about joy and family. But what about finding joy in the workplace? Most people in the Reliability profession spend at least 40 hours each week at work (probably much more). That’s almost 25% of our total time, and more than 35% of waking hours if you average 8 hrs of sleep per night. Who wants to spend a third of their life without joy?

If your workplace is getting you down or just plain blah, here are some ways to make a change. [Read more…]

Quality and Innovation

Guest Post by James J. Kline (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

Introduction

In 2015, innovation was added to the Baldrige Excellence Framework. While there is no doubt that innovation is important for an organization’s survival, a fundamental question is: How much does a quality improvement process, which is encouraged by the Baldrige Excellence Framework, contribute to innovation? While there is no simple answer to this question, some indication can be seen in an examination of the focus of the quality improvement process and what happens to a company, with a reputation for innovation, when a quality improvement process is implemented.

Such a company is Minnesota Mining and Manufacturing (3 M). And, a June 11, 2007 article in Business Week, entitled: “3M’s Innovation Crisis: How Six Sigma Almost Smothered Its Idea Culture”, argued that Six Sigma inhibited 3M’s ability to innovate. This piece discusses the 3M experience and the relationship between Six Sigma and Innovation.
