You Are a Reliability Leader, Now Make a Difference

You Are a Reliability Leader, Now Make a Difference

Your Reliability Engineering Leadership Role

Leadership is not a position or title within an organization. It is an attitude.

You’ve seen the internet meme’s about the difference between leadership and management. There is a difference and while not everyone is going to be in top management, everyone can (and should) be a leader.

As a reliability professional, you are conveniently looked to for leadership. You are expected to use your knowledge and skill to solve problems. To help teams solve problems. To improve the reliability performance of your system and across your industry. [Read more…]

The Perfect Strength and Stress Concepts

The Perfect Strength and Stress Concepts

Recently Peter Stuttard asked if I knew of a reference for the perfect strength and perfect stress concepts. I didn’t and asked for a bit of explanation of the phrases.

Here is his reply (via Linkedin, btw a great tool to get and stay in touch) posted with permission with minor formatting edits.

To learn more about Peter check out his Linkedin profile.

Fred

Thanks for responding so quickly, the concepts of Perfect Strength and Perfect Stress are related to your discussion re Parts Count and Parts Stress predictions and reading this on your web site prompted me to ask you about them. [Read more…]

Introduction to the Quality Triangle

Introduction to the Quality Triangle

Priorities and Balance

Have you ever worked on a project with no deadlines, unlimited resources, and boundless scope? Probably not.

Quality Triangle-1
The Quality Triangle

You may have worked under the guidelines of a quality triangle, also known as a project management triangle, iron triangle, or project triangle.

Why is that? Why the limits to our ability to create a product or improve a system?

First, the world we work and live within has limits. We have only so much time for work, only the available resources, and limited knowledge. We do our best with what we have to work with at the time.

Second, as I once was told while working on an accelerated test design, ‘if there isn’t a deadline, you’ll happily tinker with the plan and get the testing done.’ My boss was right of course.

The set of constraints shape our projects and products. By understanding the set of constraints, specifically how they frame decisions, then we can complete complex projects. [Read more…]

The Need to Improve the Reliability Narrative

The Need to Improve the Reliability Narrative

Little Compromises and Future Costs

In a recent Seth Godin blog, Counting beans he talks about the eventual costs of little compromises. The immediate benefit may be celebration worthy, yet

But overlooked are the unknown costs over time, the erosion in brand, the loss in quality, the subtraction from something that took years to add up.

This certainly applies to reliability as well. Deferring maintenance just one more month, addressing one more software bug can be done after shipping, and similar small shifts erode reliability of your system. [Read more…]

Using Reliability Goals to Set Requirements

Using Reliability Goals to Set Requirements

Customers of your product would like the particular one they have to work. To work over time.

If a product meets the customer’s expectation by working as long or longer than they expected it to do so, then they may consider your product reliable.

We use reliability goals to discuss the customer’s reliability expectations. It is the establishment of requirements that converts the customer expectations to development and production obligations. [Read more…]

Interviewing for Reliability Position with Senior Managers

Interviewing for Reliability Position with Senior Managers

Preparing for an Interview with Senior Managers for a Reliability Engineering Position

Organizations around the world are recognizing the value of reliability engineering. Or, they are realizing that creating a durable product that delights the customer is good for business.

Another contributor to the interest in reliable products is the news of recalls. One recall not only distrupts the normal course of business, it may alter the future of the company. It may cause the collapse of the organization. Some do better than others, yet a major, in the news, recall is something to avoid. Creating a reliable product helps.

So you made it past the initial round of interview and have been called back to talk to the senior folks. As with any job interview, being prepared helps you present your best self. Understanding the business drivers motivating an interest in reliablity is essential for your preperation. This is not how to prepare an accelerated test plan type question, rather it is about how the results of an ALT will provide relevant value to the organization. [Read more…]

Uncertainty and Risk Management

Uncertainty and Risk Management

We are rather good at being surprised when setting expectations for the future. This is the essence of risk. The difference between what we expect to occur or would like to occur, and what does occur.

The definition of risk in ISO 9000:2015 and ISO 31000 include the phrase “ effect of uncertainty”. Let’s remove some of the uncertainty around the term uncertainty in the context of risk and risk management. [Read more…]

The Connection of Reliability and Customer Expectations

The Connection of Reliability and Customer Expectations

Customers Experience Product Reliability in Real Time

In a customer’s mind, the product works or it doesn’t. If it doesn’t work as expected it has failed. This may or may not be a reliability problem.

A customer or someone using your product brings a set of expectations to the experience. The range of expectations may range from very little to very high functioning, value production, and durability.

Failures are defined by customers.

In part, this is the functional capability, the operating within specifications, and the durability. The customer’s definition of reliability may or may not follow the design specifications.

It is the comparison of what should happen to what does happen. [Read more…]

Use and Environmental profiles

Did you know that hot air doesn’t rise when there is no or very little gravity?

The electronics used to steer an oil exploration drill head 5 miles deep in the earth experiences 200°C sulfuric acid immersion along with continuous 50,000G shocks.

I used to think the environment under the hood a car was difficult. [Read more…]
