The Watch Keeper

Equipment Operators as Watch Keepers

The watch keeper of old guarded their people and possessions. They were found walking about looking, listening, and watching for changes that signaled danger. Their job was to look for hazards and quickly raise the alarm before all of them were invaded and killed or captured into slavery. With sufficient warning the home group could rally to the defence and counter-attack the enemy.

Times haven’t changed that much. Instead of being invaded by the enemy we now get consumed by plant and equipment problems. If only there was an effective way to spot problems coming our way and mount a counter-attack before being overrun. [Read more…]

How to Work with the Chief Risk Officer

Many CRO’s come from compliance, legal, or finance areas. They do not know operations or quality. This person is critical to quality‘s success with ISO 9001:2015 in terms of providing risk approvals, direction, and resources. The quality department should be flexible and work with the CRO, specifically: [Read more…]

Implementing the Right Preventative Action

There are two instances when you should implement preventative action. First, once a failure occurs and you would like to avoid similar future failures. Second, before a failure occurs, yet an undesired failure mechanism is likely to occur.

Like corrective action there is a wide range of possible preventative actions. The selection of the right actions requires considering customer expectations, business and legal factors, along with the technical and economic feasibility. [Read more…]

6 Tips to Enjoy Your Job!

I have told my own children for years now that I didn’t find the job that I loved until I was around 35. Truth is I was around 35 when I figured out what I enjoyed but I didn’t really enjoy doing it until around 4 years later when I had the courage to leave the large company I had worked at for 19 years and start a business of my own. Working on my own I developed a product, had to market and sell that product to build a brand name. I had to make sure that every customer engagement was a shining example of success and efficiency because I not only wanted more business, I wanted my customers to tell everyone they knew that when it came to RCM (Reliability Centered Maintenance) I was not only the best bargain, I was one of the best in the world.

The 7 Essential Elements of a Complete Request

Not every request we make is fulfilled. Not every assignment is accomplished. Not every task we assign is completed.

Why is that? Possibly, the lack of a complete request.

It may be the person we made the request to was incapable or decided to ignore us. Or, more likely, it may be our request was not clear.

An unclear request increases the chance the desired outcome will not occur. An unclear request permits misunderstanding and confusion to guide the path toward an unsatisfactory result.

Understanding the essential elements of making a complete request improves the chance the desired outcome will occur.

Let’s examine the 7 elements one at a time. [Read more…]

ANOVA Calculation Example

An Explanation and an ANOVA Calculation Example

Our white paper regarding t-test calculations has been very popular. Those that use the t-test tool regularly have commented “I finally understand what it is all about.”

The natural question they ask me next is “have you done anything with the F-test?” It is another common tool and one that is equally misunderstood.

Due to popular request, here is our attempt at explaining the F-test tool, in the two possible methods of use. [Read more…]

Understanding Functions – Part 2

Problems and Solutions

Do you consider yourself an FMEA beginner or are you more experienced? Challenge yourself with these problems about FMEA functions, and see how you do. One of the best ways to learn is by pondering application problems and seeing of you can solve them.

If you haven’t yet read last week’s article Understanding FMEA Functions – Part 1, it would be a good idea to read it now, as the questions are based on that article.

Get Your Parts Right: The Storeroom Manager

The Roles & Responsibilities of the Storeroom Manager

The storeroom manager has the responsibility of ensuring the right parts, in the right quantity, at the right time are available. But what if they are pre-occupied with other tasks to properly manage the storeroom? It increases costs, delays work and increases Mean Time to Repair. This series continues with the storeroom manager. With the storeroom manager clear on their roles and responsibilities, the storeroom can operate efficiently and accurately. [Read more…]

Is It Faster to Demonstrate Component Reliability at the System Level?

Here is a common situation that is considered when reliability testing is being planned. Let’s use letters to designate depth in a product component structure. The top level product is level “A” and a component in top sub assembly is “B”. A sub assembly, of a sub assembly, of a sub assembly, is at level “D”. So is it more efficient to test the component at level “E” or at level “B”?

Question: Is it more efficient to test the component at level “E” or at level “B” to demonstrate it’s individual goal? [Read more…]

What is Risk Based Thinking?

We get this question weekly and sometimes daily it seems.

Why? ISO has not defined Risk Based Thinking? And, this is a hugely important question because ISO has elevated RBT to the same level as PDCA and Process in the Final Draft International Standard (FDIS) of ISO 9001:2015.

One of the things we know is the marketplace hates a vacuum. Someone will develop a product or service to fill in the vacuum. This is exactly what we did with RBT. [Read more…]

Spherical Roller Bearings

Understanding the Basics of Spherical Roller Bearings

Spherical roller bearings (SRB) are popular because they can take very heavy loads and are self aligning. Their design allows them to take combined loads in both the radial and axial direction acting together. Each roller is loosely retained in place within a cage that goes full circle between the raceways. Figure 1 shows a simplified drawing of a spherical roller bearing on a shaft under deflection.

Labor Saving DFT: Built-In Self-Test

In honor of Labor Day, I thought I would jump over to the Built-In Self-Test (BIST) wing of the DFT Castle.

I will provide you with a quick tour. Then when you hear the term in a meeting you can follow along and ask a few questions.

BIST saves labor for the Automatic Test Equipment (ATE).

Though there’s no free lunch. BIST does require an engineer to labor—someone has to design it specific to the device under test (DUT). [Read more…]

Mandate and Commitment to Manage Risk

Risk Exists; Therefore, Manage Risk

Every organization, business, and individual faces a relentless barrage of risk. Some risks are minor, while others may overwhelm.

We all deal with risk, manage risk, in our own way. For more than just yourself the management of risk is taking on a new level of organization and importance.

Risk exists whether or not we choose to plan, prepare, and mitigate.

The decisions concerning product reliability, and associated risks, require senior management (including the board of directors) engagement and commitment. While there is a wide array of business and societal risks the management team must address, the reliability performance of products and systems presents potentially catastrophic risks to any organization.

What do you mean that my phone is obsolete?

Reliability engineers have traditionally been asked to answer a common question during development of a new device or system, and that is “How long will it last?”.

It is the eternal question in equipment reliability development, and it really comes down to “that depends on many factors”. One question that needs to be asked is how long do you need it to, or should it last? [Read more…]

DOE Supports World Class Quality

This is an example of a practical DOE that was used in the development of a manual window mechanism for a truck application. A similar process can be used for current mechanical and electrical design and development projects. In this article, you will see that the DOE method:
