Asset Healthcare Management

Guest Post By: Luis Daniel Khalil

Condition monitoring can help to predict failures and anticipate to them, however it doesn’t always work like this — in the best case scenario we might be able to identify early phase failures or incipient stage of damage mechanisms or failure mechanisms, but if we use it in the wrong manner it will just be a reactive tool.

More than 80% of the failure modes could be randomly patterned. Although performance, vibration, temperature or lube oil condition are being monitored, many of the failures are still not directly predicted by only these conditions. [Read more…]

Case Study: Creating a Spare Parts Purchase List with Confidence

Guest Author: Jason Ballentine, VP of Engineering for ARMS Reliability

Starting from Scratch with Spares

As anyone with a hand in running a household knows, it’s important to keep a stockpile of key items. You certainly don’t want to find out the hard way that you’re on your last square of toilet paper. But in the case of a facility like a power plant, a missing spare part could be more than just a nuisance—it could be downright expensive. [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…]

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…]

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.

Reliability and Risk Mitigation Actions

Once reliability risks have been identified and analyzed, we have to do something.

Well, not really.

If the risk is acceptable to the stakeholders, then we can simply continue with the current plan and monitor or any new risks or changes in our understanding of the existing risks.

Risk mitigation is a ‘system, process, or investment to control the likelihood or consequence of a risk.’ This is according to the glossary of risk terms in ISO 31000: Enterprise Risk Management. In many cases, the risk is unacceptable and will require mitigation. [Read more…]

Determining Customer Reliability Requirements

Determining What Customers Really Want Concerning Reliability

Customers want the benefits created by your product. They want the time savings, the reduced yield loss, they want simplicity, coolness, speed, etc.

Customers buy your product to solve a problem, they do not buy it to simply enjoy the features. The features have to do something of value. They have to provide a benefit.

If your product fails, the feature doesn’t work. Customers do not realize the benefit they expected.

In short, your customer wants your product to work as expected. When asked a customer will tell you they do not want to have product failures. [Read more…]

The Quality Triangle and Reliability

How Does Reliability Fit with the Quality Triangle?

The Quality Triangle provides a method to establish priorities for a project. It strives to balance time, cost, and quality (or scope instead of quality). It does not include reliability.

Now I am a bit bias as a reliability engineer and believe a projects set of priorities should explicitly include reliability performance. Of course, there are many potential priorities, yet reliability certainly can make or break a product, it’s market acceptance, and an organization’s profitability.

So, given a quality triangle based set of priorities, how does reliability fit in? [Read more…]

A Framework for Risk Management

Making or supporting decisions involving product or system reliability is fraught with uncertainty. Is it reliable enough? Will failures occur prematurely? Are failures dangerous?

Uncertainty is risk.

In recent years more organizations and international standard bodies have focused on risk management. Identifying, analyzing, and mitigating uncertainty in a systematic manner.

There is not a set way for every organization to organize a risk management process. The ISO 31000 standard does describe a framework for the implementation of risk management within your organization. [Read more…]

CRE BoK and Risk Management

The New ASQ CRE BoK Group: Risk Management

The 2018 ASQ CRE Body of Knowledge has a new top-level section titled II. Risk Management.

A few of the topics, 6 of the 9, are the same or similar to topics in the previous CRE BoK. There are three new topics that extend the reliability engineers need to know, understand, and use risk management tools.

Overall the new section of Risk Management has three groups of topics:

A. Identification

B. Analysis

C. Mitigation

Let’s take a quick look at the details in this new section and highlight the changes and new elements. [Read more…]

Review of 2018 ASQ CRE Body of Knowledge

The new CRE body of knowledge goes into effect for exams starting January 2018.

The changes include topics that has been dropped, added, or altered. There also is a new structure with 5 main groups rather than the previous seven. Overall, the BoK remained pretty much the same with a reorganization of the topics.

Reading the new BoK and comparing it to the old BoK raises a few concerns or observations. Let’s take a look at the new structure and what the changes say about the reliability engineering profession. [Read more…]

Discussion skills

Discussion Skills for a Reliability Engineer

Talking is not the same as a discussion or conversation. Talking is one direction only. If two people are talking, they are talking at each other.

A discussion is two way. When two people have a discussion information passes both ways, both speak, both listen.

As an engineer, there is plenty to discuss. We work with others to find solutions, make compromises, determine optimizations, and finish projects. We need to share our knowledge and insights, as well as learn from others.

You can learn to foster true discussions and minimize simply talking at one another. You can take steps to enable the give and take exchange of a discussion. [Read more…]

8 New Topics in the ASQ CRE Body of Knowledge

Last week we reviewed the 10+ topics removed from the CRE body of knowledge (BoK). This week, let’s look at the additions.

Three of the additions are new categories or groups of topics that in part contain new topics. There are five new topics, that in most cases included bits and pieces of concepts buried in the previous BoK.

Let’s take a look at each additions in a bit more detail. Some I agree with, some I wonder what the motivation is behind the addition, and some I question why it is included. [Read more…]

10+ Dropped Items from the ASQ CRE Body of Knowledge

A Review of the 2018 ASQ CRE Body of Knowledge

I just noticed the new 2018 ASQ CRE Body of Knowledge had been posted on the ASQ site. The new BoK will be in effect for CRE exams as of January 2018. Thus, we have six months to adjust to the new body of knowledge.

This is part 1 of a multipart review of the new BoK. Here we’ll look at the parts that those preparing for the exam will not have to master or review. There are 10+ topics dropped completely or in part from the BoK.

In future articles, we’ll review what has been added, what has been changed (a review), and how to best prepare for exams based on the new BoK. Plus, we can look over past BoK’s to understand where reliability engineering practice is today.

In part, the logic is these sets of tools (topics) that are not widely used by working reliability engineers. In some cases, I agree, and in others, I don’t. Let’s look at the eight topics not found in the upcoming CRE BoK. [Read more…]

Listening Skills for Reliability Engineers

Listening Skills to Improve Your Ability to Communicate with Influence

Did you hear what they said? Or, were you busy loading for your next verbal barrage?

As my mother would remind me, one should listen twice of often as speaking. Something about the ratio of ears to mouths in the population. I have to agree with her, that one can learn a lot by listening.

Listening may not seem to be a skill that one needs to master. Yet, how often have you walked away from a meeting where one or more participants obviously were not listening? How often are points repeated in an effort to be heard?

Being able to listen, listen well, can be honed and improved. A focus on being a better listener will improve your ability to communicate and influence as a reliability engineer. It has benefits beyond our reliability work, too. [Read more…]
