Is Your Greatest Reliability Asset Underutilized?

Is Your Greatest Reliability Asset Underutilized?

In today’s short video, I share how the delivery of our new metal building reminded me of a key aspect of Reliability Centered Maintenance (RCM). RCM was designed to be carried out with a Facilitated Working Group approach, bringing together a team of equipment experts to answer the RCM questions.

By using this approach, not only do you get comprehensive answers, but you also capture and memorialize the knowledge and experience of your experts—something that could amount to over 100 cumulative years’ experience in the room!

Even if one of your team members retires or moves on, their knowledge remains. Watch to find out how you can make the most of this valuable resource.

B10 Life for Weibull and Lognormal Distributions

B10 Life for Weibull and Lognormal Distributions

Dear friends, we are happy to upload this video on how to estimate B10 life when failure data follows Weibull or Lognormal Distribution. Your feedback on the video is welcome!

This video from the Institute of Quality and Reliability explains how to determine BX life for products that follow Weibull and log-normal distributions. BX life is defined as the time by which X percent of items are expected to fail. For example, B10 life means that 10% of items are expected to fail, which implies a 90% reliability.

We recommend watching following videos before watching this video for better learning experience:

Weibull Distribution Part-1

B10 Life for Exponential Distribution

Normal Distribution and Z-Score

3: Concept & Feasibility Phase – Part 2: Feasibility

by Mike Freier

The feasibility phase addresses two questions. First, can your design be made into a manufacturable product? And, second, how will you sell your product and to whom?

Validating the feasibility of manufacturing a new product is the next chapter in our series by Mike Freier on how to take a new hardware product from idea to scale.

Continuous Improvement

Continuous Improvement

Continuous Improvement in product development is a systematic and ongoing approach to enhancing products processes and services. This concept is crucial for organizations to stay competitive, meet evolving customer needs, and maintain product quality.

Let’s explore the key concepts of continuous Improvement in product development. Continuous Improvement is an iterative process tha 2involves constantly evaluating and refining products and processes. It’s not a one-time effort but a cyclical approach that allows for ongoing enhancements based on feedback.

Should One Profit From Failures?

Should One Profit From Failures?

“Do not improve reliability as it cuts into our repair activity profits.” Is this a way to run a reliability program?

I’ve seen this in action and that company is no longer in business. In another situation the field service department withheld vital information to improve products lest his department (and self-importance) dwindle.

Is this a bad business model, or is it just my thinking it not so smart? [Read more…]

When Should a Company Self-Disrupt

When Should a Company Self-Disrupt

By Greg Hutchins (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

So, when should a company self-disrupt? Or, more importantly when should you self-disrupt.

Companies face these disruptor questions:

  1. What are possible triggers to start (your) self-disruption?
    1. When should they (you) self-disrupt?
      1. How quickly should they (you) self-disrupt?
        1. How should they (you) self-disrupt?
          1. What’s their (your) final destination?
            1. How are they (you) going to monetize (make money)?
              All companies are searching for the next killer work model, app, platform, product, or idea. It’s too late when there are not enough products in the pipeline to create a sustainable competitive advantage. Companies learned this lesson the hard way.

The Role of Chance and Luck in Your Equipment Failures 

The Role of Chance and Luck in Your Equipment Failures 

Plant and equipment do not fail by accident. There are causes. Whether equipment fails depends on the capacity of their parts to handle stresses, when stresses are applied and the size of those stresses. These are probabilistic events – they are random, with many possibilities. Timing the start of failure, or its continuation to a breakdown, is mostly speculation because it depends on which past and future scenarios occur. It seems that luck and chance has a large say on the lifetime reliability of equipment. But there is a way to guide equipment reliability and performance toward the results you want.

Kaplan-Meier Reliability: What Could Possibly Go Wrong?

Kaplan-Meier Reliability: What Could Possibly Go Wrong?

SAS, JMP, R-”Survival”, Minitab, ReliaSoft, XLStat, and perhaps other statistics programs offer the Kaplan-Meier nonparametric reliability estimator as a default. Take credit for using nonparametric reliability estimation and avoiding unwarranted assumptions. What could go wrong using the Kaplan-Meier estimator?

  • Cohorts could be non-stationary, random processes! 
  • Failures could be recurrent process counts, not dead-forever! 
  • Lifetime data depends on the censoring process(es); e.g., competing risks!
  • Greenwood’s variance estimator errs! Covariances are missing!
  • Alternative estimators could be more efficient than Kaplan-Meier!

Are you using all the information in data available from population data required by GAAP? If you don’t have lifetime data, use periodic failure counts. This article describes an example where the Kaplan-Meier estimator from grouped lifetime data is less efficient than using periodic failure counts, even though you don’t know which cohort they came from!

Today’s Gremlin – Cheap Charlie

Today’s Gremlin – Cheap Charlie

Today’s Gremlin – Cheap Charlie, is a well intentioned but often mis-guided Gremlin. He or she can be many people and we’ve all dealt with them before. “Cheap Charlie” is someone who truly believes that not spending leads to profits. This is one of the many gremlins we talked about when we introduced this series of articles.

Leadership Values in Maintenance and Operations

Leadership Values in Maintenance and Operations

The Importance of Having, Setting, and Living Values as a Leader

Leadership is not just about making decisions or achieving results—it’s about setting an example and guiding others toward a common purpose. One of the most powerful ways a leader can do this is by having, setting, and living values that resonate with both themselves and their team. Values are the principles and beliefs that guide actions, shape behaviors, and define the culture of an organization. For leaders in any field, including maintenance and operations, these values become the foundation upon which everything else is built. In the context of Leadership Values in Maintenance and Operations, this foundation is especially critical, as it ensures safety, reliability, and collaboration in high-stakes environments.

Back to the Basics: Brainstorming for Continuous Improvement

Back to the Basics: Brainstorming for Continuous Improvement

Brainstorming may sound like a casual conversation technique, but when applied properly, it becomes a critical tool for continuous improvement across a range of creative and technical disciplines.
In a structured environment, brainstorming enables organizations to capture a wide range of ideas, perspectives, and solutions — ideas that might never surface in a traditional problem-solving meeting.

Let’s take a step back and revisit the basics of effective brainstorming, especially its role in driving meaningful change.

What Is RCM? It’s NOT a Maintenance Plan

What Is RCM? It’s NOT a Maintenance Plan

Is Reliability Centered Maintenance (RCM) a maintenance plan?

In this short video, I explain why RCM is NOT a maintenance plan. It’s a process designed to help YOU determine the most effective proactive maintenance tasks and how often to perform them. But that’s not all! In this video I give a quick overview to answer the question: “What is Reliability Centered Maintenance?”

You start by creating a Failure Modes and Effects Analysis (FMEA). Then, you analyze each Failure Mode using the RCM Decision Diagram—one at a time. First, you assess the consequences, then you consider Condition-Based Maintenance or Preventive Maintenance. RCM also helps you formulate solutions for Failure Modes that can’t be predicted or prevented. You can develop solutions like Failure Finding tasks, procedure changes, or additional training.

With RCM, you’ll get the reliability you need, one Failure Mode at a time.

Quality Objective 4: Lessons Learned

Every failure is a lesson learned about your strategy. Thomas Edison

In this article, I will discuss how to evaluate an FMEA against the FMEA Quality Objective for Lessons Learned.

By definition, a “lesson” means “something learned by study or experience,” and “learn” means “to gain knowledge or understanding of by study, instruction or experience.”

What are Lessons Learned?

Lessons Learned are specific data from the field (or from manufacturing plant history in the case of Process FMEAs) that documents relevant information about failures, from which knowledge can be gained and used in support of future product programs. [Read more…]
