ERM Implementation Requires Culture Change

Guest Post by John Ayers (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

Enterprise Risk Management (ERM) is a relatively new concept (been around 10-12 years). It is a top down approach to business system management and execution It is a risk-based problem solving and decision-making process. Everything is looked through a risk prism.

I suspect that many of the companies that have adopted ERM have not implemented it to the fullest extent of its capabilities. The reason is it takes a cultural change to do so and many companies do not know how to do it. This paper by example explains how to change the culture in a company to fully and completely implement ERM. [Read more…]

Asset Prioritization and Criticality

Asset Prioritization and criticality are used to provide a structured approach to determining the relative organizational risks and failure consequences associated with assets. This provides a means for the organization to focus on critical risks to the business.

Asset Management Systems for Small Groups

An asset management system is comprised of all of the necessary processes, procedures, tools, systems, and methods necessary to meet business objectives in a manner which is controlled, measured, and improved upon. The system, more often than not, takes on some visual representation as in the graphic below. The purpose is to provide a simplified understanding of the overall process to meet asset management goals.

How do I Implement SPC for Short Production Runs (Part II)?

In Part I of this article, we introduced the concept of utilizing Deviation from Nominal (DNOM) control charts for short production runs. These charts allow us to monitor process characteristics over time even when the units being controlled have varying nominal values. DNOM charts assume that the process variability (i.e. standard deviation) does not vary significantly by part type. However, often this assumption does not hold. Characteristics with larger nominal values tend to have more variation than characteristics with smaller nominal values. In Part II we discuss how to test whether or not significant differences in variability exist and if so, how to modify the DNOM methods and charts to handle this situation. [Read more…]

Should We Call it Precision Maintenance?

I got a call last week from a friend I used to work with who called just to catch up on what I had going on in life. After a few minutes of conversation on what each of us had going on he asked me what I thought of the phrase “Precision Maintenance.”

I must admit, I was a bit confused by the question. I told him I think a lack of precision maintenance might me the leading cause of failure for nearly every company in the world. I don’t think we spend nearly enough time training and certifying tradespeople in precision maintenance techniques and that the reduction in skilled trades apprentice programs has made the problem worse.

How Failed Parts Work Into an RCA

Author’s Note: I want to reiterate that this Series about reading the basic fracture surfaces, is for novices who often come into contact with such failed components. This Series is about the basics (101), and is intended to give readers an appreciation for the value of such ‘broken’ parts to an effective investigation/RCA. While this information will be rudimentary to seasoned materials engineers/investigators, I know they will all appreciate heightening awareness to the need to retain such failed parts for formal analysis, versus throwing them away and just replacing the part. Throwing away failed parts is a recipe for a repeat failure. When one does not understand why the part failed in the first place, they can’t prevent it from failing again.

In this article we will focus on how to actually incorporate the evidence (failed parts) from a failure, into a disciplined Root Cause Analysis (RCA) process.

Who Owns the Storeroom? Maintenance or Procurement?

Understanding who owns the storeroom processes and stocking strategy

There are two different perspectives on the maintenance storeroom. These perspectives are on who owns the operation of the storeroom. Some believe that Maintenance owns the storeroom and the operation of it. Others believe it is Procurement, or potentially Logistics or Warehousing. Some organizations require the storerooms to be operated by a consistent group, while others leave it up to the site.

Change and Resistance Are Futile

Guest Post by Malcolm Peart (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

Organisations exist in a dynamic world where business uncertainty and socio-political volatility can adversely affect their existence. The mass of data available and the contradictory interpretations that can be made add ambiguity and complexity to the mix. Our modern day organisations, or at least their management or leadership team realise, or should realise, that their operating environments are changing and, in order to adapt and survive, they too need to change.

Asset Management is more than Maintenance

Asset Management is more than maintenance and reliability, yet many often think they are the same. Asset Management is far broader and considers the entire life cycle.

How does your organization differentiate between asset management, and maintenance and reliability?

Early in the discussions around asset management, some organizations simply renamed their Maintenance and Reliability departments to Asset Management departments, even though they continued to do the same tasks and activities they always did.

Analyzing the Experiment (Part 6) – Prediction Uncertainty and Model Validation

In the last Article, we explored the use of contour plots and other tools (such as a response optimizer) to help us quickly find solutions to our models. In this article, we will look at the uncertainty in these predictions. We will also discuss model validation to ensure that technical assumptions that are inherent in the modeling process is satisfied. [Read more…]

Failure Analysis – The Big Picture

The floating drilling rig, operating in 6,000 ft. of water, pitched in rough seas 300 miles away from shore as the outer bands of the hurricane’s winds buffeted the drilling location. Per procedure, the crew installed the Storm Packer (SP) in the well to isolate its open wellbore from the ocean before the storm roared across the location – but it failed its pressure test. The crew then installed the back-up SP which passed the pressure test. The well was finally secured, and the 25,000-ton drilling rig was moved out of the hurricane’s path. Because the first SP failed, a 12-hour process took 30 hours to complete, while wind speed and wave heights increased.

Tips for Examining Shafts: Prepping for a Root Cause Analysis

To those following this Series, I will apologize for the front-end redundancy. I am doing so for those that are NOT following the Series and will read these articles independent of each other. If you are following the series (Thank You!) and proceed past the front-end stuff and to the shaft pics below:-)

Abstract. In our last series highlighting the 4 primary Failure Modes (FM) of component failures (erosion, corrosion, fatigue and overload), we discussed how to read fractured surfaces. In this follow up series, we will take a look at tips on how to collect, preserve and examine such failed components.

Learning to Crawl, Before You Can Walk and Run

Some Insights into the Current Status of Maintenance & Reliability Fundamentals

Let’s face it, we as engineers, maintenance staff, etc. all love technology and the newest gadget. Our industry is never short of these new and shiny techniques, tools, sensors, etc. Now, this new tech can lead to significant improvements in availability, OEE, or uptime. But these are not the silver bullets many claim them to be… especially if the foundational elements are not in place.

How Less Data Can Give You Better Results

Guest Post by Andrew Sheves (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

“Hi, I’m Andrew, and I have a weakness for data.”

There, I said it.

I love spreadsheets. I love national statistics. I love primary sources.

I could probably have completed my Master’s dissertation without an extension if I had just accepted that cited quotes were valid instead of looking for all the original sources*. And I don’t need to read the last three years of a company’s annual reports before I have a 20-minute call with them.
