Why Do You Need An Asset Management Program?

Understanding the Business Benefits of an Asset Management Program

Have you tried to upgrade / replace a piece of equipment due to the high cost of maintenance? What about having the process stopped by procurement because they are not aligned with the high upfront cost?

While there is a generally a common goal of ensuring the long-term success of an organization, the approach is not always cohesive. An asset management program is there to ensure an integrated and cohesive approach is in place. This cohesive approach ensures the organization is working towards a common goal. [Read more…]

What is Asset Management?

Understanding the Value of an Asset Management System

All stakeholders have different perspectives, and as a result, place value on different aspects of an asset. Trying to balance all the requirements is not an easy task. Whether the requirements are performance, cost, or the level of risk. Keep in mind, that performance can not only be uptime or OEE, but the beauty of a park, or the condition of a road. This is where asset management comes in. [Read more…]

Ethics In Maintenance? Are You Kidding?

How Ethics Influence The Reliability of The Plant

Ask almost any maintenance professional in your operation what they think about ethics. Chances are the answers will not have anything to do with their job and their role in maintaining equipment.

Ethics play an important role in many professions, such as doctors, engineers, lawyers, etc. Ethics are not typically thought of in maintenance, but in reality, ethics does have a place in maintenance.

To understand where ethics fit into maintenance, you first have to understand ethics. [Read more…]

Who Is Responsible For Reliability? Everyone!

Why Your Operators Need To Be Part Of Your Reliability Program

You drive your car (almost) every day, you will immediately notice a new noise, vibration, or feel to the car. Once you detect this you would report the issue to your mechanic (or if yourself and do the repair), and he would investigate the issue. The repair would be made and the car returned to you.

This same approach is what should be happening in your plant. The operators of the plant equipment, operate the equipment every day and know the equipment. Any changes or variation in the equipment or process would be noticed by them and should be reported to the maintenance department.

Based on this approach that we use every day with our cars, why is it that in many plants the operators do not notify maintenance of changes? Or the notifications go unused or not acted on? [Read more…]

What Can You Do With Data?

A Question & Answer Period with Fred Schenkelberg and James Kovacevic on what can be done with your data and analysis.

Data and the analyses that use the data can be tricky to manage at best, let along extremely difficult.

In this last post of the series on using the maintenance data you have, Fred and James will answer many of the common questions asked about data and the analyses. [Read more…]

The WHAT and, More Importantly, The WHY of the Weibull Analysis

How to conduct a Weibull analysis and the questions the analysis will generate.

Every failure is part of a puzzle. The equipment we are maintaining is trying to communicate with use with each and every failure.
Often the message is not obvious.

There is the immediate failure. And, if we’re paying attention we can sort out the root cause of the failure along with replacing or repairing the damaged parts. Sometimes though the damage is caused by another issue with the system.

Something was hidden. [Read more…]

Using the Maintenance Data You Already Have

Leverage the existing data in your CMMS to make sustainable improvements to your maintenance program

Let’s face it, your technicians have been entering data into the CMMS for years, but you haven’t been able to use it to make improvements. Is it because the data isn’t codified or it doesn’t have the right data points? Generally, this is how most maintenance managers will view their data, but it is incorrect. The CMMS does have data that you can use almost immediately. [Read more…]

How to Sustain the Culture Change

The key to keeping a culture change from going back

One of the reasons that culture changes fail to change and stay that way is because there is nothing put in place to sustain it. When there is no plan to sustain the change, it will be a flavor of the week and revert back to the old ways. This is the final installment of a series on culture change and if you haven’t already, please go to the first post and start there. [Read more…]

The Actions To Accelerate Your Culture Change

Hit the ground running and embed the culture change to achieve maximum results

Your culture change has a plan, it has the right people in place, and you are ready to roll it out. Your change stands a better chance of success than most change programs as you have a plan with the right people. Sometimes changes fail because the change is not embedded quickly, people lose interest and go back to their old ways. If you haven’t already, please start at the beginning of the series with the warning signs that you need a culture change. [Read more…]

Getting the Right People on the Bus and In the Right Seats

A guide to ensuring your department will support your reliability culture

People are the heart of any maintenance reliability program and they have the ability to make the program succeed or fail. This is why managing the change to reliability culture is critical. We covered a few of the key pieces to change management in the previous post. But sometimes, not matter what change management technique(s) you use, the change may not be successful. [Read more…]

Building a Reliability Culture

Laying The Groundwork for a Successful Change.

It turns out that you have been deploying the right reliability tools and maintenance practices, but the organization’s culture was preventing or hampering the results. This is a common scene played out in many organizations, but there is hope. The culture change will be a long road, as cultures are not changed overnight. [Read more…]

Red Alert: Your Culture Is Hurting Your Reliability Efforts

The Warning Signs That You Need a Culture Change

Imagine working within (or maybe you don’t need to imagine it) an organization in which everything is completely reactive. You arrive early to try and organize the work for the day, yet only to find out someone else is there doing it. [Read more…]

Learning from A Failure

Why Failing Can Be Good and What You Can Take Away from It.

Regardless of how good a maintenance & reliability program is set up and managed, there will be failures. This is partly due to the maintenance program itself, where the focus is on the consequences of the failures, not the failures itself. This approach allows most organizations to manage large facilities will a minimum of staff and cost.

But what should happen when something does fail? Should we just carry on as usual since we avoided the consequences? Absolutely not. When a failure occurs, we need to learn from it and improve the maintenance & reliability program. Yet, many organizations address failures by implementing a PM routine. This is not the right approach. Remember only 11% of failures are age-related. Adding these PM routines to the program will cause a collapse of the program from too much work, not to mention the maintenance induced failures that result from it.

So what should happen? The failure should be analyzed and actions implemented to reduce the chance of the failure occurring again.

A 2-Step Process to Improve Plant Performance

A Simple Q&A Can Reap Improved Performance in Any Activity in Maintenance.

A failure has just occurred on a critical asset in your facility. The result was 2 hours of lost production, but it could have been worse. The last time that the equipment failure occurred it took 5 hours to repair. Why was the failure repaired in less than half the time than the previous occurrence? How can we ensure that we learn from this failure and the team’s performance to improve the plant performance?

I remember reading about a simple philosophy quite a few years ago (although I can’t remember who stated it, so I apologize that I cannot provide a reference), about a simple analysis that can be applied to any maintenance activity to improve performance. This analysis is call the 2 Up / 2 Down analysis.

The 2 Up / 2 Down analysis is quite simple and involves asking two questions.

Step Change Your Plant Performance with Defect Elimination

Why Preventative Maintenance Alone Will Not Drive a Step Change in Your Plant Performance and What You Can You Do About It

Many organizations try to improve performance by just creating PM routines and letting the technicians loose to perform the work. This often has negative effects on plant performance. This has been proven through studies conducted by Ledet at numerous DuPont sites. This study looked at the impact of Planning, Scheduling and Preventative Maintenance on Plant Performance.

Ledet had found that by just implementing a PM / PdM program, organizations lost 2.40% of uptime (on a baseline of 83.50%). Not quite the results to expect when implementing a strategy to improve plant performance. When the PM / PdM program is implemented with Planning & Scheduling, the plant saw an increase of 5.10%. Now that is an improvement.

But what about the remaining 11.40% of uptime? How does one address the remaining downtime?
