In the field, we know that there are no “quick fixes” or “silver bullet solutions” when it comes to improvements in maintenance management. Many separate conditions and events must come together properly to achieve “schedule success” – i.e.: the high level of compliance to a schedule of planned work as produced by your planners.

Is your organization best suited for a cloud based CMMS or on-premise maintenance software? As the price of bandwidth and storage continues to decrease, cloud-based maintenance software is becoming an increasingly popular choice. Many cloud-based CMMS/EAM software vendors are pushing this technology as a convenient and cost-effective alternative to traditional, on-premise software, but cloud-based solutions aren’t necessarily right for everyone. There is no such thing as a one-size-fits-all solution, so you would be better off exploring the pros and cons of cloud-based vs on-premise CMMS options before committing to any particular technology.

Just as trees grow and change, so do circumstances that affect our equipment. That’s why it’s important to do this from time to time… [Read more…]
Graphs contain information and often tell a story. Our interpretation of the graphic can be aided or hindered by the design or style of the plot. Cleveland and McGill (1984) studied graphical perception and found the use of dot plots to aid viewers to understand the data’s message clearly.
The nature of a dot plot is like a bar chart, yet without the bars. Less ink, just a dot to indicate count or position along an axis permits conveying information simply. Due to its simplicity, it also permits adding additional information useful for comparisons or spotting trends, and more. [Read more…]
Uncertainty is another word for risk. Reliability uncertainty or risk is neither good nor bad, it just a bit unknown. Until we know the outcome, the eventual reliability performance, we will not know the impact.
So, how do we deal with reliability uncertainty? Will our product or system work as expected over time, or will it fail? Let’s examine a few of the common approaches in use and when and why the approach is effective. [Read more…]
In last month’s introductory article, we discussed some of the barriers to selling not only the concept of Root Cause Analysis (RCA) but also the recommendations generated as a result of these analyses. We also laid the framework for making better predictions by generating and accessing better data—namely predicting our Mean Time between Failure (MTBF) and Mean Time to Restore (MTTR) earlier and, therefore, implementing a fix faster.
Given this background, let’s explore how we can now justify conducting a RCA and implementing the recommendations as a result of the analysis. By and far, conducting a true RCA is viewed as luxury not a necessity. Think about the objections we hear when we offer the idea of gathering RCA teams. What follows is a list of common objections to RCA accompanied by rational justifications that any manager can employ. [Read more…]
In the article Reliability in Equipment Design it was stated that a project team can set reliability target(s) for new equipment using historical reliability data. One option OEMs have for capturing historical reliability data is a Failure Reporting And Corrective Action System, or FRACAS. The data captured can provide a comprehensive view of how the equipment is performing. This data can be used to improve legacy equipment and drive decision-making on new equipment. [Read more…]
Remember how we were told as kids in school that we had to study hard to get into college or university? There was that ongoing, implied threat that not getting into university or college would ruin our career. Or at least, be very bad.
It turns out it may not be that bad after all. For example, over half of Apple’s employees don’t have 4-year degrees. Why? [Read more…]
Why is that some organization seem to break the reactive cycle and others don’t? After all most organizations have a PM program and some form of a planning and scheduling program right? The key difference between those that do is their ability to use their failure data and systematically eliminate defects and issues from the processes and equipment. This doesn’t mean adding a new PM everytime some fails, which just won’t work.
To eliminate the defects and issues, the organization needs to collect meaningful data to analyze and act on. This is where FRACAS comes in. [Read more…]
The Coronavirus pandemic (COVID19) continues to spread throughout the world despite the best efforts of governments and the medical community. With no vaccine becoming available in the near term and perhaps even in the long term we are faced with growing uncertainty. It seems that ever since the emergence of COVID19 that conflicting advice, information and guidance has exacerbated the situation and created a lack of trust on the part of the public on what measures to take. Wear a mask.
Don’t wear a mask. Social distance. Don’t social distance. The only advice that seems trustworthy is “Wash your hands”; and, that is something that we should do regardless of the pandemic – it’s good common sense. [Read more…]
The fist part of this post you likely already know. It’s the second part that may be helpful.
I love HALT testing and almost always include it in a new program. With a team new to the concept there is always the hurdle of getting them to understand it’s value. It’s not intuitive to see value in destroying a product with stepped stresses. Often these stresses aren’t even apart of the product’s use case. Why vibrate a lab electronic device that spends its entire life on a bench? Seeing the failure mode is a capacitor flying off the PCB at 50 G’s doesn’t reinforce the value of the activity without some explanation.
You may have heard of the 80/20 rule. The idea is that 80% of the wealth is held by 20% of the population. As an Italian economist, Vilfredo Pareto made this observation that became generalized as the
Pareto Principle: 80% of outcomes are due to 20% of causes
For field returns, for example, we may surmise that 80% of the failures are due to 20% of the components, for example. This principle helps us to focus our work to reduce field failures by address the vital few causes that lead to the most, or most expensive, failures. [Read more…]
Have you ever heard that Reliability Centered Maintenance (RCM) is just for airplanes? Don’t believe it! Here’s how RCM came to be one of the most effective (and universal) Reliability improvement efforts an organization can implement. [Read more…]
Every organization needs to be able to explain ‘why’ it is here. In fact, an organization’s ‘why’ is . Check out Simon Sinek. One of his favourite phrases is that ‘people don’t buy what you do – they buy why you do it.’
People buy Apple products because of they enjoy how they interface with devices that are part of a bigger and seamless ecosystem. All their competitors try to emulate this. Amazon is all about customer experience. [Read more…]
