One of the common questions teams have when they first explore using Predictive Maintenance is “Is the data good enough to perform the analysis?” Answer to that question is nuanced with the reliability objective and the quality of the data available.

Let a Plant Wellness Way EAM System-of-Reliability halve your Annual Maintenance Costs
The Plant Wellness Way is business paradigm to create world-class performance and results in any operation by the correct selection and use of engineering, operating, maintenance, and reliability strategy and practices.
The six IONICS steps are used to develop lifecycle asset management, reliability improvement and maintenance management strategy and activities needed for endless operational excellence. Simply identify where you are in the above process map, come in at that point, and then continue on through the process to the point where your answers are available.

Strategic alliances are a vital tool to driving growth by enabling access to external capabilities. They are collaborations, partnerships, or joint ventures whereby organisations, or partners, work together for a common purpose to achieve a common business benefit or purpose.
As much as strategic alliances are an important tool to drive growth and deliver needed capabilities, they are not without their challenges and risks.

Are generic lists of failure information useful to FMEA teams? Are they a good idea or not?
There is a lot of discussion amongst FMEA practitioners on automating and standardizing FMEAs. In this article, I will discuss the pros and cons of using generic lists of failure modes, effects and causes.
The Oxford English dictionary defines “generic” as “characteristic of or relating to a class or group of things; not specific.” [Read more…]
Assets typically age over time, leading to degraded performance and loss of function. Asset life models are built in order to predict future degradation patterns. Those models are based on asset degradation variables such as time or usage. Those variables could be for example, time between failures or distance covered between failures. Many assets have more than one degradation variable. In this case, it is important to define which of the multiple variables is the dominant one and will subsequently provide the Reliability Engineer with the most precise life model.
Reliability is a probability. Specifically, the probability that a system will perform its intended function within a specified mission time and under specific process conditions. Therefore, most reliability calculations incorporate a time element as a degradation variable. Generally, when building life models, we default to using calendar time as it is more straightforward. We have had tools to easily measure elapsed calendar time for centuries now. [Read more…]
Climate change is universally accepted. And when I say ‘universally,’ I mean that the only people who think it is not a thing are fringe elements of society who are predisposed to specific interpretations of religion or commercial greed that would be harmed by any attack on fossil fuels and the energy we derive from them.
The good thing about this is that organizations who are serious about being successful and profitable can’t do so by sharing the ideology of a small minority. More and more people (including younger humans who will be the decision makers of tomorrow) are demanding more and more from the organizations they buy services and products from – especially when it comes to environmental concerns.
So to be successful, you need to take this stuff seriously.
FINESSE is a cause-and-effect approach for effective communication when there are high levels of complexity and uncertainty. Said another way, FINESSE is an approach used for big, strategic decisions that take months or years to make. FINESSE facilitates the memory of effective communication: Frame, Illustrate, Noise, Empathy, Structure, Synergy, and Ethics.
Major decisions that take months to resolve, require a significant amount of investment, and involve many people (and some calculations) have complexity and uncertainty. These are the situations where trusted advisors need FINESSE. [Read more…]
The falling cost of sensors for Industrial Equipment & the popularity of AI-based solutions means that Organizational teams are defaulting to using this strategy on all their Equipment, regardless of its criticality or other effectiveness. This is a strategic error.

You must select OHS risk management mitigations appropriate to a job safety hazard using a formal method that delivers safe work practices.
Each task safety control will need to be developed, assessed for suitability, and recorded so it’s clear what the plan is, and how it is to be done.
In the end, there is a practically designed, completely resourced, fully scheduled, and totally sure safe work practice procedure approved for use.

Risk…it’s everywhere whether the risks are known or unknown, foreseeable or unforeseeable but, as the saying goes, “one person’s risk is another’s opportunity”.
Within this risk-opportunity spectrum we have the risk averse, the risk seeking as well as those who purport to manage risk for their business or personal lives.
We also have those who believe that risk is something that happens to other people and those who believe that Murphy’s Law will always apply to them, always, at all times, and in every circumstance.

Generations of products have similar field reliability functions because they are designed, processed, shipped, sold, and used in similar environments by similar customers. Replacement parts have similar reliability functions depending on replacement number: 1st, 2nd,….
Biostatisticians use David Cox’ proportional hazard (PH) survival function models to quantify effects of treatment or risk factors. Proportional hazard models could describe product’s failure modes, parts’ reliabilities in successive replacements, or products’ reliabilities in successive generations. [Read more…]
As engineering professionals, we’re no strangers to complex problem-solving scenarios that demand rigorous analysis, innovative thinking, and efficient decision-making. Whether it’s designing new components, optimizing processes, or addressing infrastructure challenges, our success hinges on our ability to approach problems with a structured and creative mindset.
One method that can significantly boost our problem-solving prowess is the “Six Hats Method” – a systematic approach that allows us to don different thinking hats, unlocking diverse perspectives for comprehensive and effective solutions. Let’s see how the Six Hats Method can empower engineering professionals to navigate challenges with clarity, focus, and ingenuity.

In a number of my previous blog posts, I have emphasized the disturbing trend of fires and explosions in the biodiesel and biofuel industry.
Based on the statistics, the biodiesel industry in the US is experiencing an incident every two-and-a-half months, i.e. approx. 10 weeks.
