Much has been written about James Reason’s original Swiss Cheese Model described in his book Managing the Risks of Organizational Accidents. Figure 1 is a basic representation of this model. Many today consider this model to be obsolete because of the evolving complexity of systems due to emerging technologies. Therefore, the linearity of failure expressed in this original model, is not as applicable as it was when introduced.

Keeping it honest, layoffs suck.
They suck for the targeted employees and they suck for their immediate supervision and management.
In 1981 I was hired by our area’s largest employer at the time as an incoming apprentice. The day I was hired my soon to be wife and I celebrated she as a schoolteacher and I now had lifelong employment. We could now get married, buy a home, and start a family. In three years it took for me to complete my apprenticeship and for her to complete her master’s in education, we did just that. Life for this young family couldn’t have been better.
And then the layoffs started.
Things get a little dirty when humans get involved. In any system, human behavior and human understanding “gum up” the process. These are a few of the dirty secrets for effective communications.
Communication is the exchange of information from one person to another.
Communication requires a sender, a receiver, and a message. Technical professionals (sender) usually believe the decision maker (receiver) cannot understand the message because the decision maker is not as smart as they are. Most of the time, the lack of understanding comes from the noise generated by the sender. The burden of effective communication is on the send (technical professional), not the receiver (decision maker). [Read more…]
My contention is management many times compromises quality to mitigate budget and cost issues resulting in a major risk to the project.
How to minimize the quality risk on a project is addressed in this paper. The approach to do this is based on my 30 years of project and project risk management experience and knowledge. Let’s start with a story to illustrate my contention.

We love great success stories: The wizard entrepreneur; the person who crusaded for a worthy cause; the champion athlete; the financial guru; the innovative business solution with astounding results; the failing firm that turned their fortunes around; the penniless emigrant whose wits made them wealthy. Those stories are inspirational. They challenge us to be better. They make us want to achieve more in our life roles and with our lives.

Covid scared us all! Here you can see two Red Pandas with their version of a threatening response. When threatened, we will have one of three reactions – fight, flight, or freeze.
Our businesses also have similar responses. A few have fought – and they “pivoted.” Some fled – they folded up and went away. Many simply froze – they halted just about everything. If your business froze, then this article is for you.

Asset reliability programs are a set of initiatives for tracking the health, effectiveness and locations of both fixed and moveable assets. It involves routine maintenance, as well as the collection and analysis of equipment operating data to measure efficiency throughout their useful lives.
A good reliability engineering program provides insight on the frequency of asset failures, cost of operation, maintenance and repair, and the quality of maintenance work. Over time, an organization needs to evaluate metrics such as mean time between failures (MTBF), mean time to repair (MTTR), and mean time to failure (MTTF) to ascertain the suitability of the selected maintenance strategy.

Reduce data entry time and costly errors while boosting productivity by integrating your facilities management software with barcoding technology. Many vendors are offering this technology for facility maintenance software as an included feature or add-on to improve the timeliness and accuracy of data input in their CMMS/EAM systems.

When facilitating a Root Cause Analysis (RCA), the proper questioning process will make or break the effectiveness of the entire analysis. When we hear of the 5-Why’s as a valid RCA approach, is simply asking ‘Why?’ 5x good enough….or IS IT JUST OK?
Think about it this way, if I asked you ‘How Could’ the crime have occurred versus ‘Why’ the crime occurred, would your answers be different?
I am going to take a very basic (101) case study and format it using a logic tree (graphical expression of cause-and-effect logic). As we are guided through this mental process we will discuss the differences between asking ‘How Can?’ and ‘Why?’.

Data is good. Quality data is better. “Big data” is even fashionable. But it won’t help you solve a “small data” problem.
Let me guess. The quality of your CMMS data is not great, but if it was, you could really do something with it. Since decades, in fact. Just need to re-tweak those failure codes!
And recently, you were very tempted by a consultant’s new “data-driven” approach that promised to deliver staggering results. And why not?
Because it’s not a “big data” problem.

Effective communication is the one thing that makes your life better, more fulfilling, and more rewarding. That is equally true in personal relationships and in business.
Keep it simple. If you can convey the same information in fewer words, do it. If you can use fewer sentences, use fewer. If you can avoid tangents and parenthetical comments, avoid them. Only about 20 percent of what you normally communicate provides 80 percent of the influence on others.

The one thing is right under your nose. The one thing is the game changer for your career because it enables others to understand the complex and uncertain world where you work. The one thing requires understanding the outcomes you seek before optimizing the separate components.
A system is a collection of interrelated or interacting parts, each of which can affect the behavior or outcomes of the whole. One defining property of a system is that it provides a function that none of the parts can accomplish by themselves. The corollary is that a system is not the sum of the parts but the product of their interactions.
Simple examples include the mechanical advantage gained from a system of pulleys or a gearbox. Sports teams or work units are examples of human systems. Systems are essential aspects of our everyday lives.

Many people have a few smoke alarms dotted around their house and, to me, these are some of the most straightforward set-it-and-forget-it risk management tools you can get. You set these up and then…nothing. You can forget about them until that annoying ‘chirp’ sound wakes you up one night, telling you to change the battery.
And most people will never hear their smoke alarm go off except for those times that their cooking gets a little out of hand.
However, if there were a fire, they’d know about it immediately and be able to react.

The prime role of Maintenance is to reduce operating risk. Maintenance serves a business well when its use leads to lower production costs than using other choices that could have been taken. Too many managers think that they must maintain plant and equipment. Maybe you do and maybe you don’t. Maintenance is expensive and, as far as it is safe, use less costly answers. But if you do choose to do maintenance, then you ought to pick an operation’s maintenance strategy mix based totally on its effectiveness in delivering the least operating costs for the least maintenance cost.

Get it right on paper before attempting to computerize and automate.
The Work Management Process. One of the biggest uses of IIoT, ML, and AI in the industry (so far) is in the field of condition monitoring and forecasting times to failure. IIoT devices deployed on your equipment and systems, send exception signals (they use edge computing to filter out the vast majority of the data that merely tells you “all is well”) over some sort of network (usually wireless), then some sort of software interface produces a message for you to read (maybe triggers and work request, or sounds an alarm) and then act on.
