In our previous chapters, we talked about how the topics of the three previous chapters work together. In our analogy, we’re sailing a sailboat to the North Pole.
This is done by using self-awareness as an understanding of where your starting point on the journey is, with a focus on radical honesty, as lying to yourself is as useless as not even starting to reflect.

Workplace Safety training is a big industry…every year companies are spending millions of dollars on training their employees.
I have always doubted the efficacy of repetitive and boring training sessions whether personal or virtual (Will your Refresher Training Work?). What is more surprising is that organizations are increasing their training budget without evaluating efficacy of their training program.

Opinion-based data is the foundation of qualitative assessments. Qualitative assessments are used in various applications, including asset management, risk management, human reliability analysis, and customer surveys. The usefulness of any qualitative assessment is a function of best practices associated with design, analysis, and administration.
The article provides best practices for improving qualitative assessment analysis. Facilitators develop and use qualitative assessments in the execution of their work. Facilitators should be aware of qualitative assessment analysis as they seek to bring a group of participants to solutions that are created, understood, and accepted by all.

A classic question for all CEOs and floor sweepers alike. What the heck do we do and what do we want to do? In big business there is visioning, missioning, goal setting, target measuring, market analysis, focus groups, policy and much much more, more and more. In small business, we offer far more than we would like to do, but in order to make ends meet, we take on more and more until we finally burn out or are lucky enough to realise a cash flow that will enable us to niche or focus on what we do and what we want to do.

Abstract:
The Galvanic Corrosion Trap. The wrong combination of metals can produce a corrosion cell of unequal voltage where one metal gives up its electrons and corrodes away. If the corrosion is not detected it will result in eventual failure of the equipment. Galvanic corrosion prevention is a design selection issue that one must always be aware of, as it can arise with the simplest of decisions. This article highlights a galvanic corrosion problem often seen in industry and sometimes missed by the person selecting equipment.

A reliability culture is a set of values, attitudes, and behaviors that promote the consistent delivery of high-quality products and services. It is a collective effort involving every team member, not just the team of reliability engineers. Proactive organizations prioritize identifying and eliminating reliability issues early in the production process. In contrast, reactive organizations only take action after failures occur, which can result in costly consequences, such as product recalls. [Read more…]
Among students beginning their examination of reliability engineering, one question pops up repeatedly: Where did all these reliability life models come from? On one hand, reliability engineering is deeply entrenched in statistical models … Weibull, exponential, etc. But these models alone, do not fully explain the product life models. There is still a missing piece: the Physics of Failure (PoF).
PoF and reliability models are closely connected concepts, as they both relate to the ability of products, processes, and systems to perform their intended function consistently over time. [Read more…]
I recently came across a very interesting incident involving foam concrete.
Foam concrete is produced by mechanical mixing of foam prepared in advance with concrete mixture, and not with the help of chemical reactions. At the incident site, two workers were removing steelwork using angle grinders while the foam concrete was settling. There was an explosion injuring the two workers.
Foam concrete produces hydrogen which is highly flammable.

John Fincham was master shipwright at Chatham and Portsmouth, and the superintendent of the school of naval architecture. He wrote several books about shipbuilding and construction of masts. In 1851, he wrote a history of naval architecture. His history recorded some design changes that the Royal Navy made in the 1700s to improve the reliability of its ships. These changes were important and permanent enough for Fincharm to discuss them 100 years later.

Risk is the impact of uncertainty on achieving your objectives – the impact can be either positive or negative outcomes (ISO 31000). Governments have multiple objectives they have to meet – health and wellbeing, economic, environmental, ethical and so on. Each of these objectives essentially becomes a risk endpoint. The fundamental tenets of risk assessment are understanding the system (the context), understanding and assessing the risk (against your identified objectives), managing the risk and then monitoring whether the risk is actually controlled, and whether a further risk treatment needs to be applied.[1]

We now know how to audit our time, to assess our self-leadership, but we can help even further explain how to become more effective and efficient leaders of ourselves.
The first thing we need to do is be empowered to make our own strategy. This comes with a few requirements.

Based on incident data in biodiesel facilities, I had written that the biodiesel industry in the US is experiencing an incidentevery two-and-a-half months, i.e. approx. 10 weeks.
Here are incidents following my May 2009 blog post on biodiesel incident frequency.

Opinion-based data is the foundation of qualitative assessments. Qualitative assessments are used in various applications, including asset management, risk management, human reliability analysis, and customer surveys. The usefulness of any qualitative assessment is a function of design, analysis, and administration.
The article provides tips for improving qualitative assessment design. Facilitators develop and use qualitative assessments in the execution of their work. Facilitators should be aware of qualitative assessment design as they seek to bring a group of participants to solutions that are created, understood, and accepted by all. [Read more…]
One of the more challenging aspects of FMEA is the subject of Occurrence. Part of every FMEA standard or procedure is the assessment of Occurrence based on an agreed-upon scale. Here are some pointers for when and how to use occurrence in an FMEA.
We’ll start with a definition. The Oxford English dictionary defines “occurrence” as “the fact or frequency of something happening.”
