The Basics of Planned and Deferred Maintenance

The Basics of Planned and Deferred Maintenance

We can plan to do more than we are capable of accomplishing. The remaining items, if they warranty accomplishing become deferred. They roll over to the next’s day’s list of actions to take.

Of course, in practice, the process to plan, execute, and defer maintenance activities is a bit more complex than described above. The ability to maintain equipment in working order along with minimizing downtime and costs is in large part the balance between resources available to conduct maintenance and the increased risk of system failure due to deferred maintenance.

Understanding FMEA Detection: Part 1

Understanding FMEA Detection: Part 1

Can You Find a Needle in a Haystack?

Failure modes and their causes can be detected in service, like tire pressure monitors on your vehicle. Is that what is assessed in the Detection column of the FMEA? This article discusses detection risk, including examples, and answers this question.

Gear Pump Operation & Maintenance

Gear Pump Operation & Maintenance

A gear pump uses two meshing, toothed cogs to force water from the inlet of the pump through to the outlet. Figure No. 1 shows a simplified drawing of an external teeth gear pump on the left along with the alternate arrangement of internally pointing teeth. [Read more…]

Phase and Gate Structure for New Product Development

Phase and Gate Structure for New Product Development

In previous articles we defined an element of lean as a phase and gate structure for new product development.  This assumes a waterfall approach to the project (versus agile product development).

A new product life cycle phase gate structure might entail, for example: “Definition, Concept, Design, Verification, Qualification, Production and End-of-Life”.  (Your organization might decide on different phase names.)

There’s an apparent contradiction in using a waterfall project approach and calling it lean project management, however.  A goal of any lean process is to work toward ‘single piece’ or continuous flow: agile product development is more like ‘single piece flow’ of information, versus waterfall which is more like ‘batch processing’ of information.

It’s Time To Bring Back Skilled Trade Apprentice Programs!

It’s Time To Bring Back Skilled Trade Apprentice Programs!

As I work with teams of operators and skilled trades people performing RCM analyses at companies around the world at some point in time as we are discussing the failure modes and effects I might ask the question; how does your company ensure that the skilled trades people working on your assets are actually qualified to work on the equipment?

This question is often met with a look of confusion. [Read more…]

Fail Fast – Fail Small – Learn and Move On

Fail Fast – Fail Small – Learn and Move On

Guest Post by Joseph Paris (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

Fail Fast – Fail Small – Learn and Move On

Nobody likes to fail. Failing causes us embarrassment. Failing bruises our ego. Failing might be a dark spot on our performance assessments. All we have to do is reflect on our childhood for when we failed and how poorly we felt. Even if our parents did give us encouragement, we still felt bad about failing. Let’s face it – failing sucks.

Tools to Focus on Plant Reliability

Tools to Focus on Plant Reliability

The focus of maintenance has changed from repairing equipment to keeping it running for longer between breakdowns. This requires more consideration of how to get longer running life between repairs, i.e. higher reliability, on a machine. To accomplish this a number of ‘tools’ have been invented and developed to allow maintainers to pinpoint problems and fix them. In this article three of the most effective ‘tools’ will be introduced. Root cause analysis, Weibull analysis and lifecycle simulation can be used to help organisations achieve proactive approaches to maintenance or adopt a “reliability based approach” to maintenance.  [Read more…]

Data Outliers and Questions

Data Outliers and Questions

When looking at a pile of data, sometimes there is a data point that is not like the others. It attracts attention as it is different than the rest of the data.

When I spot something odd in a dataset, I wonder if there is something to learn here. Is this an opportunity to make a discovery or improve a process?

All too often it is tempting to remove the outlier as a mistake. Or to drop the outlier as it doesn’t make any sense and ‘messes up’ the analysis. [Read more…]

Lean Project Management for Product Development

Lean Project Management for Product Development

My last article covered a scalable model for lean product development depending on the number of projects and technical objectives.

Let’s start with the foundational elements from this model:

 

  • Facilitate a lean project
  • Understand customer needs (requirements validation and/or agile product development)
  • Maximize customer (product) value (product value estimation)

What is the Best Approach to Negotiating Salary?

#AskAsh – 003 – How to Confidently Enter a Job Offer Negotiation?

In this article, I answer one engineer’s questions regarding how to squash his nerves with a job offer negotiation.  His question specifically asks about salary negotiation. However, as you’ll read in tip #6 below, it is better to focus on the whole package and consider other aspects of the offer that might be more important to you.  [Read more…]

Reliability in the Business Case

Reliability in the Business Case

The challenges of keeping reliability at the resource and schedule negotiating table mid-program  can be greatly helped by a solid effort to connect it to the business case when the product program is created.

It’s the ambiguity of how reliability makes the company money that makes the case in live negotiation so difficult.  Everyone knows that reliability affects sales, marketing, warranty expense, future development.  But how do you compare that to the urgency of time to market or cost point?  If you, as the reliability representative, can point to a specific quantitative connection made to the business case for the product you have one.

The Two Faces of RCM

The Two Faces of RCM

I had a conference call this morning with some potential clients in regard to rolling out a RCM Blitz™ effort. The sad thing about Reliability Centered Maintenance is the reputation the tool has acquired over the last 40 years has one of two faces.

The sad, tragic and more popular face is that if the Resource Consuming Monster. The reputation that RCM is too detailed, that it takes too long, and that by the time you finish your analysis there are no recourses and there is no money left for implementation. According to a survey conducted on ReliabilityWeb.com nearly 70% of all RCM implementations fail, with statistics like this, it is a wonder the tool still exists. [Read more…]

Job Safety on Hazardous & Dangerous Work

Job Safety on Hazardous & Dangerous Work

See www.jsaprograms.com for innovation in hazard control.

Doing a job safely is no accident! Like all good outcomes safety is a result of good planning. As the Chinese philosopher Confucius said, “In all things success depends on previous preparation and without such preparation there is sure to be failure.” If you want safe work it needs to be planned as part of the job.

The other important fact about safety is that it is a personal responsibility. It is up to you to do the job safely. There is not a manager or supervisor in the world that wants to go to prison or be fined for a death or maiming because of his negligence. That means people in-charge want jobs done safely too. All they ask is that the safety procedures and practices used on the job be the least that are adequate while still meeting all the safety issues.  [Read more…]

What Does Eloquent Design Mean to You?

What Does Eloquent Design Mean to You?

Guest Post by John Ayers (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

What Does Eloquent Design Mean to You?

Eloquence has many definitions primarily applied to speaking and writing.  One definition is the art or practice of using fluent, forceful, and persuasive discourse. Over the ages, authors have variously described eloquence as “words sweetly placed and modestly directed” (William Shakespeare), “a painting of thought” (Blaise Pascal), “the poetry of prose” (William Cullen Bryant), “the appropriate organ of the highest personal energy” (Ralph Waldo Emerson), and “the art of clothing the thought in apt, significant and sounding words” (John Dryden).

I think many of these words describing eloquence can also be applied to product design.  Some examples and rational are presented below. [Read more…]
