Eight Ways to Keep Reliability Engineers From Leaving

Eight Ways to Keep Reliability Engineers From Leaving

A topic that often comes up lately is high turnover, especially the perception that this is common and desirable among millennials. Born in the mid eighties, I am right on the cusp between millennial and Generation X, and I am one of the aforementioned employees with a high turnover history. A specialized Reliability Engineer with nearly ten years of work experience, I have rarely stayed with a company much over two years. I never intended to be a person who moved between companies so regularly, it just kind of happened.  [Read more…]

Mathematical Models, Algorithms, and Risk Management Methodologies

Mathematical Models, Algorithms, and Risk Management Methodologies

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

Introduction

We are enamored by risk models, mathematic algorithms, equations and formulae.  As a matter of fact, we have become so enamored by complex mathematical algorithms, formulas, models and derivatives that we have abdicated much of the analysis of risk, to these complex formulas and quantitative analysis methodologies touted by firms far and wide.  Where has this gotten us?  Are we better able to predict and measure risk exposures?  Are we managing risk more effectively?

Static Electricity Basics

Static Electricity Basics

Static electricity is the build-up of opposite polarity (positive and negative) electrical charges on two different substances in contact by the movement of one surface across the other. The spark that can occur from static build-up is the result of the opposite charges neutralising themselves when the electrical field between them becomes strong enough to overcome the gap resistance.  [Read more…]

The 2 Parameter Lognormal Distribution 7 Formulas

The 2 Parameter Lognormal Distribution 7 Formulas

This is part of a short series on the common life data distributions.

The Lognormal distribution is a versatile and continuous distribution. It is similar to the Weibull in flexibility with just slightly fatter tails in most circumstances. It is commonly used to describe time to repair behavior. This short article focuses on 7 formulas of the Lognormal Distribution.

If you want to know more about fitting a set of data to a distribution, well that is in another article.

It has the essential formulas that you may find useful when answering specific questions. Knowing a distribution’s set of parameters does provide, along with the right formulas, a quick means to answer a wide range of reliability related questions. [Read more…]

The Perfect Reliability Program

The Perfect Reliability Program

An executive asked me how to make a “perfectly reliable product.”

I told him that program would look a lot like an embarrassing market failure that could put a company out of business.

This was not the response he was expecting.  I chose to elaborate before he just walked away.

The investment of time, dollars, and man power to create a “perfectly” reliable product would force such a compromise on all other aspects of the product and program that any type of market success would almost be impossible.  I can only think of two types of products that could benefit from an approach of creating perfect reliability. The two I am thinking of are the Mars Rover ‘Curiosity” and a nuclear power plant. The desire for “perfect reliability” would be driven by either an avoidance of massive loss of life (not just a few lives) or loss of billions of dollars by a single failure mode.

Reliability Engineering is About Answering 3 Questions

Reliability Engineering is About Answering 3 Questions

Engineers solve problems. We optimize solutions.

Engineering starts with a question. The work of engineering is answering those questions. Can we create an antenna with enough range? How can we make a safe autonomous driving car? How much can a delivery drone carry if it has a range of 100 miles?

Reliability engineers are no different. We ask questions and work to answer them. To solve the problems in the pursuit of providing our customers reliable solutions.

In general, there are only a few types of questions a reliability engineer addresses: What will fail, when, and what is the impact of a failure.

The answers are used to design reliable products, optimize supply chains and assembly processes, refine warranty accruals, and identify significant business risks. [Read more…]

Enabling Customer Value in Product Design

Enabling Customer Value in Product Design

Use an Integrated Approach in the Product Life Cycle Process to Enable Customer Value

Given our primary goal of developing a profitable product, our objective in the design process is to maximize customer value and minimize cost.  From a financial analysis standpoint: we pursue products with the highest possible margins (ie. charge the customer “as much” as possible, and make the product for “as little” as possible).  Of course we also want to sell “as many” as possible.

How Accounting Policies Affect Maintenance Costs

How Accounting Policies Affect Maintenance Costs

Accounting decisions can greatly affect maintenance costs. Two examples are the decision to purchase items as maintenance or capital and plant item asset numbering.

Maintenance costs are expensed in the financial year incurred and are claimed as a tax deduction at the company tax rate (soon 30% in Australia) in the year they are spent. Capital expenditure, on the other hand, is depreciated and can only be claimed as a tax deduction over the usable life of the equipment. Depending on the industry, the depreciation rate for industrial equipment is 20% per year. It can be as little as 2.5% per year for office buildings. There is a clear tax advantage to claim as much expenditure as possible as a maintenance cost and not a capital cost.  [Read more…]

Heightened Awareness or Reactive, Backwards Looking?

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

From financial crises to energy catastrophes to earthquakes and threats of terrorism, we hear a lot about events that challenge our ability to identify and manage risk.  Unfortunately, some of the things that emerge from many of these events are reactive regulatory rules and requirements.

10 Things a Maintenance Tech Can Do Today to Improve Reliability

10 Things a Maintenance Tech Can Do Today to Improve Reliability

As companies around the globe look to improve equipment reliability, I can’t help but think of the Technicians and Craftspeople I meet after conference presentations. As they step up to introduce themselves to comment on the presentation, these attendees will often say, “I really liked your presentation, but I don’t think our management would ever support a program like this. What you are doing makes a lot of sense, but we just don’t have the people and our Operations Managers don’t understand maintenance and reliability.” [Read more…]
