Today we look at a couple different ways to visualize the distribution of your data.
Understanding the distribution of your data can be useful for engineers undertaking various tasks. The fact of the matter is that there are many different ways in which one can get an idea of the distribution of the data they’re interested in, one of which is density curves.

When you are driving on a highway, usually there is a speed limit. If you exceed this limit, a cop can give you a ticket.
In Houston, most highways have a speed limit of 65-70 miles per hour…although most drivers appear to assume it implies “90-mph is okay”.
Let us say the city of Houston were to remove the speed restrictions.
Instead they put forward the mandate “drive safely”.

So long as there are products and services offered by an organization, there will be the existence of a sales force.
The basic fundamentals of selling are simple: a customer expresses a desire for something and, in turn, someone sells them a product or service to address that desire. Essentially, sales are how an organization converts a “want” into a “need.” While these fundamentals are timeless, they are rooted in a reactive process.

Why is extreme wear occurring on the backing plate behind the impellers of these centrifugal pumps used for irrigation pumping service?
Engineering investigations into the causes of wear, erosion and metal loss on the back-plates behind the impellers of two year old centrifugal pumps pumping water about an irrigation system

There are two main ingredients for a successful reliability centered maintenance (RCM) analysis:
By 1792, six Royal Navy dockyards employed about 1500 workers each. The dockyards had a wider variety of technical specialties than was found in any other manufacturing enterprise. The dockyards “were some of the largest manufactories in Europe and dwarfed almost all private industries.” (Morriss) The dockyards built new ships, but maintaining ships was just as important. The Royal Navy’s dockyards constituted one of the largest industrial maintenance organizations in the world…and their only peer organizations in terms of the scale of maintenance management were the dockyards of other superpower navies.

Generally speaking, 5-6 things have to go wrong for an incident to occur. Furthermore, these events or failures have to occur in a certain sequence.
The characteristics of mega disasters is that 5-6 events with fairly low probabilities of occurrence line up.

Fist to five voting is a simple and effective way to gather group feedback or to gauge consensus in a meeting or discussion. In this method, participants are asked to rate their level of support for an idea or proposal on a scale of 1 to 5, using their fingers. However, fist to five is a decision-making technique that should be described in the project charter and agreed upon by all participants. Ample time should be allowed between the initial poll and the final vote for negotiation and agreement to occur. [Read more…]
Some common reasons why requirements can cause risk to a project are:
This paper explains how poorly defined requirements can impact the project.
The duties of the engineering manager role usually include capital project management and maintenance management, two vital aspects that must be done exceedingly well in an industrial operation.
My wife says I am wasting my time trying to change reliability statistics, so I polled the www.linkedin.com Reliability Leadership…, ASQRRD, IEEE Reliability, “Biostatistics, and No MTBF groups. The polls claimed that “Life data, censored or not, is required to estimate MTBF, reliability function, failure rate function, or survivor function. TRUE? FALSE? or DON’T KNOW.” I am grateful for the responses.

It is expected that the rule will be promulgated sometime this year (2010).

This is the “C” in what is called FMECA: Failure Mode, Effects and Criticality Analysis. I’ll shorten Criticality Analysis to CA in this article.
What is Quantitative CA? When and why it is used? Can Quantitative Criticality Analysis be used in commercial applications?
Facilitating with FINESSE: How to Guide People to Powerful Business Solutions is a practitioner’s guide for ten common applications that technically trained professionals are frequently asked to facilitate. The range of applications covers quality and reliability techniques such as block diagrams and tree diagrams through master plans and strategic plans. This article provides five impactful elements for professionals who are often enlisted to lead teams to workable solutions, despite having little or no facilitation training,
The book focuses on ten practical applications and provides specific ways to facilitate them better. There is not a lot of wasted time on the basics covered by most facilitation books. Each self-contained application includes examples – good and bad – from my experiences on some complicated and controversial projects.

A presentation slide set titled “Simpler Industrial and Business Process Redesign”. Presented by Mike Sondalini to The Institution of Engineers, Malaysia, Electrical Engineering Technical Division.
The presentation opens with examining three universal business problems:
He also explores the implication of the quality loss function and then incorporates the concept of maintenance work quality. Then Mike explore specific steps you can implement to improve the fundamental processes within your organization.
