Making the Connection

Why do so few product development programs make that connection between the product specification document content and the released product? It seems to be such a common thing that these two don’t connect that organizations don’t even bother to review or analyze this after release.

The mindset at that point seems to be:

We did the best we could with the resources we had
All product change from their original specifications
It transformed into a product that better fits our updated understanding of what could be made to satisfy the market

4 Different Types of Reliability Testing

Getting the Right Information from Your Reliability Testing

You cannot test in reliability any more than you can test in quality. Often reliability testing is done though, and knowing the range of testing approaches and their associated results will help you get the most information from each test conducted.

Let’s explore the types of testing that generate information useful as you develop a reliable product. There are 4 different types of reliability testing:

Discovery
Life
Environmental
Regulatory

Within each type there are many variations to the testing details and the specific results generated. Understanding the questions each type of testing has the capability to resolve is a good first step to implementing the right set of tests for your project. [Read more…]

Characteristic 1 of an RCA Program

Committed Sponsor

As with other programs, an RCA program needs to be driven from the top and supported through all levels of the organization. This includes upper management, supervision or mid-management, and those on the front line doing the [Read more…]

UAV’s Coming to Your Neighborhood

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

Here in Seattle we’ve had several interesting incidents/accidents with personal UAVs (unmanned aerial vehicles) or drones.

In one case a person flew their UAV into the Space Needle, no damage and no one was hurt; at a parade an operator lost control and hit and knocked out a parade attendee and the operator was cited by police; UAV stuck on power lines over a lake, result – power turned off and UAV recovered at a cost of $35K and the operator was not found; and just recently a UAV was flown into the Ferris wheel on the waterfront, no damage to the wheel though a table on a nearby deck was destroyed.

In the first two of these cases the operators were identified and contacted by Seattle Police. No one has stepped forward in the third and fourth, and since the FAA database is not in place yet, the only means to track them may be through the manufacturer. [Read more…]

Sizing Liquid Pipelines Easily

Sizing liquid flow pipelines easily. Designing pipe work for liquid flow requires calculating the pressure losses along the pipe due to pipe friction. Once the losses are known the right pipe diameter can be selected. If full engineering calculations are not possible the conservative approach is to select pipe sizes that produce a velocity of less than 3 m/sec.

Keywords: pressure loss, viscosity, friction factor. [Read more…]

The Specialist

I was in a meeting recently with a customer team. It was on-site with 12 people ranging from mid-level engineers to upper management. Someone defended me earlier in the meeting by saying “Well, he did write a book on it!” Which was nice and kinda cool to hear someone say. But this lead to a later comeback by a crusty, principle engineer, 40 years under his belt, boat captain from “Jaws” kind of guy. “If we can buy your book then why do we need you?”

I took a moment. I knew that not responding wasn’t what I wanted to do but had to tread carefully because a poorly crafted response could easily sound arrogant. This is what I responded with… [Read more…]

4 Steps to Accomplish HALT

4 Not Always Easy Steps

Highly Accelerated Life Testing, HALT, is a method to discover the weaknesses in a design. Using a step stress approach of single and combined stresses, you can quickly expose the salient weaknesses in your design and/or assembly process.

The value of HALT is it’s quick and often finds problems not previously known. You will destroy one or more prototypes, yet the value of knowing specifically what needs improvement more than justifies the sacrifice of a few photos.

Conducting HALT may be part of your reliability plan. Keeping a few steps in mind will help make sure your HALT does provide value back to your development efforts. [Read more…]

Telematics Counting Data Analysis

In my prior article, an overview of vehicle telematics was provided. Telematics data includes time stamped records and fields containing count or parametric data recorded from the vehicle CAN bus. The count data is always a non-negative integer and the parametric data is stored as real numbers, generally in scientific format. This article focuses on the analysis of counting data.

Count data is used to monitor events, i.e., the number of trips, the days of operation, the calendar date, door open/close cycles, the number of engine starts/stops, or other variables. So, if a variable is selected for analysis, how can it be analyzed and a vehicle be characterized? How can fleets be analyzed? Can vehicle usage percentiles be determined?

Guest Post: Why Soft Skills Are the Hardest Skills to Acquire

A Guest Post by Kay Sandberg, Christopher Harding, and Will Wilkinson of Luminary Communications

Remember that first time you were asked to step into a leadership or management role, or to manage a client relationship? The experience was probably exciting and unsettling at the same time. Something different was asked of you.

While many of us have succeeded as individual contributors or team members, succeeding as a leader or manager requires a new set of skills we have often not been given the opportunity to acquire. This applies whether we carry an official leadership responsibility or not. In a future article it would be interesting to explore the distinction between “leader” and “manager”. [Read more…]

The 5 Fatal Mistakes of Customer Service

You would think that anyone who provides a product or service would understand the value of a satisfied customer.

Satisfied customers come back for more, they spread your name around with their friends and colleagues and talk about you in that bright eyed way a teenager talks about their first love. While it would be fantastic if this feeling of mutual admiration could last a lifetime, the reality is in the service and consulting business the average relationship between a customer and a client is somewhere between 5 and 7 years.

Leading & Lagging KPIs, What Is The Difference?

Using Leading & Lagging KPIs Can Make The Difference In Driving Performance, By Allowing You To See Into The Future.

This is the second part of a mini series on Key Performance Indicators. If you haven’t already please read the first post of this series on KPIs.

KPIs are often used to measure the past performance of a process, but did you know that they can be used to see into the future and predict the performance of the organization?

KPIs can be used to measure past performance, or predict future performance. This is because there is a cause and effect relationship between leading and lagging KPIs. When a process is measured, it will in turn effect another process which is also being measured, providing insight to future performance. [Read more…]

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

If Knowledge is Power, then understanding the cascading factors that shape our destiny can potentially offer Disruptive Knowledge and Decisive Power. Cascade Effect Thinking (CET) is a new paradigm that dynamically discovers the truth about interacting threats and opportunities in unique, analytical and gamified ways. [Read more…]

Magnetic Flow Meters

Mag-flow meters are used to measure the flow velocity of conductive liquids. In a magnetic flow meter an electromagnet placed either side of the bore creates a magnetic field when the power is turned on. As the conducting liquid flows through the magnetic field a voltage is developed across the liquid. Insulated electrodes flush mounted in the wall of the meter detect the voltage. The magnitude of the induced voltage is proportional to the liquid velocity, the length of the meter and the strength of the magnetic field.

Keywords: electric current, isolation flanges, calibration. [Read more…]
