Poke Yoke Jon M Quigley There are a set of tools and techniques that come with developing products for the automotive industry and are part of the Advanced Product Quality Planning for the product. We have written about APQP or some years and have decades of experience in this approach to product development. In general, […]
Missing Requirements Sometimes the best way to convey the challenges in product development, is to show some of the reasons things can go wrong. To that end I am going to regale you with a tale of requirements gone astray. Wearing Many Hats I worked at a small company a long time ago. I am […]
Why formalize root cause analysis? There are many approaches to determining the root of our problems. In the automotive world, there are two typical approaches, the 8D or the 8 Discipline, or the A3 (named for the paper size). We will not go into the details of either of these approaches but you can find […]
We have written much on requirements in other blog posts. We have been maintaining this blog for years, admittedly sometimes more fervently than others. We have created a schedule for our blog posts and other events by Value Transformation personnel available either on the event location on the website or as a downloadable from the […]

They do not care about the process. They do not care about the creative problem […]
Testing Complex and Embedded Systems What set of conditions could cause this event to occur? When we have elicited all we can from the customer about fault information, it is time to proceed further in our analysis. This next step requires investigation of the design to understand how the symptom of failure described could happen […]
Not all television is not mind numbing. I enjoy The History Channel and many other similar channels as these are not exactly learning opportunities but close. However, my son turned us on to a show called House on Netflix[1] and it is very interesting. House (also called House, M.D.) is an American television medical drama that […]
