We submit that a Failure Mode and Effects Analysis (FMEA) review is a form of design review. After all, one of the purposes of a design review is to try and remove defects before they appear in the product and that is the entire rationale for the FMEA in the first place. Yet, most of […]
A modular FMEA is a modification of the standard Failure Mode and Effects Analysis tool into meaningful components. For example, we can select “stepper motor” as a component of a typical instrument cluster used in the dashboards of truck and autos. We would then create our FMEA to deal with all issues related specifically the […]
Many organizations have a series of activities or processes (design reviews, analyses, verifications, validations, etc.) that they go through to produce the end product or service. The work will start with some kind of development process, which may be a matter of days, months or years, depending on the complexity of the product or service. […]
We have hardly seen instances of this issue being discussed. We are painfully aware of the large extent we often require of configuration management because we have to work with tools in the embedded environment called “cross-compilers.” These tools allow the developer to work in a familiar programming language such as C and then produce […]
We have discussed some issues regarding configuration management already and we will continue to discuss this underlying topic in this blog—it is that important! Mass customization presents specific issues. Mass customization occurs when set up our systems such that customers have the ability to request substantial modifications. Mass customization works when we take some sensible […]
We take a time out from the configuration management discussion. We see in the news numerous companies with field quality problems and we cannot help but think of the discussions we have had with colleagues about how many organizations handle their product testing. Testing, done right, is a lead indicator of product quality. It is […]
We have seen situations where poor configuration management has led to embarrassing situations with customers. In one case, a supplier shipped parts to a relatively new customer in which neither the hardware revision nor the software version were known. The parts arrived at the customer location for demonstration by a senior sales manager–none of them […]
by Jon M Quigley Simulation activities can help evoke the requirements for a product without actually having to build the product first to learn something. Simulation need not be highly technical, though it can be. I have seen simulation of screens for an instrument cluster human machine interface (HMI) that made use of excel links […]
Beware the “I know, I know” syndrome from an enthusiastic employee. The event occurs when the employee remembers a similar incident with a returned part, production line failure, or software issue. Unfortunately, reasoning from effects to causes is actually a logical fallacy called “affirming the consequent.” We cannot assume that a given effect has but […]
One of the most important concepts we have seen in any environment where we need to get things done is the POWER OF THE ROUTINE TASK. Basically, we make any work that needs to be accomplished part of a routine, say, in the morning, when we begin our workaday activities. Some of these tasks are […]
