Creating a separate software test group has pluses and minuses. At a minimum, we may have more to manage. Some of the minuses are a product of human nature. When we know our work will be inspected, we will often assume the inspector will catch issues and we pay less attention to the issue ourselves. […]
The Pareto chart (not to be directly confused with the Pareto probability distribution function) is a simple approach to revealing significance in data. Before we plot our chart, we need to complete some initial work: Gather the data in a natural format (count, floating point [decimal], dollars, etc.) Sort the data from high to low […]
We have been on a bit a tear (or rant) about FMEAs. We suggest the FMEA documentation is part of the core of a design process. The ultimate approach we have seen is that of Michael Anleitner (The Power of Deduction: Failure Modes and Effects Analysis for Design, Quality Press, 2010), which uses functional analysis […]
There is only one way to describe this scenario and that is via a story. Consider the organization that is coming to the end of the project. The product is a complicated subassembly that goes into a larger system and has numerous interactions and incarnations of the design. They are late in the delivery of […]
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 […]
We addressed the issue of the modular FMEA in a previous blog. We also suggest that the FMEA in its various guises is also a great place to capture lessons learned. In the medical, aerospace, automotive, and food industries, some kind of FMEA is a required document. Since we already must create these documents, why […]
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 […]
We have heard executive complain when an employee they put through external training left the company to pursue a better-paying job somewhere else. Our question has always been “Why didn’t you take care of your investment?” Training employees is an investment of time and money in much the same way as tilling and seeding the […]
Brainstorming as neologism began with Alex Osborn of the advertising agency BBDO in 1942. His primary concern was creative thinking. In general, classical brainstorming generally follows this pattern: Gather a group of people Decide on a duration and quantity of ideas desired Solicit ideas from group members No editing, snide comments, or insults Collect ideas […]
Over the years, we have heard executive level individuals cry out for cultural change in their organizations without understanding the ramifications of what they are saying. With cultural transformation as usually touted, we are talking about massive levels of upheaval. The upheaval approach can be counterproductive if it does little more than produce a culture […]
