We know that a very simple product or system can generate a vast number of potential test cases. With more complex systems, this number becomes astronomical. This is the result of a factorial calculation! One technique we use to get around this problem originates with designed experiments. Many designed experiments are based on orthogonal […]
We have never seen a meaningful employee evaluation system. The abominations are generally designed as a tool to assess the performance of the employee with respect to corporate goals. When they present the illusion of quantification, the values are really qualitative and they will inflate over time as people are ‘soft’ about providing ‘real’ assessment. […]
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 […]
Risks need to be assessed in regard to their business impacts, so that business decisions can be made promptly. Strategies should be built and decided based on the quantitative value of the risk. Managers must decide on whether to spend $500,000 to avoid a delay in a project. How long that delay is impacts the […]
Are you tired of training that is mostly blather from the speaker/teacher/trainer? We use techniques that eliminate this issue. For example, we are fond of “training games” that allow our clients to get some person-to-person and hands on activity. We also ask you to work examples of the kind of material we are training on; […]
