In preparation for our trip to Eindhoven University of Technology to lecture on Configuration Management, we provide a brief excerpt on the evolution of the horseless cariage. Traditionally new market segments open due to the need to solve a problem. Such problems may be real as in the case of the environmental crisis solved by […]

It is clear to me that some people think an agile approach means you can willy-nilly delete things in the process. This is also true for conventional project, but I do not think for the same reasons. For conventional projects, it seems time pressures cause elimination of certain functions or processes to keep the schedule. […]

We see some company responses to economic downturn are to eliminate staff as if that were the only way to become a viable company once again. We wonder if these companies have some cost improvement methodology behind them that would give their management other options than summarily removal of personnel.

We have mapped how long it takes to prepare the vehicle for testing using the histogram. We have used the Ishikawa diagram to generate ideas we wish to investigate as causing the time to be longer than we would like it to be. Our next step is to see if the ideas suggested in the […]

We like the title Random Acts of Product Development.   It often appears that product development is a collection of ill-conceived and poorly executed tasks.  Those planning refuse to recognize dependencies between groups and tasks and are unable or unwilling to acknowledge they are really working within a system – blinded by the solely important launch […]

            Extreme testing occurs when we deliberately “torture” both the hardware and software to see what happens under undesirable conditions. Some examples of extreme testing include: Random voltages within the allowable voltage boundaries Voltage slews Deliberately introduced random noise on the data bus Extremely high bus loading (over 80% and sometimes over 90%) to see […]

            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 […]
