by: Shawn P. Quigley & Jon M Quigley Measurements and Bias Solely by the process of observing something we can alter the thing which is being observed. This is a known as the observer-expectancy effect.  This effect is born out of conscience and subconscious biases of the observer.  In the case of observing people, we […]

Verification and Validation The definition for verification and validation can be found at[1]:   We must express some disagreement with the activities associated with the individual areas. For example, testing is not limited to Validation. Testing is also a function of verification as we will use these techniques to understand if the instantiation of the […]

Having the plan is only partially helpful.  The list of test cases and the expected rate of accomplishment allows us to refine our estimates as we progress through the testing.  We will be in a position to provide the project manager and stakeholders with a better “ETA” (Estimated Time of Arrival) just like the GPS […]

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 […]

We will continue our review of CMMI and requirements management practices.  As we have seen in the earlier posts, managing the requirements is necessary for efficient development and doing so has positive impacts on the project as well.  Specifically, the project benefits when the organization stands behind attaining the requirements, and is in for a […]

Continuous Deliver and Embedded Automotive I have worked on projects that employed continuous delivery for embedded products. The embedded product was an automotive component.  The core of the software (the operating system) was specified using conventional approach. This operating system consisted of the maximum model requirements for this globally used component. The component looked and […]

Project Closure and Team Disband One of my favorites and often poorly executed part of a project is the project closure.  Project closure is not just a simple wipe our hands together and smile, then proclaim that we are finished with the project. It is not even handing the customer our results and patting everybody […]

The Emissions Tango There is so much to learn from this case for those who develop products for a living and automotive products in particular.  Understanding the impact of concept selection and testing of the product on the project’s success and product quality is important.  The early decisions we make regarding the development of the […]
