by: Shawn P. Quigley Whereas we have discussed some of the possible flaws in measurements we can all still agree that they are needed to provide both improvement in processes and the organization. However, other aspects of obtaining data for the production of quantifiable information: trend analysis and process evaluation, is the human factor both […]

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 […]

In the development phase of the product development life cycle, we are generating ideas for the product. We see opportunities in the market place and wish to explore if we can capitalize (not a vulgar word) upon these opportunities.  Perhaps a new technology has become available to us.  Our organization will want to investigate the […]

by Rick Edwards and Shawn P. Quigley How projects and processes are related If one were to describe their project to someone, they would most likely describe the end deliverable or objective of the project (a.k.a scope), the expected completion date (time) and the expected resource requirements needed to faithfully execute the plan (cost).   Nowhere […]

By Shawn P. Quigley More on Maslow In our previous discussions we have referred to Maslow’s Theory of Human Motivation (Hierarchy of Needs) and how this relates to work place motivation. To best continue our discussion we must first review some of the tenets of Maslow’s theory in more detail and dispel the misconception that […]
