Not a Verification Problem I recently had a flash of a project from the past. The project had a fixed delivery date.  The project was to deliver a system through iterative and incremental deliveries. Sounds pretty good right? An iterative and incremental delivery of sub systems and components to the verification group in a way […]

Below is an excerpt of our book Testing of Complex and Embedded Systems Pries, K., & Quigley, J. (2011). Chapter 4. In Testing Complex and Embedded Systems (pp. 33-35). Boca Raton, FL: CRC Press.   Basic Principle of Testing The verification and test group is there to provide some critical and unbiased review of the […]

Qualitative Testing Qualitative tests look for a change in a quality; for example, a color might change. Qualitative tests always involve the use of attributes rather than variables values (e.g., temperature). Consider the Kastle-Meyer test for the presence of blood–an archetype for qualitative forensic testing. The test is impressively quick and functions as a decision […]

Manufacturing Project The project whose scope includes delivery through manufacturing will include some quality assurance steps from the previous blog post to ensure we are able to produce the designed product to the quality expected by the sponsor. Trial Production Run and Problem Discovery The manufacturing team reviews the development of the manufacturing line with […]

In our last blog post, we referred to the APQP  (Advanced Product Quality Planning) activity of DFMEA.  The post was about the attempt to perform late in a project.  The point to the DFMEA in that instance was lost; at best, if we found a serious problem, would be to abort the launch.  The post […]

Quality Project Deliveries No matter the expected delivery, objective or product from the project, to deliver a high quality outcome is the result of intention.  It comes from the understanding of the scope, the planning and execution of appropriate quality securing actions and consistent monitoring and adjustment to lessons learned along the way Quality and […]

Many thought the language “breaking”, as did many others, to be unclear or ambiguous. The language in this discussion originates from the […]

Agile Verification Blog Recollection In our past blog posts we discussed a conventionally executed (staged gate) project with constituent parts (the verification) being executed using agile techniques. We realized we missed some pertinent information in our series post of agile verification in a conventional project. Agile Verification Prediction We talked about the burn up chart based […]
