Poor Excuse for Not Automating Testing Recently I came across and participated in a social media exchange that proposed that automating product testing (software) was not helpful.  Their assertion was backed with comments about personnel new to testing who cannot learn how to test. Testing and System Complexity System and software complexity, the number of […]

We have recently posted how assumptions, left unquestioned can damage a project. It is similarly true for the product when we use models and simulation to generate our product.  In the course of building these models, we will know some things for certain.  Some attributes of the model we may think we know for certain […]

By Jon M Quigley We have discussed the Failure Mode Effects technique a few times in the past.  Though Failure Mode Effects and analysis seems to be a powerful tool, the problem is you do not know if the FMEA is effective and perhaps you will never know.  The Failure Mode Effects Analysis tool, theoretically, allows […]

Business Imperative There was a discussion going on LinkedIn and Twitter about technical debt, and management decisions. Sometimes business imperative trumps technical debt, but you must acknowledge the technical debt, and compare the business positives against the technical debt negatives. Technical Debt We should probably start by giving a definition of technical debt.  Technical debt […]

Register for the free introduction to product (hardware and software) testing in a course online that covers the topics: Stakeholders / Sponsors Project Scope Configuration Management Static Testing Techniques (inspections) Dynamic techniques Approaches to testing Regression , Re-test and Human Interactions Evaluation Putting it together with TIEMPO Test Management This course includes the creation of […]

We have created an online introduction to product testing course. The course is free, and highly interactive. It consists of ten modules on topics listed below with some of the attributes per module.       1.)  Stakeholders and Sponsors   2.) Scope and Requirements   3.) Configuration Management and Testing   4.)  Static Testing Techniques   5.)  Dynamic Testing […]

Testing and Repeat-ability  Repeat-ability of testing results is important to establishing cause and corrective actions. If it is not possible to repeat the sequence of events leading to a failure, it is not possible to replicate and therefore difficult solve the cause of the fault or failure.  The steps that evoked the problem are necessary […]

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 […]

Why Lessons Learned are vital to the long-term vitality of organizations To best discuss any topic, we must first establish a common foundation from which to build. Let’s start by defining some key terms: 1. Lesson: an activity that is done in order to learn something; also: something is taught, a single class or part […]

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 […]
