The customer is the receiver of the output; the customer can be an internal end customer or an intermediary to the next “chain” of events on the way to the final customer. Ultimately, we are aligning our actions (Suppliers, Inputs, Processes, and Outputs) in a way that provides the biggest benefits for our final customer. […]

To perform embedded software testing, we recommend five phases of testing. These phases may take place concurrently and are as follows: Compliance testing Combinatorial testing Stochastic (or exploratory) testing Extreme testing Attack mode Each of these methods provides some view of the product the other method does not. Of course, testing the product is not […]

Requirements management and configuration management are required for anything that even closely resembles effective testing.  Experience suggests failing in these two areas unnecessarily complicates the product verification activities, and we will show some of those traumas in the next few posts.  An iterative and incremental product development process calls for reviews throughout the development process.  […]

In some recent discussions with product development neophytes, we have heard a merging of the concepts of verification and validation.  Let us set the record straight.  Verification and Validation are not synonymous.  The World English Dictionary defines verification as “establishment of the correctness of a theory, fact, etc…”   and validation as “to confirm or corroborate”.  […]

We have witnessed a disconcerting trend.  That trend is in consolidating risk reserves for projects into one, centrally managed bucket of money.  This bucket was once reserved for the unknown-unknowns and was called a Management Reserve.   However, more businesses are beginning to strip projects of their known-unknown Project Risk Reserves and placing calculated project contributions […]

We have recently had a discussion on what it takes to quality assure software. The discussion focused on FMEA and the role it plays in quality assurance.  The discussion began to sound as if the FMEA was the panacea for poor quality. There is no silver bullet. To be sure the FMEA (which is essentially […]

We have our requirements, our iterative packages and content defined, and now the developers are producing the iterations. During this time, the verification and test folks have been creating the test cases or details on how we intend to confirm the product performance. Our requirements provide the fodder for our testing.  For each requirement there […]

Once we have our captured our requirements. We identify the substance of the content for the iterations from the development.  In fact, recall from the requirements prioritization blog post. That work has given us some insight into how the iterative packages could be developed and what content or capabilities are to be delivered.  In the […]

One under or ineffectively used tool is the specification or requirements review, which is a form of design review. In this case we are reviewing the design while it is still easy and cheap to make adjustments.  Experience suggests, if we do not just forget to do this activity, it is a hastily arranged activity […]

You need not been so technically skilled to be able to see how many project fail due to requirements.  We provide a brief list of the failings below: Requirements control Insufficient time Did not include the sponsor or customer Late delivery of requirements Requirements traceability We will not write any more on requirements control that […]
