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 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 […]

The initial product requirements provide the product baseline. Our project planning will be focused upon delivering meeting these requirements. In a phased development process, we will prioritize the requirements (shown earlier) and deliver iterations.  This staged delivery allows us to gain additional insight into the product.  We may learn things that necessitate changes to the […]

We now have linked our scope through to the various levels of requirements. We are then able to prioritize the delivery of the various project obligations.  The prioritization may be based, for example upon: Technical need Customer need Regulatory requirements Complexity and Risk Technical needs are the dependencies to getting the product features working, for […]

Our configuration management is borne out of our requirements.  In our earlier blog post, we discussed how the project scope must be traceable to the requirements. In the case we present below, the project scope is a particular function or need to be met, for example a new feature or function for an automobile.  We […]

Requirements are fundamental to project success as the scope definition.  Additionally, there are dependencies that impact the ability to produce suitable requirements.  A few of those things are: Well defined scope of the work Sponsor and customer involvement Capability of the requirements authors Prioritized functions or abilities The needs or objectives of the customers or […]
