Test and Verification Management
Test and verification management are the processes and procedures to suitable critique the product (hardware or software) or processes (production). This is risk identification and mitigation activity as it attempts to quantify quality attributes of the product that may cause concerns with the customer during application. Testing and verification is also part of project management in that the results are often used to confirm contractual obligations are met, and thereby are part of project closure. Testing and verification management contain, planning and control, analysis and design, execution, reporting and closing activities. Hardware testing may include environmental stimuli (multiple simultaneous such as thermal and vibration) as well as testing the product to the extremes of functionality.
In testing closure the objective and specific deliverable items from the testing are compared to the actual achievements and deliverables. The testing documentation is stored in a way that is easily retrievable along with the information on the product iteration the specific test cases were conducted. The test environment configurations are archived so these can also be retrieved at a later date should that be needed. Lessons learned are recorded from which the team will apply at some future date.
During test execution the tests are conducted on the product. Each of the test conditions and test environments are used to conduct the defined tests. Sometimes there will be spontaneous testing conducted, that is not one that was born out of the scope, plan or test analysis, but from what is learned in the process of conducting the test. Test execution will also be responsible for re-testing as perhaps the results of the test were some anomaly based upon the test configuration, or to learn more about the failure to be able to accurately report the details of the conditions that caused the failure. These are clues the developers will use to find the reason for the failure (hardware or software). Test execution address regression testing, that is testing of old parts of the product that have not changed, but require testing since the product has changes – this is largely associated with software.
Test Exit, Metrics and Reporting
Testing produces data from which an informed decision about the product can be made. These metrics will inform the team and other stakeholders the product’s suitability for release or production. Test metrics such as failure rates and severity remove some of the uncertainty from the launch. This phase of the testing produces reports where this information will reside allowing the project manager, stakeholders and executives to decide whether to launch or not based upon the results.
Test Planning and Control
To be able to test requires an understanding of the objectives of the project and customers. This understanding makes it possible to discern specific risks and clarify the scope of the testing to make assessment of those risks possible. Test planning will uncover and define the best test strategy along with discovering the talent and equipment required. Additionally, the planning will evoke key metrics or measurements from which the testing and results will be evaluated.
Test Analyze and Design
In test analysis and design, specific test conditions are identified from which the details of the testing will be created. This will require inputs such as product requirements and drawings, specifications, system descriptions and interfaces to other components and typical and extreme applications of the product. This will generate specific test methods, criterion, and metrics that will lead to detailed test cases along with the input data (test conditions) for the test. There is a strong connection between the product requirements and design documentation and the test details.
Test and verification management – techniques for ensuring the product design, material and, where applicable, manufacturing processes culminate in meeting the customer’s needs. At the minimum verification serves to confirm or refute the product meets requirements. However, there are many other approaches to testing iterations of the product through the development process. This includes software testing, which consists of processes and techniques that is coupled with the development effort to ensure the product quality over prototype iterations and the full lifecycle of the product.

The use of decision matrix tools can help us make a better decisions for our project and our organization and improve the outcome of our work.
Projects are People
People are Human I realize this piece is likely, nearly certainly, to ruffle some feathers. That is not my intention for sure. We have written on the impediments to us seeing things truly as it is. There are many cognitive biases that may plague us. In fact, we dedicated an entire section in our latest […]
Once Upon a Time
Once Upon a Time I worked while I was acquiring my undergraduate engineering degree, hell, I worked while getting all three of my degrees. My undergraduate was especially interesting, in that I did not have a mass of skills so my work was not a high-paying gig. I am grateful for the job, but there […]
Sergeant York – and Old Homesteads
Sergeant York – and Old Homesteads Gatlinburg Area Recently, over the Memorial Holiday, Sergeant York, well, more like rewatched it. I recall it from when I was a kid on the old movies channel. Not when it first hit the big (or little) screen mind you. However, I have since then had some experiences that […]
Manufacturing X0 Event
It was a wonderful learning event at the Manufacturing X.0 Southeast event. I want to thank Lacy Ashton and Boni Quatroche for making the even and my involvement possible. There was much to learn from the confluence of topics from AI to Big Data, from the individual to team learning and retrieval. All of these […]
Failure: The Option
Failure: The Option Media I was once in an engineering team meeting, where the snippet from the movie Apollo 13 was played. The scene demonstrated that famous saying, failure is not an option. I have heard this many times since then, not in business, but on other television shows and competitive events. The thing is, […]
Risk Management from Front and to Back
Risk Management from Front and Back Recently I spoke at a Metrolina PMI Chapter on Risk Management. If we have been managing projects, we know that risk management is significant to ensuring project success. Risk management starts from the very beginning of the project, the scope, and our strategy selection will all impact the risks […]
To Learn, or Not to Learn- There is Really No Question.
To Learn, or Not to Learn- There is Really No Question. I have spent time in a variety of roles in product development, from engineer to manager and process manager. In the latter, as project and process manager, even in early 2000, there were organization processes and structures in place to encourage and record learning […]
My How We Change.
How we change. I shared this with those that I usually have to review my writing. They said I should not share this as it seemed very personal. They said it seemed like it was something somebody would not share. After a short rumination, I decided to share this, writing. It amazes me where I […]
The LinkedIn Elephant
The Organization Organizations, or most successful organizations, are not static. To remain an ongoing concern the organization will need to adapt to identified opportunities. This will require growing the talent base, either organically, that is from within, or by finding talent external to the organization. From an external perspective, how do we know the right […]
Career Change Recently we had a question come to us about how a person transition from one industry or a specific job title to another industry or another area of the company that requires different skills from what we presently have. Perhaps as a way to avoid becoming stale, we may want to explore […]
