How can you align the verification and validation process with the needs of space system stakeholders?

1 Define the V&V scope

The first step is to define the scope of the V&V process, which includes identifying the stakeholders, their needs, and their roles in the process. Stakeholders can be internal or external to the project, such as customers, users, sponsors, regulators, suppliers, or developers. Their needs can be functional, performance, safety, reliability, or usability related. Their roles can be as reviewers, approvers, testers, or observers. By defining the scope, you can establish the objectives, criteria, methods, and resources for the V&V process.

3 Apply a systems approach

The third step is to apply a systems approach to the V&V process, which means considering the system as a whole and its interactions with its environment. A systems approach can help you identify and address the interdependencies, interfaces, risks, and uncertainties of the system. It can also help you balance the trade-offs between the system performance, cost, schedule, and quality. You can use systems engineering tools and methods to support the systems approach, such as system models, architectures, analyses, or simulations.

4 Tailor the V&V methods

The fourth step is to tailor the V&V methods to suit the characteristics and needs of the system and the stakeholders. V&V methods can be analytical or empirical, formal or informal, qualitative or quantitative, or combinations of these. You should select and adapt the methods based on the system complexity, maturity, criticality, and novelty. You should also consider the stakeholder expectations, preferences, and constraints. Some examples of V&V methods are testing, inspection, analysis, simulation, demonstration, or verification by similarity or analogy.

5 Document and communicate the V&V results

The final step is to document and communicate the V&V results to the stakeholders. The results should provide evidence that the system meets the requirements and satisfies the stakeholder needs. The results should also highlight any deviations, discrepancies, or defects that need to be resolved or accepted. You should use clear, concise, and consistent formats and language to present the results, such as reports, matrices, checklists, or dashboards. You should also use appropriate channels and media to communicate the results, such as meetings, emails, webinars, or videos.
