Join Terri Wagner for an in-depth discussion in this video Verifying the requirements task list, part of Project Management Foundations: Requirements.
- Verification and validation of your requirements are critical to a successful product, service, or result being turned over to your internal or external customer. In verification, you confirm that you've built the system right. In other words, you'll confirm that the solution meets all the written specifications. In validation, you confirm that you've built the right system. In other words, you'll confirm that the solution works as it's supposed to, conforms to the use case scenarios, and meets the customer's needs.
Typically, validating your project requirements takes place across the project life cycle, and is accomplished by presenting requirements for review and approval, and managing conflicts or issues with the requirements. When verifying requirements, you'll be quality checking the analyzed requirements to ensure that they're correctly defined, ready for formal review and validation by your customers, checked against the documented specifications, and are complete and correct.
Other characteristics that may be reviewed are cohesiveness, or whether all requirements support the overall purpose, scope, and feasibility. With feasibility, you're verifying that each one can be implemented within the existing infrastructure, based on the timeline, budget, and resources you have for your project. When validating requirements, you'll be ensuring they deliver value to the business, fulfill business goals and objectives, meet stakeholder needs, and align with stakeholder, solution, or transition requirements to the business requirements.
Steps involved in validation include identifying assumptions, defining measurable evaluation criteria, determining business value, determining dependencies for business realization, and evaluating alignment with your business case and the opportunity cost. Remember, a key element of the verification technique is to ensure that your project team can prove the written requirement has been met by devising a set of tests, checks, or measures, so the client is confident that what they requested has been delivered.
