Thuật ngữ Frequent Verification & Validation trong Agile là gì? Luyện thi PMI-ACP

Early and frequent testing both within and outside the development team to reduce the cost of quality (change or failure)

  • Validation(usually external) the assurance that a product, service, or system meets the needs of the customer
  • Verification(usually internal of team) the evaluation of whether or not a product, service, or system complies with a regulation, requirement, specification, or imposed condition

Agile measure to ensure frequent validation and verification:

  • Testers are included in the development team from the beginning taking part in user requirements collection
  • Unit testings are created for continuous feedback for quality improvement and assurance
  • Automated testing tools are used allowing quick and robust testing
  • Examples: peer reviews, periodical code-reviews, refactoring, unit tests, automatic and manual testing
  • Feedback for various stages: team (daily) -> product owner (during sprint) -> stakeholders (each sprint) -> customers (each release)
