Testing: closing the loop through verification and validation of procedures

The testing phase in an integrated procedures system for nuclear power plants is described. Testing through verification ensures technical accuracy and written correctness. Procedures are verified first by writers, and then by qualified reviewers through the review and approval process built into the integrated procedures system. Testing through validation ensures usability and operational correctness. Specialists independent of the procedure writer validate procedures using one or more methods: simulator, mock-up, walk-through, table-top, actual use, or reference. Testing of the whole procedures system is provided by feedback from a requirements database, periodic assessments of management programs, trainers, and users
