Validation

• Judgments may need to be made about whether the value of the results will be commensurate with the resources devoted to doing the work.

• Verification is a Quality Control process that is used to evaluate whether or not a product, service, or system complies with regulations, specifications, or conditions imposed at the start of a development phase. Verification can be in development, scale-up, or production. This is often an internal process.

• Validation is Quality assurance process of establishing evidence that provides a high degree of assurance that a product, service, or system accomplishes its intended requirements. This often involves acceptance of fitness for purpose with end users and other product stakeholders.

Purpose of VER &VAL• The purpose of Verification (VER) is to ensure that selected work

products meet their specified requirements.

• The purpose of Validation (VAL) is to demonstrate that a product or product component fulfills its intended use when placed in its intended environment.

• verification: “are we building the product right”

• validation: “are we building the right product”

VERIFICATIONSpecific Goal and Practice Summary

• SG 1 Prepare for Verification

– SP 1.1 Select Work Products for Verification– SP 1.2 Establish the Verification Environment– SP 1.3 Establish Verification Procedures and Criteria

• SG 2 Perform Peer Reviews

– SP 2.1 Prepare for Peer Reviews– SP 2.2 Conduct Peer Reviews– SP 2.3 Analyze Peer Review Data

• SG 3 Verify Selected Work Products

– SP 3.1 Perform Verification– SP 3.2 Analyze Verification Results

Verificationan incremental process

• verification of – the requirements

• verification of – the evolving work products

• verification of – the completed product

• Verification for systems engineering typically includes prototyping, modeling, and simulation to verify adequacy of system design (and allocation).

PEER REVIEW

• The focus of the peer review should be on the work product in review, not on the person who produced it.

• These reviews are structured and are not management reviews

• Record data related to the preparation, conduct, and results of the peer reviews.

VALIDATIONSpecific Goal and Practice Summary
