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
• SG 1 Prepare for Validation
– SP 1.1 Select Products for Validation– SP 1.2 Establish the Validation Environment– SP 1.3 Establish Validation Procedures and Criteria
• SG 2 Validate Product or Product Components
– SP 2.1 Perform Validation– SP 2.2 Analyze Validation Results
Generic Goal and Practices Summary
• GG 2 Institutionalize a Managed Process
– GP 2.1 Establish an Organizational Policy– GP 2.2 Plan the Process– GP 2.3 Provide Resources– GP 2.4 Assign Responsibility– GP 2.5 Train People– GP 2.6 Manage Configurations– GP 2.7 Identify and Involve Relevant Stakeholders– GP 2.8 Monitor and Control the Process– GP 2.9 Objectively Evaluate Adherence– GP 2.10 Review Status with Higher Level Management
• GG 3 Institutionalize a Defined Process
– GP 3.1 Establish a Defined Process– GP 3.2 Collect Improvement Information
