What do you think verification is?

Verification is the process of checking a product against specified specifications and requirements before its release.

Key aspects of verification:

• "Are we building the product correctly?" - focus on the process of creating the product, its architecture, code, documentation.
• Checking compliance with design documents, technical specifications, coding standards, and other internal standards.
• Conducted at early stages of the software development life cycle (SDLC).
• May include static code analysis, documentation review, database structure verification.

Examples of verification activities:

• Review of requirements and specifications for completeness, consistency, and clarity.
• Analysis of architecture for compliance with declared goals and design principles.
• Checking source code using static analyzers.
• Review of test plans and test cases.

The key difference from validation: verification focuses on internal consistency and correctness of construction, whereas validation is on external conformity to user expectations and suitability for use.
