Requirements Verification and Validation

Correct Answer: Creating and testing performance-based prototypes

Creating and testing performance-based prototypes is the most effective technique to address stakeholder concerns about system performance. Here's why: Prototypes provide tangible evidence and measurable results that can validate or refute performance concerns. They allow stakeholders to: - Observe actual system behavior under various conditions - Measure real performance metrics - Identify potential bottlenecks early - Make data-driven decisions based on actual results Why other options are less effective: Documentation reviews are too theoretical and cannot provide concrete performance data. Acceptance criteria matrices are useful but are still theoretical documents that don't demonstrate actual performance. Competitive analysis benchmarks, while valuable for setting targets, don't address the specific performance concerns of the proposed system architecture and implementation. Prototyping is especially valuable because it provides empirical evidence of performance capabilities, helping stakeholders make informed decisions based on actual results rather than theoretical documentation or comparative analysis.

Correct Answer: Peer reviews with structured checklists

Peer reviews with structured checklists is the most effective technique for requirements verification on large-scale projects because: Strengths of peer reviews with structured checklists: - Combines human expertise with systematic methodology - Provides consistent evaluation criteria across the project - Helps catch errors and inconsistencies early - Scales well for large projects while maintaining quality - Promotes knowledge sharing and team alignment Why other approaches are less effective: Random sampling with automated tools risks missing critical requirements and may not catch context-specific issues that human reviewers would notice. Parallel verification by multiple teams can lead to redundant effort, inconsistent interpretations, and coordination challenges that slow down the process. Sequential review cycles with progressive sign-offs can create bottlenecks and delay the verification process, especially in large projects where stakeholder availability may be limited. The structured checklist approach provides the optimal balance between thoroughness and efficiency, while ensuring consistency and maintaining high quality standards in the verification process.

Correct Answer: Create user-friendly visual models and conduct structured walkthroughs

Creating user-friendly visual models and conducting structured walkthroughs is the most effective approach when end users have difficulty understanding technical specifications. This solution is best because: - Visual models help translate complex technical concepts into easily understandable formats - Structured walkthroughs allow for interactive discussion and clarification - It promotes active engagement and better comprehension - It enables immediate feedback and validation from users Why other approaches are less effective: Developing comprehensive technical documentation would add more complexity and technical details, making it harder for users to understand. Scheduling additional technical training sessions would be time-consuming and might overwhelm users with technical information they don't need for their daily work. Having IT specialists explain technical requirements would likely result in more technical jargon and complexity, rather than making it easier for users to understand.
