Requirements Planning and Management

Correct Answer: Impact analysis matrix with stakeholder review sessions

Impact analysis matrix with stakeholder review sessions is the best technique for addressing cross-functional dependencies between requirements for several reasons: 1. It provides a structured framework to visualize and analyze relationships between requirements across different functional areas. 2. The collaborative nature of stakeholder review sessions enables real-time identification and resolution of dependencies. 3. It combines both analytical tools and human expertise to ensure comprehensive dependency assessment. Why other options are less effective: Comprehensive requirement documentation with cross-references can become too complex and static, making it difficult to maintain and update as dependencies change. Sequential review process with individual sign-offs limits the ability to identify cross-functional impacts since stakeholders review requirements in isolation. Automated requirement management tools, while helpful, may miss nuanced dependencies that require human judgment and cross-functional expertise to identify and analyze properly.

Correct Answer: Early defect detection through structured reviews

Early defect detection through structured reviews is the most effective consideration in requirements verification and validation planning for minimizing rework and reducing project costs. This approach is optimal because: - It catches issues at the earliest possible stage when they are least expensive to fix - Structured reviews provide a systematic way to identify and address requirement defects - Early detection prevents defects from propagating through later project phases - It reduces the cost multiplier effect of fixing issues in later stages The other options are less effective because: - Comprehensive documentation, while important, doesn't actively prevent defects and can be resource-intensive - Parallel validation activities can be complex to manage and may not effectively catch early-stage issues - Integration of automated tools and manual methods is valuable but comes later in the process and doesn't focus on early detection

Correct Answer: They help visualize requirements and enable early feedback on functionality

Prototypes play a crucial role in requirements verification and validation planning by providing tangible demonstrations of proposed functionality. The correct answer reflects that prototypes help stakeholders visualize requirements and gather early feedback, which is essential for requirements validation. This enables teams to identify misunderstandings, gaps, or issues early in the development process. The other options are incorrect because: Prototypes are supplemental tools that enhance requirements documentation and testing - they do not replace formal documentation processes. While prototypes can help identify some technical challenges, they do not provide comprehensive analysis of all potential issues and security risks. This would require dedicated security assessments and technical analysis. Prototypes facilitate better understanding between stakeholders but cannot guarantee perfect alignment between business needs and final outcomes. Perfect alignment is rarely achievable due to various factors including changing business conditions and requirements.
