In the world of system engineering, defining requirements is a critical step that sets the foundation for a successful project. However, determining which requirements warrant rigorous management and how to prioritize them can be a complex challenge. In this article, we delve into the question of which requirements should undergo meticulous scrutiny and explore the concept of a risk-based approach to requirements management. By adopting this approach, we can optimize our efforts, ensure compliance, and enhance overall project outcomes.

Exploring Requirement Complexity
To shed light on the issue, let’s consider an example. Imagine a project with two requirements: one specifying adherence to a particular electrical installation standard and another related to the color of switchboards. While the latter is a straightforward and easily verifiable requirement, the former encompasses a vast number of atomic requirements nested within multiple referenced standards. This raises the question: Should all requirements be treated equally during the management process?
The Traceable Hierarchy
To overcome the complexity, it is essential to establish a traceable hierarchy that links all requirements to the project’s objectives. By doing so, we can identify the critical requirements that directly impact safety and performance. This traceability ensures that every requirement has a purpose and contributes to the overall project goals. Moreover, it helps streamline the management process by prioritizing verification efforts based on the importance of each requirement.
The Role of Risk Management
Integrating the requirements management (RM) process with the project’s risk management (RM) process is another key consideration. By identifying and analyzing potential risks that may hinder objective achievement, we can align our verification efforts accordingly. By focusing on the requirements associated with the highest risks, we can address critical areas early on and mitigate potential setbacks. This risk-based approach empowers project teams to be proactive, agile, and in control of the project’s most significant risks.
Benefits of a Risk-Based Approach
Applying a risk-based approach to requirement specification offers numerous advantages. Firstly, it enables more concise and focused requirement specifications, making the entire process more manageable. Additionally, the traceability between requirements and risks ensures that compliance and safety concerns are prioritized. Furthermore, it promotes a more efficient allocation of resources, as efforts are concentrated on the requirements that truly matter.
Contractual Considerations
While a risk-based approach brings significant benefits, it is crucial to acknowledge that contractual obligations and project-specific contexts may influence the flexibility of this approach. Depending on the project’s contractual framework, some requirements may necessitate strict adherence and comprehensive management. Therefore, it is essential to strike a balance between contractual obligations and the practicality of a risk-based approach.
Embracing the Debate
The question posed at the beginning of this article sparks an important debate within the system engineering community. By openly discussing and exploring alternative approaches to requirement management, we can challenge traditional practices and foster innovation. It is through such debates that industry best practices evolve, and projects can benefit from improved efficiency, compliance, and overall success.
Conclusion
Defining requirements in system engineering is a pivotal step that demands careful consideration. By establishing a traceable hierarchy and incorporating risk-based thinking into the requirements management process, project teams can optimize their efforts, enhance compliance, and prioritize critical areas. While the debate surrounding which requirements warrant rigorous management continues, it is vital to embrace this discussion to drive progress and ensure maximum project success.
