Requirements Engineering

Requirements Engineering (RE) is a systematic discipline for eliciting, analyzing, specifying, validating, and managing requirements for systems and software. Its origins lie in addressing project failures caused by incomplete or ambiguous requirements. The international standard ISO/IEC/IEEE 29148 provides a comprehensive framework for RE processes. In the context of risk management, particularly for privacy, RE is the critical bridge between abstract legal obligations and concrete technical implementations. For instance, it translates principles like GDPR's Article 25, "Data Protection by Design and by Default," into specific architectural constraints and functional requirements. By formalizing this process, RE proactively mitigates compliance risks, prevents costly rework, and ensures that security and privacy controls are embedded into the system from the outset, rather than being added as an afterthought. It is a foundational practice for building trustworthy and compliant systems.

In enterprise risk management, RE is applied to systematically translate regulatory and security policies into verifiable system requirements. The process typically involves three key steps. First, **Regulatory Requirement Elicitation**, where cross-functional teams (legal, compliance, IT) deconstruct laws like GDPR or CCPA into actionable requirements (e.g., mapping the "right to erasure" to specific data deletion functions). Second, **Risk-based Analysis and Specification**, where techniques like threat modeling or Data Flow Diagrams are used to identify high-risk data processing activities. Based on this analysis, specific Privacy Enhancing Technologies (PETs) are specified as non-functional requirements, guided by frameworks like ISO/IEC 29100. Third, **Validation and Traceability**, where a Requirements Traceability Matrix (RTM) is created to link each legal clause to design documents, code, and test cases. This ensures complete coverage and provides auditable evidence of compliance. A global financial firm, for example, used this approach to reduce its audit preparation time by 40% and achieve a 98% pass rate on its privacy compliance assessments.

Taiwan enterprises often face three primary challenges when implementing RE for compliance. First, a **Siloed Knowledge Gap** exists between legal/compliance teams who understand regulations and IT teams who build systems, making accurate translation of legal prose into technical specifications difficult. Second, the prevalence of **Agile Development Methodologies** can create a cultural resistance to the perceived "heavy" upfront work of formal RE, leading teams to overlook critical non-functional requirements like privacy. Third, **Resource Constraints**, particularly in small and medium-sized enterprises (SMEs), mean a lack of dedicated business analysts and specialized RE tools, resulting in ad-hoc requirements management via spreadsheets. To overcome these, enterprises should establish cross-functional "compliance squads," integrate lightweight RE practices into Agile sprints (e.g., defining "Definition of Done" to include privacy checks), and leverage existing collaboration tools like Jira with plugins for traceability before investing in expensive platforms. The priority is to build a shared understanding and a basic traceability framework.
