REQUIREMENTS ENGINEERING

Requirements Engineering: Specifications, Interfaces and Testable Requirements

Unclear requirements are the most common cause of project delays and rework. I create structured business specifications, interface documentation, and testable requirements - so that development, testing, and compliance work from a shared foundation.

When to Engage

  • Requirements are unclear, contradictory, or not formulated in testable terms
  • Interfaces between systems or organizational units are not specified
  • Regulatory requirements need to be translated into actionable specifications
  • Business specifications are missing, outdated, or no longer traceable

Deliverables

Business specifications with clear structure, boundaries, and acceptance criteria
Interface specifications (data models, protocols, responsibilities)
Requirements catalog with testable acceptance criteria
Traceability matrix (requirement - design - test - sign-off)
Stakeholder alignment and sign-off documentation

Working Approach & Quality Assurance

Structured Elicitation: Requirements are systematically gathered - from interviews, workshops, document analysis, and system reviews.

Review Process: Every specification goes through a defined review cycle with business, development, and - where applicable - compliance.

Traceability: Every requirement is traceable - from the business requirement through design to the test case and sign-off.

Regulatory & Audit Alignment

Requirements engineering in regulated environments demands particular traceability. I ensure that:

  • Regulatory requirements are clearly identified and traceable
  • Business specifications meet internal quality and compliance standards
  • Testability and acceptance criteria are documented in audit-ready format

Project contexts are anonymized. Roles and results are truthful; details available under NDA.
