Back to original languageAbout Ian
Hybrid Product Owner / Business Analyst with a focus on requirements quality, system integration and end-to-end delivery. Experienced in Requirements Engineering, API/interface analysis and agile methods (Scrum/SAFe).
I support companies in creating clear, actionable requirements and robust technical concepts – from requirements gathering, modeling (UML/BPMN) to interface and data flow analysis. Many years of experience in complex system landscapes (CRM, Billing, OSS/BSS, Product Catalog/CPQ) and in collaboration with architecture and development teams.
Typical tasks I undertake:
- Requirements Engineering & User Story Quality
- Interface/API Analysis (REST/SOAP)
- Solution Design & Technical Clarification
- Backlog Management (Epics, Features, User Stories)
- Process Analysis (UML/BPMN)
- Cross-functional Collaboration & Stakeholder Management
Currently engaged in an ongoing part-time mission – available for smaller, clearly defined parallel projects (approx. 2 days/week), e.g., technical analysis, user story reviews, interface clarification, backlog optimization, or E2E analysis.
