Responsibilities

• Translate business goals and user needs into product opportunities with clear value hypotheses
• Prototype solutions early and often — directly, to validate ideas before committing to full build
• Define scope collaboratively with stakeholders, keeping scope anchored to user value rather than feature count
• Track and communicate the impact of what ships; deliver outcome, not just the output
• Write and review technical requirements and acceptance criteria that leave no ambiguity at implementation time
• Assess feasibility early and frame build-vs-integrate trade-offs in terms of delivery impact, risk and value
• Be the last line of defense on quality: review and test deliverables against requirements
• Identify and highlight technical debt and systemic risks before they become blockers
• Keep system documentation live and accurate - treated as a product asset
