DESCRIPTION OF THE SERVICES:
DRIVE CLARITY IN COMPLEX ENVIRONMENTS:
- Shaping requirements and driving alignment in ambiguous situations, with minimal direction
- Adapting to different delivery models across products, including engineering-led and BA-led ways of working
- Define and maintain functional and non-functional requirements — including operational scenarios, acceptance criteria, and QA validation needs across distributed workflows
- Ensuring questions are raised early, so that solutions are well understood, well defined, and ready to be delivered
SHAPE THE BACKLOG AND DELIVERY:
- Collaborate with engineering, QA, and architecture teams to translate complex technical solutions into structured backlog items, deliverable stories, and testable outcomes
- Help stakeholders make their vision for the product materialise, especially in the early stages of each delivery phase
- Be the stakeholders' proxy in the team — able to make quick, firm decisions on scope, requirements and prioritisation/triage
- Drive backlog review and estimation processes, and take part in planning activities
- Define acceptance criteria and tests up front as part of a Business-Driven Development approach
- Follow up during implementation and testing phases to ensure delivery satisfies requirements
COLLABORATE ACROSS THE TEAM:
- Work closely with QA to assess failure scenarios and help distinguish bugs, enhancements, and new feature requirements
- Facilitate discussions across technical and business stakeholders to drive clarity, alignment, and sound decision-making
- Support delivery, implementation, and release processes, ensuring solutions align with business objectives, customer use cases, and non-functional expectations
- Help improve operational processes and workflows — both internally and externally — bringing a calm, pragmatic and collaborative approach
