2. In-Depth Breakdown

Business Analyst (BA)

The Business Analyst acts as a bridge between business stakeholders and technical teams. Their primary role is to understand business problems, analyze processes, and translate high-level business goals into precise functional and technical specifications (such as BRDs, FRDs, and detailed User Stories).

• Core Responsibilities:

  • Eliciting requirements through workshops, interviews, and process modeling.

  • Creating detailed documentation (BRD, FRD, Process Flow Diagrams, Gap Analysis).

  • Defining acceptance criteria and validating end-user requirements.

  • Performing root-cause and feasibility analysis for business requests.

Product Owner (PO)

The Product Owner is a key role within the Scrum Framework responsible for maximizing the value of the product resulting from the team’s work. The PO owns the Product Backlog and represents the customer’s voice inside the Sprint ecosystem.

• Core Responsibilities:

  • Defining the product vision, roadmap, and release strategy.

  • Maintaining and prioritizing the Product Backlog items based on ROI and business value.

  • Writing high-level User Stories and defining Definition of Done / Acceptance Criteria.

  • Making clear trade-off decisions on scope versus timelines.

Scrum Master (SM)

The Scrum Master is a servant-leader and coach for the Scrum team. Rather than managing people or defining what gets built, the SM focuses entirely on how the team works, ensuring Scrum principles are practiced and removing obstacles that slow the team down.

• Core Responsibilities:

  • Facilitating Scrum events (Daily Standups, Sprint Planning, Reviews, and Retrospectives).

  • Removing roadblocks, impediments, and external distractions for the development team.

  • Coaching team members and the organization on Agile/Scrum practices.

  • Fostering team efficiency, psychological safety, and continuous improvement.

• Product Owner (PO): Evaluates overall customer impact versus checkout cart abandonment rates. Prioritizes the refund epic at the top of the backlog to hit Q3 retention targets.

• Scrum Master (SM): Identifies that developers are waiting on payment API access from a third party. Schedules necessary technical calls, removes access blockers, and keeps the sprint velocity on track.
