IT Business Analyst

Can’t wait to make an impact on the world? You’re not alone. Join us in driving progress in the working world and beyond.

Your journey with us

The IT Business Analyst acts as the bridge between business stakeholders and IT delivery teams, translating business needs into clear requirements and well-designed solutions. Operating within the IT Department, the role contributes to the end-to-end delivery of IT services - from demand intake through requirements, design, testing, and transition into operations - ensuring that technology investments deliver measurable business value, are fit for purpose, and are supported by quality documentation and a smooth handover to service operations. The role combines strong analytical thinking, skilled stakeholder elicitation, and hands-on command of core business analysis methodologies and modelling frameworks.

Key Responsibilities

1. Analytical Thinking & Problem Structuring

• Structure ambiguous or poorly defined business problems into clear problem statements, using techniques such as root-cause analysis (5 Whys, fishbone/Ishikawa) to distinguish symptoms from underlying causes.
• Perform impact, feasibility, and cost-benefit analysis for proposed changes, making explicit assumptions where data is incomplete.
• Adjudicate conflicting requirements between stakeholders using prioritisation frameworks (e.g. MoSCoW) and traceability back to the business objective.
• Manage scope discipline by maintaining a requirements baseline and escalating scope creep rather than absorbing it silently.

2. Stakeholder Elicitation & Influence

• Elicit, document, and validate business requirements through workshops, structured interviews, shadowing/observation, and prototyping/mock-ups.
• Act as the primary liaison between business units and IT during project initiation, design, and delivery, managing expectations against IT roadmap and capacity.
• Facilitate requirements workshops and design reviews, using pre-work, structured agendas, and parking-lot techniques to keep senior stakeholders engaged within limited time.
• Validate documented requirements through stakeholder walkthroughs and sign-off, using visual models as a shared reference point to confirm understanding across language and cultural differences.

3. Methodology, Modelling & Documentation

• Produce as-is and to-be process maps using BPMN (pools, lanes, gateways, events) at an audience-appropriate level of detail, to identify gaps, inefficiencies, and automation opportunities.
• Use Data Flow Diagrams (DFDs) and data mapping techniques to analyse system integrations and clarify how data moves, is stored, and is transformed between systems (e.g. CRM/ERP).
• Translate business requirements into functional specifications, user stories (INVEST-aligned), and acceptance criteria (e.g. Given/When/Then) for IT delivery teams.
• Maintain end-to-end requirements traceability from business need through to test cases and UAT sign-off, using a requirements traceability matrix or equivalent.
• Apply the right technique for the context - flexing between Agile artefacts (backlogs, epics, story maps) and traditional BRD/FRD-style documentation depending on project type and stakeholder maturity.
• Contribute to project documentation in line with the IT SSDLC, including business cases, requirement specifications, and test plans.

4. Delivery Support & Continuous Improvement

• Support project managers and product owners with scoping, prioritisation, and backlog management.
• Coordinate User Acceptance Testing (UAT), log defects, and track resolution to closure.
• Support change management activities, including communication plans and training materials.
• Ensure deliverables align with IT governance, compliance (GDPR, NIS2), and data quality standards.
• Identify and progress opportunities for process optimisation and automation (Power Platform).
