Business Analysis Oral Examination
What the examination is
The Business Analysis Oral Examination is the capstone assessment of the BCS International Diploma in Business Analysis. It is a structured professional discussion - typically around 50 minutes, conducted by two examiners - built around a written submission in which you describe a real piece of business analysis work you personally carried out. The submission sets the agenda; the examiners use it to test whether you can apply the diploma syllabus (business analysis practice, requirements engineering, business process modelling, and the organisational and stakeholder context) to your own practice, and explain why you made each choice you made.
The submission is the spine of the exam
Write about work you personally decided and performed, not work you merely observed. Choose a project broad enough to show context, stakeholders, investigation, modelling, requirements, options and outcome, and anonymise the client so you can talk freely. Every claim in it is fair game: "I ran a facilitated workshop to agree the to-be process" invites "why a workshop?", "who attended?", "what would you do differently?"
Answering under questioning
- Name the technique, then justify it against the alternative you rejected.
- Show the theory behind the practice - CATWOE for a root definition, MoSCoW for prioritisation, fishbone for root-cause analysis.
- Be able to walk an examiner through an artefact you produced, such as an activity model or a requirements catalogue.
- Concede gaps with reasoning; a defended omission scores better than a bluff.
Worked example
A candidate writes: "I used a workshop to elicit requirements." Examiner: "Why not interviews?" Strong answer: six stakeholders across three departments held conflicting views of the approvals process; a facilitated workshop exposes conflict early and produces one shared model, whereas separate interviews would yield six incompatible lists. Then the trade-off: workshops are hard to schedule and can be dominated by one voice, so the as-is model was circulated beforehand and elicitation ran round-robin. That answer demonstrates technique selection, risk awareness and reflection - the three things examiners listen for.
Traps that cost marks
- Reciting definitions instead of describing your own decisions.
- Being unable to say what you would change with hindsight.
- Blaming stakeholders rather than analysing their influence and interest.
- Ignoring commercial context: benefits, costs, risks, the business case.
- Failing to trace requirements back to business objectives.
