The project
You join Tarnmere Digital Ltd (simulated company)
You are the junior business analyst on a programme to add an AI assistant to supplier invoice handling. The Senior Business Analyst gives you a brief, a draft PRD with mistakes in it, a timing sample, a test of 300 invoices and the client's AI policy. Over four weeks you measure the baseline, write testable requirements, answer a sponsor who wants 100 percent accuracy, check outputs against a contract, and handle payroll pasted into a public chatbot. Then you register AI uses by risk, draft a DPIA, review risks, advise on CV ranking, and find that a model update has broken the pilot's guardrail.
The people in the story are roles, such as Lead Engineer, not real people.
