Business Analyst
A business analyst turns ambiguity into requirements, test cases, and specifications a delivery team can build against. This pillar covers that work in practice: writing requirements developers can implement, prioritizing with MoSCoW, building a traceability matrix, and turning a one-line business request into a functional spec. Every article here is written for analysts already on a delivery team, with real artifacts you can adapt rather than theory.
