A project manager is initiating a project to develop a new mobile application. The business environment is highly uncertain, and requirements are expected to evolve frequently. Which business analysis framework is most appropriate for this scenario?
Trap 1: Waterfall
Waterfall fixes scope, schedule and cost baselines before build begins, so late requirement changes force formal change requests and rework of completed phases. It suits stable, well-understood deliverables such as regulatory or construction projects. Here, evolving requirements demand iterative delivery, which Waterfall's sequential gating cannot accommodate.
Trap 2: PRINCE2
PRINCE2 governs delivery through defined stages, tolerances and a product-based plan, so it assumes requirements can be baselined at stage boundaries — the opposite of continuously evolving scope. It is tempting because PRINCE2 excels at controlled, governance-heavy projects with stable, pre-agreed outputs, where its stage-gate structure genuinely adds value.
Trap 3: Six Sigma
Six Sigma reduces process variation through DMAIC and statistical control, which assumes stable, measurable processes rather than emergent requirements. It suits manufacturing or service delivery seeking defect reduction. Here, evolving mobile-app requirements demand iterative elicitation and adaptive scope, which Six Sigma's define-measure-analyse-improve-control cycle does not accommodate.

Agile (Scrum)
Agile (Scrum) suits volatile requirements through iterative sprints, delivering working increments every two to four weeks so feedback reshapes the backlog continuously. This directly satisfies the stem's highly uncertain environment and frequently evolving requirements, which predictive frameworks cannot accommodate without costly change control.
