Lesson 1 of 6
Predictive/Waterfall Characteristics
Recognize when a scenario is operating in a predictive mode and how that changes planning, approvals, and control actions.

Predictive Context Signals
Predictive stems describe detailed upfront planning, phased execution, and formal approval checkpoints. Scope stability is emphasized, and changes require structured evaluation. The best answers respect documentation, impact analysis, and authorized decision paths—while still communicating transparently when pressure rises.
Common Predictive Clues in Questions
- References to baselines, formal sign-off, or change control board review.
- Sequential phase language: design before build before test before deploy.
- Heavy dependence on upfront requirements and WBS completeness.
- Fixed-price contracts, regulatory gates, or audit checkpoints.
- Earned value metrics, critical path, and milestone acceptance.
Best-Answer Sequence for Predictive Stems
- 1Confirm the issue or change request in measurable terms.
- 2Assess integrated impact on scope, schedule, cost, quality, risk, and resources.
- 3Develop options with tradeoffs—not a single forced recommendation.
- 4Route through the authorized change or approval path.
- 5Update approved plans and communicate to affected stakeholders.
Predictive Response Quality
Weak Option
- Implements a sponsor request informally to save time.
- Skips impact analysis because the deadline is tight.
- Rebaselines locally without change board approval.
- Commits to dates before consulting the team.
Strong Option
- Documents impact and follows formal change control.
- Communicates early while governance runs in parallel.
- Protects baseline integrity with authorized updates only.
- Balances urgency with integrated planning discipline.
Formal does not mean slow. Strong predictive answers initiate the correct process promptly and keep stakeholders informed—they do not stall with unnecessary meetings or bypass governance entirely.
In predictive settings, protect baseline integrity while communicating impact early.
