Each mini example includes a what it shows, when to use, and a short exam cue.
Quality Charts
Pareto (80/20) — Prioritize Vital Few
What: Bars sorted by frequency with a cumulative line to highlight the “vital few”.
Use when: You need to pick which defect categories to attack first.
Exam cue: 20% of causes ≈ 80% of problems. Often paired with Fishbone.
Control Chart — Process Stability
What: Time-series of measurements vs. control limits.
Use when: Monitoring for special-cause variation.
Exam cue: Spec limits (customer) ≠ control limits (process capability).
Ishikawa / Fishbone — Root Cause
What: Cause categories feeding into an effect.
Use when: Brainstorming and organizing potential root causes.
Exam cue: Methods, Machines, Materials, People, Measurement, Environment.
Risk Tools
Probability–Impact Matrix — Qualitative Ranking
What: Grid ranking risks by probability and impact.
Use when: Prioritizing risks for qualitative analysis; create a watch list for low priority.
Exam cue: Outputs feed into Plan Risk Responses (owners, strategies).
Tornado Diagram — Sensitivity (Quantitative)
What: Bars sorted by impact width to show most sensitive variables.
Use when: Identifying which factors drive outcome variability.
Exam cue: Often appears with Monte Carlo and Decision Tree (EMV).
Decision Tree (EMV) — Choose Best Option
What: Branches represent decisions and chance outcomes; expected value sums p×impact.
Use when: Comparing mutually exclusive alternatives under uncertainty.
Exam cue: Pick the option with highest EMV (unless risk policy dictates otherwise).
Schedule & CPM
Critical Path Network — Longest Path
What: Precedence network showing dependencies.
Use when: Determining project duration and float.
Exam cue: Compression: Crashing (adds cost) vs. Fast Tracking (adds risk).
Gantt (Baseline vs Actual) — Tracking
What: Bars show planned vs actual durations.
Use when: Communicating schedule performance at a glance.
Exam cue: Baseline changes only via Integrated Change Control.
Cost / EVM
S‑Curve — EV, PV, AC
What: Cumulative curves for EV, PV, AC.
Use when: Assessing cost/schedule performance trends.
Exam cue: CPI=EV/AC, SPI=EV/PV, EAC≈BAC/CPI when variance persists.
Stakeholders & Roles
RACI — Role Clarity
What: Responsibility Assignment Matrix—who’s Responsible, Accountable, Consulted, Informed.
Use when: Planning resources and clarifying decision authority.
Exam cue: Ensure one A per task; avoid “multiple Accountables”.
Stakeholder Power/Interest Grid — Strategy by Quadrant
What: Classifies stakeholders to tailor engagement strategy.
Use when: Identifying and planning stakeholder engagement.
Exam cue: Strategies: Manage Closely, Keep Satisfied, Keep Informed, Monitor.
