PBP: Foundational Knowledge and Terminology

The PBP Foundational Knowledge and Terminology domain tests whether you can use the exam's vocabulary precisely and recognize when two familiar terms are being confused. Questions often hinge on a single definition, not on calculation.

Terms that carry marks

• Output vs outcome: an output is a delivered product or task; an outcome is a resulting change in behavior, capability, or performance.
• Efficiency vs effectiveness: efficiency is resource use; effectiveness is goal attainment.
• Risk vs issue: a risk is uncertain and future; an issue is current and already affecting objectives.
• Assumption vs constraint: an assumption is believed true without proof; a constraint is a limit.
• Governance vs management: governance sets direction, decision rights, and oversight; management executes within them.
• Stakeholder vs rightsholder: a stakeholder has an interest or influence; a rightsholder has a right, claim, or entitlement.

Worked example

A team reports 95% of tasks completed on time, but customer complaints rise. On-time task completion is an output and an efficiency signal. Complaint rate is an outcome and an effectiveness signal. The correct conclusion is not that the team is performing well; it is that delivery activity is high while the intended customer result is not being achieved, so investigate quality and requirements fit.

Traps that cost marks

Treating an issue as a risk, calling every interested party a stakeholder, using scope change for an approved change, and treating monitoring as control. Monitoring collects performance information; control compares it with the baseline and takes corrective action.

Exam habit

Define the term in one sentence, then test the scenario against that definition. If the term does not change the decision, it is probably a distractor.
