PMP Exam Preparation: Essential Glossary of Project Management Terms

Exam Tip: If a question describes a project with high uncertainty or rapidly changing requirements, look for answers involving "Adaptive" or "Agile" methodologies rather than "Predictive" ones.

Scope, Schedule, and Cost Management

These three elements form the "Triple Constraint" (or Project Management Triangle) of any project.

Scope Management

To prevent Gold Plating—the practice of adding unrequested scope that provides no extra value—project managers use Decomposition to break down the project into a Work Breakdown Structure (WBS). A vital principle here is the 100 Percent Rule, which ensures the WBS captures all known scope and that the sum of the lower-level work rolls up exactly to the higher levels.

Schedule Management

The Critical Path Method (CPM) is used to identify the longest sequence of activities, which determines the shortest possible project duration. To manage this, project managers use:

• Forward Pass: To determine early start and finish dates.
• Backward Pass: To determine late start and finish dates.
• Total Float: The amount of time an activity can be delayed without delaying the project finish date.

When a schedule is slipping, you can use Crashing (adding resources to shorten duration, which increases cost) or Fast Tracking (performing activities in parallel, which increases risk).

Cost Management

Performance is often measured using Earned Value Management (EVM). You must be comfortable with the following metrics:

• Cost Variance (CV): The difference between earned value and actual cost. $CV = EV - AC$
• Cost Performance Index (CPI): A measure of cost efficiency. $CPI = \frac{EV}{AC}$
• Budget at Completion (BAC): The total planned budget for the project.

Risk, Quality, and Decision-Making

Risk Strategies

When managing risks, you must choose a strategy based on whether the risk is a threat or an opportunity:

• Threats: You can Avoid (remove the risk), Accept (acknowledge it but take no action), or Escalate (move it to a higher level).
• Opportunities: You can Enhance (increase probability/impact) or Exploit (ensure it happens).

Quality Management

Quality is managed by balancing the Cost of Quality (CoQ). This includes the Cost of Conformance (prevention and appraisal) and the Cost of Nonconformance (internal and external failures, such as rework or warranty claims).

Root Cause Analysis

To solve problems effectively, project managers use tools like the 5 Whys Method (asking "Why?" repeatedly until the root cause is found) and Cause and Effect (Fishbone/Ishikawa) Diagrams.

Procurement and Contracts

The type of contract chosen significantly impacts how risk is shared between the buyer and the seller:

Exam Tip: In a Cost-Reimbursable contract, the buyer is responsible for the "allowable costs" incurred by the seller.

Communication and Stakeholders

Effective project management relies on Active Listening—clarifying messages to ensure the sender's intent matches the receiver's understanding. Furthermore, you must manage Stakeholders—individuals or groups who can affect or be affected by the project. Tools like the Stakeholder Register and Stakeholder Engagement Assessment Matrix are essential for identifying and planning how to involve these individuals throughout the project lifecycle.
