Predictive methodologies

Earned Value Management integrates scope, schedule, and cost metrics by using Planned Value, Earned Value, and Actual Cost to measure project performance. Option A is incorrect because relying solely on planned value fails to account for actual progress and expenditures, preventing variance analysis.

A predictive lifecycle is commonly called Waterfall because project phases flow sequentially from one to the next after thorough upfront planning. In contrast, Agile is an adaptive approach that focuses on iterative development and flexibility rather than rigid, upfront predictions.

A predictive lifecycle is commonly called Waterfall because project phases flow sequentially from one to the next after thorough upfront planning. A diagram for this topic isn't available yet — the worked example below walks the same reasoning step by step.

• !A predictive lifecycle is commonly called Waterfall because project phases flow sequentially from one to the next after thorough upfront planning.
• !Option A is incorrect because the shortest path does not determine the project's overall duration and typically contains float.
• !Option A is incorrect because relying solely on planned value fails to account for actual progress and expenditures, preventing variance analysis.
• !Dividing EV by Actual Cost (AC) is incorrect because that formula calculates the Cost Performance Index (CPI) instead.
