13.7 From Appendix 13.1: Understand the advantages of Earned Schedule methods for determining project schedule variance, schedule performance index, and estimates to completion.

P M B o K Core Concepts

Project Management Body of Knowledge (P M B o K ) covered in this chapter includes:

Control Schedule (P M B o K 6.7)

Control Costs (P M B o K 7.4)

Earned Value System (P M B o K 7.4.2.1)

Forecasting (P M B o K 7.4.2.2)

Performance Reviews (P M B o K 7.4.2.4)

Control Cycles—General Model

Setting a goal.

Measuring progress.

Comparing actual with planned performance.

Taking action.

Milestone Analysis

Milestones are events or stages of the project that represent a significant accomplishment.

Milestones:

Signal completion of important steps

Motivate team and suppliers

Offer reevaluation points

Help coordinate schedules

Identify key review gates

Signal other team members when their participation begins

Delineate work packages

Project status is updated by linking task completion to the schedule baseline.

Earned Value Management

Earned Value Management (E V M) recognizes that it is necessary to jointly consider the impact of time, cost, and project performance on any analysis of current project status.

Earned Value (E V) directly links all three primary project success metrics (cost, schedule, and performance).

Earned Value Terms

Planned value (P V)

Earned value (E V)

Actual cost of work performed (A C)

Schedule variance (S V) and schedule performance index (S P I)

Cost variance (C V) and cost performance index (C P I)

Budgeted cost at completion (B A C)

Estimate at completion (E A C)

Steps in Earned Value Management

Clearly define each activity including its resource

needs and budget.

Create usage schedules for activities and resources.

Develop a time-phased budget (P V).

Total the actual costs of doing each task (A C).

Calculate both the budget variance (C V) and schedule

variance (S V).

Earned Value Example

Schedule Variances

Planned Value (P V) = 103

Earned Value (E V) = 44

Cost Variances

Cumulative Actual Cost of Work Performed (A C) = 78
