Management
Colonel John Keesee

Objective
? To introduce and discuss the fundamentals
of earned value project management
?Work Breakdown Structures
?Program plans and schedules
?Earned value management systems
?Cost and schedule variances
?Estimates at completion
3
Scenario
? You have been tasked to be the project
manager for an important project
?You have been directed to use an earned
value management system
?Time to market is critical for this
development
4
Work Breakdown Structure
? Identifies 100 % of the work to be
accomplished
? WBS dictionary breaks the scope into
measurable tasks
?Each with an estimated value
?Responsibility for each task assigned to
individuals or work teams
5
Work Breakdown Structure

Payload Spacecraft Reentry vehicle Integration, Assembly,
Test and Checkout
Space Vehicle Ground Command,
Control, Communications
and Mission Equipment

Project Master Schedule
? Detailed plan and schedule
? Identified dependencies between tasks
?18 months
? Estimated resources for each task
?10 units at $150K each

Plan Review Before Go-Ahead
? CEO:
?“Time to market is critical. You have 12
months.”
?“This looks gold-plated at $1.5M. You
have $1.0M.”
?“Go ahead, but come back to me with
your progress in three months.”
10
The Three Month Review
? Three units scheduled for completion
? Two units actually completed
? $300,000 budgeted at this point
? $300,000 actually spent
? Optimist PM: “A little behind schedule but
right on the cost plan.”
11
Earned Value System
? Requires a detailed, bottoms-up
performance plan
? Performance measured against the plan
? Provides forecast of final expected results
based on data
12
Earned Value Measurements
1. Work scheduled
2. Budgeted cost of work scheduled (BCWS)
3. Work performed
4. Budgeted cost of work performed (BCWP)
5. Actual cost of work performed (ACWP)
6. Schedule variance (SV) = BCWP - BCWS
7. Cost Variance (CV) = BCWP - ACWP

Management Reserve
? Budgeted to provide the ability to adjust for
uncertainty
? Always accounted at the total project level
? Normally retained and controlled at the total
project level
? Must not be eliminated by negotiations
16
Summary
? Earned value management system provides
a key link between the cost, schedule, and
technical aspects of a project
? Provides an early and reliable prediction of
future performance
