Terminal Learning ObjectiveTerminal Learning Objective• Task: Apply Earned Value Management Principles
to Case Study Scenario• Condition: You are training to become an ACE
with access to ICAM course handouts, readings, and spreadsheet tools and awareness of Operational Environment (OE)/Contemporary Operational Environment (COE) variables and actors.
• Standard: with at least 80% accuracy• Identify key variables from case study data• Calculate BAC, schedule and cost variances, and EAC

Building the Great PyramidBuilding the Great PyramidCase A: The Air Force ApproachCase A: The Air Force Approach
• Read the paper “If the Pharaoh Had Only Used an Earned Value System in Building the Pyramids”
• By LTC Neimann (USAF Ret) found at https://acc.dau.mil/CommunityBrowser.aspx?id=19572
• Using the tools learned:• Build and verify the BAC presented in the paper• Determine schedule variance at Year 12• Determine the cost variance at Year 12• Calculate EAC at Year 12

• We are now behind schedule and over cost: terrible!!
• ACWP is 130% of BCWP so EAC can be projected at 130% of BAC: (1.30)20M = 26M

Building the Great PyramidBuilding the Great PyramidCase B: Corps of EngineersCase B: Corps of Engineers
• The Pharaoh was quite displeased with the Air Force Pyramid Building Project’s AAR results• LTC Neimann was re-assigned to flying carpets and
moved to a lovely tent in the Sinai where he soon retired
• The Pharaoh turned to the Corps of Engineers• He asked for project proposals to complete the Great
Pyramid within four years• The Corps of Engineers tasked six teams to make
proposals to complete an enhanced, Army-ized Army-ized pyramid

• Is the Nation’s number one federal provider of outdoor recreation• Owns and operates more than 600 dams• Operates and maintains 12,000 miles of commercial inland navigation channels• Dredges more than 200 million cubic yards of construction and maintenance
dredge material annually• Maintains 926 coastal, Great Lakes and inland harbors• Restores, creates, enhances or preserves tens of thousands of acres of wetlands
annually under the Corps’ Regulatory Program• Provides a total water supply storage capacity of 329.2 million acre-feet in major
Corps lakes• Owns and operates 24 percent of the U.S. hydropower capacity or 3 percent of the
total U.S. electric capacity• Manages an Army military construction program between 2006 and 2013 totaling
approximately $44.6 billion between—the largest construction effort since World War II

Team Design Options:Team Design Options:Pick Two from Left and Three from RightPick Two from Left and Three from Right
Take advantage of Corps’ Core Competencies• Add a dam and lake to
provide recreational venue for tourists and pilgrims
• Divert the Nile River to ease transportation to site
• Build levees around pyramid to eliminate any flooding threat
• Build barracks facilities for workers and guests
• Up to one more of your choice
Army-ize the project in the interests of National Defense
• Camouflage the pyramid• Add armor• Build system of mutually
supporting archer nests• Build roads for rapid
reaction chariot forces • Up to two others of your
choice

Task 1: Build Your BACTask 1: Build Your BAC• Build your work breakdown structure given your
choices from the previous page• Assume each task takes two years• Don’t ignore need for more blocks and the assembly
task• You should have seven tasks (blocks, assembly, two corps’
core competency, and three Army-ize)• Estimate cost for each task for years 1, 2, 3, 4 (in year
3000 BC shekels) • Present your design, work schedule and graph of BCWS
to the class• Make sure you don’t exceed the $13M the Air Force had
estimated for added cost to completion© Dale R. Geiger 2011 13

Task 2: AAR for the PharaohTask 2: AAR for the Pharaoh
• Generate actual cost and schedule per following page’s instructions
• Present to class• Cost and schedule variances for each year until completion
(4+ slides)• BAC and EAC for the first year (1 slide)• Graph of BCWS, BCWP, ACWP (1 slide)• A reconciliation of your variance results at completion (1
slide)• Suggestions for continuous improvement (1 slide) • A view of what your finished pyramid looks like (1 slide)

Task 2: Developing Actual Task 2: Developing Actual Cost and ScheduleCost and Schedule
• Use the randbetween formula in Excel to generate a random number between 1 and 10 for each task: =RANDBETWEEN(1,10)
• Follow the instructions on the next page to find what happened to the actual cost and schedule for that task
• Determine the actual results of the project year by year

Task 2: Reality HitsTask 2: Reality Hits
1 Freak rain storms wash out a year’s progress: add year at same cost
2 Assyrians attack but are easily defeated: however, add 20% to task cost
3 Engineering error: task takes a third year at same average cost per year
4 Outsourcing accelerates progress, raises 1st year cost 50% but completes task
5 Slaves rebel: add 50% to task cost
6 Conquests add slaves to workforce: cut task cost 30% & finish one year early
7 Dust storms disrupt work: add 20% to task cost
8 Hidden Air Force funds discovered: reduce task cost 50%
9 LSS improves process: eliminate 2nd year and its cost
10 Finance Corps ACES assigned to project: reduce cost of all tasks 10%

• Get more ACES and involve them more • Check Engineering designs before they create
major cost overruns• Double check Engineering designs• Look for more outsourcing opportunities
