Earned Value Analysis: A Project Budget Guide

Earned Value Analysis A Project Budget Calls For The Following Expend

Perform an earned value analysis for a project based on the provided expenditures and schedule. Define each term involved, calculate the necessary values for this specific project scenario, and illustrate your calculations clearly with explanations. The project tasks include building forms, pouring the foundation, framing walls, and remaining tasks beyond July 1, with specified budgets and dates. Calculate the budgeted cost baseline, budget at completion, planned value as of May 1, earned value as of May 1 considering foundation completion, schedule variance, cost variance, schedule performance index, cost performance index, estimate to complete, and estimate at completion.

The effective management of projects hinges on thorough monitoring and control techniques, among which earned value analysis (EVA) stands out as a comprehensive method for integrating scope, schedule, and cost parameters. This analysis provides project managers with quantitative measures to assess project performance and forecast future performance based on current data. The scenario outlined necessitates calculating several key EVA metrics based on given project expenditures, schedules, and completion statuses. To perform a meticulous and accurate analysis, each component must be clearly understood and diligently computed.

1. Definition of Key Terms

Before delving into calculations, it is essential to define the fundamental terms associated with earned value analysis:

  • Budgeted Cost Baseline (BCB): The approved cost plan plotted over the project's scheduled timeline, illustrating the planned expenditures at various points.
  • Budget at Completion (BAC): The total budget allocated for the entire project, representing the projected total cost if the project is completed as planned.
  • Planned Value (PV): The budgeted cost assigned to work scheduled to be completed by a specific date.
  • Earned Value (EV): The budgeted cost of work actually performed by a specific date, reflecting the value of completed work.
  • Schedule Variance (SV): The difference between EV and PV; indicates whether the project is ahead, behind, or on schedule.
  • Cost Variance (CV): The difference between EV and actual costs; reveals cost performance relative to the plan.
  • Schedule Performance Index (SPI): The ratio of EV to PV; measures schedule efficiency.
  • Cost Performance Index (CPI): The ratio of EV to actual costs; measures cost efficiency.
  • Estimate to Complete (ETC): The forecasted cost needed to complete remaining work, assuming current performance levels continue.
  • Estimate at Completion (EAC): The forecasted total cost of the project, combining actual costs and ETC. okay

2. Calculation of Values

The project tasks and data points are as follows:

  • Build Forms: April 1; Budgeted $10,000
  • Pour Foundation: April 1 - May 1; Budgeted $50,000, Actual expenditure estimate as of May 1 is $160,000 (with foundation two-thirds complete)
  • Frame Walls: May 1 - June 1; Budgeted $30,000
  • Remaining Tasks: July 1 and beyond; Budgeted $500,000

2.1. Budgeted Cost Baseline (BCB)

The BCB is the sum of budgets over time, reflecting planned expenditures. Constructing this as a graph would involve plotting cumulative planned costs over elapsed time. For this scenario, the baseline is as follows:

  • April 1: $10,000 (Build Forms)
  • April 1 - May 1: $50,000 (Pour Foundation); cumulative $60,000
  • May 1 - June 1: $30,000 (Frame Walls); cumulative $90,000
  • Beyond June 1: Remaining $500,000

Graphically, the baseline shows step increases at each schedule milestone, with the cumulative planned cost rising from $10,000 to $60,000, then to $90,000, and eventually to the total BAC of $590,000.

2.2. Budget at Completion (BAC)

The BAC is the total sum of all budgets for the project:

BAC = $10,000 + $50,000 + $30,000 + $500,000 = $590,000

2.3. Planned Value (PV) as of May 1

The PV as of May 1 includes all work scheduled to be completed by this date. By May 1, the scheduled work includes:

  • Build Forms: Completed on April 1, so PV = $10,000
  • Pour Foundation: Scheduled May 1, so PV = $50,000 (full planned work for this task by May 1)

Therefore, PV as of May 1: $10,000 + $50,000 = $60,000

2.4. Earned Value (EV) as of May 1

The foundation work is two-thirds complete as of May 1, and everything else is on schedule.

  • Build Forms: Already completed; EV = $10,000
  • Pour Foundation: Two-thirds complete; EV = (2/3) × $50,000 = $33,333
  • Frame Walls: On schedule; scheduled to start after May 1, so EV for this remains $0 at this point

Sum of EV: $10,000 + $33,333 = $43,333

2.5. Schedule Variance (SV) as of May 1

SV = EV – PV = $43,333 – $60,000 = −$16,667

Negative SV indicates the project is behind schedule relative to plan as of May 1.

2.6. Actual Cost (AC) as of May 1

Given: AC = $160,000

Cost Variance (CV) = EV – AC = $43,333 – $160,000 = −$116,667

This reveals significant cost overruns at this point.

2.7. Schedule Performance Index (SPI)

SPI = EV / PV = $43,333 / $60,000 ≈ 0.722

An SPI less than 1 signals the project is progressing at a rate slower than planned.

2.8. Cost Performance Index (CPI)

CPI = EV / AC = $43,333 / $160,000 ≈ 0.271

A CPI well below 1 indicates poor cost efficiency, with actual costs far exceeding earned value.

2.9. Estimate to Complete (ETC)

Assuming current performance levels persist, ETC is calculated as:

ETC = (BAC – EV) / CPI = ($590,000 – $43,333) / 0.271 ≈ ($546,667) / 0.271 ≈ $2,016,563

This indicates an unexpectedly high future cost, likely due to the current cost overruns and the low CPI value.

2.10. Estimate at Completion (EAC)

The EAC, considering actual costs and future performance, is:

EAC = AC + ETC = $160,000 + $2,016,563 ≈ $2,176,563

This suggests the total project cost may significantly exceed the initial budget, primarily due to inefficiencies observed.

Conclusion

The calculations reveal critical insights into project performance. The negative schedule and cost variances, combined with low SPI and CPI, warn of delays and cost overruns. Immediate corrective actions are essential to align the project with its planned objectives, including reassessment of resource allocation, scope adjustments, and enhanced oversight. Accurate and timely data collection is vital for ongoing monitoring, enabling proactive management and eventual project success. Earned value analysis, thus, remains a vital tool in modern project management for maintaining control and ensuring project delivery within scope, time, and budget constraints.
