Exercise: Forecast Final Cost Calculation

Scenario: A software development project has an initial budget of $500,000. The project is currently 60% complete, and the actual costs incurred so far are $350,000. Based on the remaining work, the project manager estimates that $180,000 will be needed to complete the project.

Task: Calculate the Forecast Final Cost (FFC) for this project.

Techniques

Chapter 1: Techniques for Forecasting Final Cost

This chapter explores the various methods used to forecast final cost, providing a detailed overview of each approach and its strengths and weaknesses.

1.1 Bottom-Up Approach

• Description: This method involves meticulously estimating the cost of each remaining task or activity. These individual cost estimates are then summed to arrive at the total forecast final cost.
• Advantages:
  • Highly accurate when detailed cost information is available.
  • Provides a granular understanding of project costs.
• Disadvantages:
  • Time-consuming and resource-intensive.
  • Requires a high level of expertise and knowledge.
  • Prone to errors if individual cost estimates are inaccurate.

1.2 Top-Down Approach

• Description: This method starts with the initial budget and applies adjustments based on observed performance variances and anticipated changes.
• Advantages:
  • Quick and easy to implement.
  • Useful for projects with limited detailed cost information.
• Disadvantages:
  • Less accurate than the bottom-up approach.
  • Relies heavily on assumptions and may not reflect actual cost drivers.
  • Prone to bias if adjustments are not made objectively.

1.3 Earned Value Management (EVM)

• Description: EVM is a sophisticated method that uses performance metrics like earned value, planned value, and actual cost to forecast future costs.
• Advantages:
  • Provides a comprehensive picture of project performance.
  • Identifies potential cost overruns or underruns early on.
  • Facilitates informed decision-making and risk mitigation.
• Disadvantages:
  • Requires significant effort to set up and implement.
  • Can be complex to understand and interpret.
  • Relies on accurate data and consistent reporting.

1.4 Other Techniques

• Analogous Estimating: Using historical data from similar projects to estimate costs.
• Parametric Estimating: Utilizing statistical relationships between cost drivers and project parameters.
• Expert Judgment: Involving experienced professionals in providing cost estimates.

1.5 Choosing the Right Technique

The most appropriate forecasting technique depends on factors like project complexity, available data, and the level of accuracy required. A combination of approaches may be used to enhance accuracy and provide a more robust forecast.

Chapter 2: Models for Forecasting Final Cost

This chapter explores various models that can be used to calculate and track the forecast final cost.

2.1 Simple Model:

• Description: A basic model that adds the cost of completed work to the estimated cost of remaining work.
• Formula: FFC = Actual Cost (AC) + Estimate to Complete (ETC)
• Advantages:
  • Easy to implement and understand.
  • Suitable for small, simple projects.
• Disadvantages:
  • Ignores potential performance variances and changes.
  • May not provide an accurate forecast.

2.2 Performance-Based Model:

• Description: This model adjusts the initial budget based on observed performance variances.
• Formula: FFC = Initial Budget + (Actual Cost - Planned Value) x (Remaining Work / Total Work)
• Advantages:
  • Incorporates performance data to improve accuracy.
  • Provides insights into potential cost overruns or underruns.
• Disadvantages:
  • Requires accurate performance data and consistent reporting.
  • May be too simplistic for complex projects.

2.3 EVM Model:

• Description: A sophisticated model that uses earned value metrics to calculate the FFC.
• Formula: FFC = (Actual Cost - Earned Value) + Budget at Completion (BAC)
• Advantages:
  • Provides a comprehensive picture of project performance.
  • Offers advanced forecasting capabilities.
  • Facilitates risk identification and mitigation.
• Disadvantages:
  • Requires a significant investment in time and resources.
  • Can be complex to understand and implement.

2.4 Choosing the Right Model:

The choice of model depends on the project's complexity, available data, and the desired level of detail and accuracy. Simple models are suitable for small projects, while more complex models are better suited for larger, more intricate projects.
