In the world of project management, planning is everything. From setting goals to defining budgets, every step must be meticulously laid out to ensure the project stays on track and delivers the desired outcome. This is where the concept of Baseline at Completion (BAC) comes into play, serving as a fundamental building block for successful project execution and control.
What is Baseline at Completion (BAC)?
BAC refers to the total estimated cost of work as originally planned. It is the starting point for all cost-related project management calculations and serves as a benchmark against which actual costs are compared. Essentially, BAC represents the ideal scenario - the projected cost of completing the project according to the initial plan.
Why is BAC so important?
Example:
Imagine a project with a BAC of $1 million. As the project progresses, actual costs may deviate from the initial estimate. If the actual costs reach $1.2 million, the cost variance is -$200,000, indicating an overspending situation. This information can then be used to analyze the causes of the deviation and take necessary corrective measures.
Beyond the Basics:
While BAC is a crucial concept, it's important to understand that it is not set in stone. Changes in project scope, unforeseen circumstances, or market fluctuations can necessitate adjustments to the BAC. This is where Earned Value Management (EVM) comes into play. EVM uses BAC as a starting point but also considers the actual work completed and the value earned to date. This provides a more dynamic and realistic picture of project performance.
Conclusion:
Baseline at Completion (BAC) is an essential component of effective project management. It serves as a foundation for planning, monitoring, and controlling costs, fostering transparency and promoting accountability. By utilizing BAC effectively, project teams can establish clear financial targets, track progress accurately, and make informed decisions to ensure project success.

Scenario:
You are managing a software development project with an initial budget of $500,000. You have completed 60% of the project, and the actual cost incurred so far is $350,000.
Task:
1. Calculating BAC:
Since 60% of the project is completed and the actual cost is $350,000, we can calculate the BAC using the following formula:
BAC = (Actual Cost / Percentage Completed) BAC = ($350,000 / 0.60) BAC = $583,333.33
Therefore, the Baseline at Completion (BAC) for this project is $583,333.33.
2. Calculating Cost Variance:
The Cost Variance (CV) is calculated using the following formula:
CV = BAC - Actual Cost CV = $583,333.33 - $350,000 CV = $233,333.33
Therefore, the Cost Variance (CV) for the project is $233,333.33.
3. Interpreting CV:
A positive Cost Variance (CV) indicates that the project is under budget. In this case, the CV of $233,333.33 suggests that the project is currently performing well financially, and the actual cost is less than the estimated cost.
This document expands on the initial introduction to Baseline at Completion (BAC) by providing dedicated chapters exploring techniques, models, software, best practices, and case studies.
Chapter 1: Techniques for Determining BAC
Determining an accurate BAC is crucial for successful project management. Several techniques contribute to this process:
Work Breakdown Structure (WBS): The WBS is a hierarchical decomposition of the project into smaller, manageable work packages. Each work package is estimated for cost and time, providing a detailed breakdown contributing to the overall BAC. The accuracy of the BAC relies heavily on the comprehensiveness and accuracy of the WBS.
Bottom-Up Estimating: This approach involves estimating the cost of individual work packages and then aggregating these estimates to arrive at the total project cost (BAC). It’s more accurate than top-down but requires significant detail and effort.
Top-Down Estimating: This method uses historical data or analogous projects to estimate the overall project cost. It's quicker than bottom-up but less precise. It's suitable for projects with less detail or early-stage planning.
Three-Point Estimating: This technique mitigates the risk of inaccurate estimates by considering three different estimates for each work package: optimistic, pessimistic, and most likely. A weighted average of these estimates provides a more realistic cost for each package, contributing to a more robust BAC.
Expert Judgment: Involving experienced professionals in the estimation process can significantly improve the accuracy of the BAC. Their knowledge and past experiences can help identify potential risks and unforeseen costs.
Parametric Estimating: This technique uses statistical relationships between historical project data and project parameters (e.g., size, complexity) to estimate project costs. It's most effective for projects similar to past projects.
Chapter 2: Models Related to BAC
Several models utilize BAC as a fundamental element for project control and performance measurement. The most prominent is:
Earned Value Management (EVM): EVM is a project management technique that integrates scope, schedule, and cost to provide a comprehensive assessment of project performance. BAC is a key input in EVM calculations for metrics like Cost Performance Index (CPI), Schedule Performance Index (SPI), Cost Variance (CV), and Schedule Variance (SV). These metrics provide insights into project performance against the planned BAC.
Agile methodologies: While less reliant on a fixed BAC upfront, agile approaches still use budgeting and forecasting. The BAC might be considered a high-level target, but iterative sprints allow for continuous adjustment based on changing priorities and learnings.
Other models, like critical path method (CPM) and program evaluation and review technique (PERT) indirectly contribute to determining the schedule related factors that influence the BAC by providing an estimated timeline for the project.
Chapter 3: Software for BAC Management
Numerous software solutions facilitate BAC management and EVM calculations:
Microsoft Project: A widely used project management software that allows for detailed cost estimations, tracking, and reporting, including EVM calculations based on the defined BAC.
Primavera P6: A robust enterprise project management tool offering advanced scheduling, cost management, and reporting capabilities, making it ideal for large and complex projects with detailed BAC management needs.
Jira: While primarily known for agile software development, Jira can be integrated with plugins and add-ons to track costs and budgets, contributing to managing BAC within an agile context.
Various cloud-based project management tools: Tools like Asana, Monday.com, and Trello offer basic cost tracking features that can help monitor progress against a defined BAC, though they might lack the advanced features of dedicated project management software.
Chapter 4: Best Practices for BAC Management
Effective BAC management relies on several best practices:
Detailed Planning: A thorough and comprehensive project plan is essential. This includes a detailed WBS, realistic cost estimates, and a clearly defined scope.
Regular Monitoring and Control: Track project progress against the BAC frequently and proactively address any deviations.
Accurate Data Collection: Maintain accurate records of all project costs and actual work performed.
Regular Reporting: Provide regular reports to stakeholders showing project performance against the BAC, including relevant variances and potential issues.
Contingency Planning: Include a contingency reserve in the BAC to account for unforeseen risks and uncertainties.
Change Management: Establish a formal change management process to control changes in project scope and their impact on the BAC.
Chapter 5: Case Studies of BAC Application
Case Study 1: Construction Project: A large-scale construction project uses a detailed WBS and bottom-up estimating to determine a BAC of $50 million. Regular monitoring reveals cost overruns due to unforeseen ground conditions. The project manager uses EVM to assess the impact, implement corrective actions, and revise the BAC.
Case Study 2: Software Development Project: An agile software development team uses a high-level BAC as a target. Using iterative sprints, the team tracks progress against the budget and adjusts the remaining work based on velocity and new requirements. This demonstrates BAC adaptation in flexible project models.
Case Study 3: Marketing Campaign: A marketing campaign uses a top-down approach to establish a BAC. Tracking actual costs against the plan reveals under-spending due to successful cost-saving measures implemented during the campaign.
These case studies highlight how BAC is applied in various contexts and how its successful management contributes to overall project success. The use of EVM or other relevant methodologies is demonstrated, showcasing different approaches to tackling variations from the initially planned BAC.
