In the world of project planning and scheduling, planned cost plays a crucial role in ensuring successful execution and keeping projects within budget. It represents the estimated cost of completing a project activity or task, set when the schedule becomes the official plan, or "baseline plan".
Understanding Planned Cost:
Think of planned cost as the budget allocated for a specific project element. It serves as a benchmark against which actual costs incurred during the project are compared. This comparison helps identify potential deviations from the planned budget, enabling timely intervention and corrective actions.
Setting Planned Cost:
Establishing accurate planned costs is essential for successful project management. This involves:

Scenario: You are managing a software development project with a planned cost of $100,000. The project is divided into three phases: design, development, and testing. Your initial estimates for each phase are:
After completing the design phase, you find that the actual cost incurred was $25,000.
Task:
**1. Cost Variance Calculation:** * **Cost Variance (CV) = Actual Cost - Planned Cost** * **CV = $25,000 - $20,000 = $5,000** The cost variance for the design phase is $5,000. This indicates a cost overrun. **2. Analyzing the Cost Variance:** Several reasons could have contributed to the cost overrun: * **Unexpected design complexity:** The design phase might have encountered more complex requirements than initially anticipated. * **Unforeseen resource needs:** Additional resources, such as specialized software or consultants, might have been required. * **Time constraints:** Time pressures might have led to increased labor costs. **3. Adjusting the Planned Cost:** Based on the cost overrun in the design phase, it's essential to adjust the planned cost for the remaining phases. Consider the following: * **Re-evaluate the estimates:** Revisit the estimates for the development and testing phases, factoring in the lessons learned from the design phase. * **Implement cost-saving measures:** Explore ways to reduce costs in the remaining phases, such as optimizing development processes or finding more cost-effective resources. * **Communicate with stakeholders:** Inform stakeholders about the cost overrun and the proposed adjustments to the planned cost. **Conclusion:** The cost variance in the design phase highlights the importance of regularly monitoring actual costs against planned costs. By analyzing the variance and adjusting future estimates, you can proactively manage project costs and increase the likelihood of delivering the project within budget.
Chapter 1: Techniques for Determining Planned Cost
This chapter delves into the various techniques employed to accurately estimate the planned cost of a project. Accurate estimation is crucial for effective project management and avoiding cost overruns. The techniques discussed will range from simple to complex, depending on the project's size and complexity.
1.1 Bottom-up Estimating: This approach involves breaking down the project into its smallest constituent tasks or work packages. Each task is individually costed based on resource requirements (labor, materials, equipment) and their respective rates. These individual costs are then aggregated to arrive at the total planned cost. This method is highly accurate but can be time-consuming for large projects.
1.2 Top-down Estimating: This is a more simplistic approach, often used in the early stages of a project when detailed information might be unavailable. The total project cost is estimated based on historical data from similar projects or expert judgment. This estimate is then proportionally allocated to different project phases or components. While quicker, it is less precise than bottom-up estimating.
1.3 Parametric Estimating: This technique utilizes statistical relationships between historical project data and key project parameters (e.g., square footage for construction, lines of code for software development). Regression analysis can be used to develop equations that predict cost based on these parameters. It offers a balance between accuracy and speed.
1.4 Analogous Estimating: This method relies on comparing the current project to similar past projects. The cost of the past project is adjusted based on differences in scope, complexity, and other relevant factors. It is a fast approach but relies heavily on the availability of comparable projects and the judgment of the estimator.
1.5 Three-Point Estimating: This technique reduces the uncertainty associated with single-point estimates by incorporating three different estimates: optimistic, pessimistic, and most likely. These estimates are then combined using a weighted average (e.g., PERT method) to arrive at a more realistic planned cost.
Chapter 2: Models for Planned Cost Management
Effective planned cost management requires appropriate models to track, analyze, and control costs throughout the project lifecycle. This chapter explores several key models.
2.1 Earned Value Management (EVM): EVM is a powerful technique that integrates scope, schedule, and cost to provide a comprehensive view of project performance. It uses metrics like Planned Value (PV), Earned Value (EV), and Actual Cost (AC) to calculate cost variance and schedule variance, providing insights into cost performance.
2.2 Cost Baseline: The cost baseline represents the approved planned cost of the project. It serves as the benchmark against which actual costs are compared. Any deviations from the baseline require investigation and corrective action.
2.3 Cost Control Chart: This visual tool graphically represents planned costs, actual costs, and budget variances over time. It allows for easy identification of trends and potential cost overruns.
Chapter 3: Software Tools for Planned Cost Management
Several software tools can assist in planning, tracking, and controlling project costs. This chapter reviews some popular options.
3.1 Microsoft Project: A widely used project management software that includes features for budgeting, cost tracking, and reporting.
3.2 Primavera P6: A powerful enterprise-level project management software, often used for large-scale projects, with advanced cost management capabilities.
3.3 Spreadsheet Software (Excel): While less sophisticated than dedicated project management software, spreadsheets can be used for basic cost tracking and analysis, especially for smaller projects.
3.4 Cloud-based Project Management Software (Asana, Trello, Monday.com): These tools offer collaborative features and cost tracking functionality, particularly useful for distributed teams.
