Project Cost Management


  • Plan Cost Management
  • Estimate Costs
  • Determine Budget
  • Control Costs

Plan Cost Management

  • Established policies Procedures, and documentation for planning, managing, expending, and controlling project costs

Key Inputs

  • Project management Plan
  • Schedule Baseline
  • Project Charter

Tools and Techniques

  • Expert Judgement
  • Analytical Techniques
  • Planning Meetings

Key Outputs

  • Cost Management Plan

Estimate Costs

  • The process of developing an approximation of monetary resources needed to complete project activities. A

The accuracy of the estimates gets better the further into the project you are.

  • Accuracy ranges
    • Initiation Phase
      • -25% to +75%
    • Planning  Phase
      • -10% to +25%
    • User Testing Phase
      • -5% to +10%

Key Inputs

  • Cost Management Plan
  • Human Resource Plan
  • Scope Baseline
  • Project Schedule
  • Risk Register

Tools and Techniques

  • Expert Judgement
  • Analogous Estimating
  • Parametric Estimating
  • Three-point Estimating
  • Bottom-up Estimating
  • Reserve Analysis
  • Vendor Bid Analysis

Key Outputs

  • Activity Cost Estimates
    • Quantitative assessments of the probable costs required to complete the project work.
  • Basis of Estimates
    • additional necessary details that support the cost estimate

Determine Budget

  • The process of aggregating the estimated costs of individual activities of work packages to establish an authorized cost baseline.

Key Inputs

  • Activity Cost Estimating
  • Basis of Estimates
  • Scope Baseline
  • Project Schedule
  • Resource Calendar
  • Risk Register

Tools and Techniques

  • Cost Aggregation
  • Reserve Analysis

Control Costs

  • The process of monitoring the status of the project to update the project budget, and managing changes to the cost baseline.

Key inputs

  • Cost Management Plan
  • Work Performance Data

Tools and Techniques

  • Earned Value Managment (EVM)
  • Schedule Performance Index
  • Cost Performance Index
  • To-Complete Performance Index (TCPI)

Key Measurements

  • Planned Value (PV)
    • The Value of the work that was planned to be completed by a date
  • Budget At Completion (BAC)
    • Total PV for the Project
  • Earned Value (EV)
    • The value of work that was completed as of a date
  • Actual Cost
    • Actual cost incurred for accomplishing the work performed as of a date
  • Scheduled Variance (SV)
    • Earned Value (EV) – Planned Value (PV)
    • SV=EV-PV
  • Cost Variance (CV)
    • CV=EV-AC
  • Schedule Performance Index (SPI)
    • SPI=EV/PV
    • Ratio >1 indicates the project is performing better than planned
  • Cost Performance Index (CPI)
    • CPI=EV/AC
    • Ratio >1 indicates that is more value earned by spending money than planned.
  • Return on Investment (ROI)
    • ROI=Net profit/Investment

Key Outputs

  • Work Performance Measurements
  • Costs Forecasts
  • Change Requests
