Certainly! Here’s a **Traditional EVM Calculation** example for a Waterfall project, including a cost control plan, CPI, and SPI calculations. --- ## **Cost Control Plan for a Waterfall Project Using Earned Value Management (EVM)** ### **Project Overview** - **Project:** New Website Development - **Duration:** 4 months (16 weeks) - **Total Budget (BAC):** $100,000 --- ### **Planned Value (PV) / Budgeted Cost of Work Scheduled (BCWS)** - **At Week 8 (Midpoint):** - Planned % Complete: 50% - PV = 50% × $100,000 = **$50,000** --- ### **Earned Value (EV) / Budgeted Cost of Work Performed (BCWP)** - **Actual % Complete (as measured by deliverables):** 40% - EV = 40% × $100,000 = **$40,000** --- ### **Actual Cost (AC) / Actual Cost of Work Performed (ACWP)** - **Costs incurred after 8 weeks:** **$55,000** --- ### **EVM Calculations** #### **Cost Performance Index (CPI)** \[ CPI = \frac{EV}{AC} = \frac{\$40,000}{\$55,000} = 0.73 \] ##### *Interpretation:* - CPI < 1.0: The project is over budget (getting only $0.73 value per $1 spent). --- #### **Schedule Performance Index (SPI)** \[ SPI = \frac{EV}{PV} = \frac{\$40,000}{\$50,000} = 0.80 \] ##### *Interpretation:* - SPI < 1.0: The project is behind schedule (only 80% of planned progress achieved). --- ## **Cost Control Actions** ### **1. Variance Analysis** - **Cost Variance (CV):** EV - AC = $40,000 - $55,000 = **-$15,000** (over budget) - **Schedule Variance (SV):** EV - PV = $40,000 - $50,000 = **-$10,000** (behind schedule) ### **2. Forecasting** - **Estimate at Completion (EAC):** \[ EAC = \frac{BAC}{CPI} = \frac{\$100,000}{0.73} \approx \$136,986 \] - **Estimate to Complete (ETC):** \[ ETC = EAC - AC = \$136,986 - \$55,000 = \$81,986 \] ### **3. Corrective Actions** - **Root Cause Analysis:** Analyze why costs are higher and schedule is behind (e.g., resource efficiency, scope creep). - **Re-allocate Resources:** Assign additional resources to critical tasks. - **Cost Monitoring:** Review and approve expenditures more strictly. - **Scope Review:** Assess for possible reductions or re-prioritization. - **Schedule Compression:** Fast track or crash tasks where possible. ### **4. Ongoing Monitoring** - **Weekly EVM Tracking:** Continue to track PV, EV, AC, CPI, and SPI. - **Reporting:** Regular status reports to stakeholders. --- ## **Summary Table** | Metric | Formula | Value | Interpretation | |--------|---------|-------|---------------| | PV | Planned % x BAC | $50,000 | Planned value at week 8 | | EV | Actual % x BAC | $40,000 | Work actually accomplished | | AC | Actual cost to date | $55,000 | Money spent so far | | CPI | EV / AC | 0.73 | Over budget | | SPI | EV / PV | 0.80 | Behind schedule | | EAC | BAC / CPI | $136,986 | Projected final cost | --- ## **Conclusion** Using EVM, you can objectively measure cost and schedule performance, forecast outcomes, and take action to bring the project back on track. Regular monitoring of CPI and SPI, with prompt corrective actions, ensures the project remains under control. --- **If you need an Agile burn-up chart example instead, let me know!**
