Assignment in The Previous Weeks You Developed A Plan For Project Mana

In the previous weeks, you developed a plan for project managing acquisition projects. In Week 1, you discussed which tools would be most appropriate for managing cost, schedule, and technical performance. In Week 2, you evaluated the difference in managing a project if it is small in nature. In Week 3, you focused specifically on guidelines for acquisition projects. In Week 4, you incorporated cost methods and tools to assist you in project tracking and monitoring.

This week, you will be incorporating earned value management and how overall cost and schedule performance will be monitored and controlled.

Introduction

Effective project management is integral to the success of acquisition projects, especially for ensuring that objectives are met within budget and schedule constraints. This paper discusses the integration of Earned Value Management (EVM) into project monitoring and control, focusing on its application in various scenarios, and delineates the processes for tracking overall performance. An understanding of how to interpret variances and respond accordingly is vital for project managers to maintain project health and deliver value.

Earned Value Management System (EVMS)

Earned Value Management System (EVMS) is a systematic project management process that integrates scope, schedule, and cost to assess project performance and progress quantitatively. Implementing EVMS involves establishing baseline metrics for planned value (PV), earned value (EV), and actual cost (AC), along with relevant performance indices such as Schedule Performance Index (SPI) and Cost Performance Index (CPI), to evaluate project health at any given point (Fleming & Koppelman, 2016).

The core formulas used in EVA are:

  • Planned Value (PV): The budgeted cost assigned to scheduled work.
  • Earned Value (EV): The budgeted cost of work actually performed.
  • Actual Cost (AC): The actual expenditure for the work performed.
  • Schedule Performance Index (SPI):SPI = EV / PV
  • Cost Performance Index (CPI):CPI = EV / AC

These metrics facilitate the calculation of variances:

  • Schedule Variance (SV):SV = EV - PV
  • Cost Variance (CV):CV = EV - AC

Interpreting these formulas across different scenarios helps project managers understand project status and take corrective actions promptly.

Handling Different Project Scenarios with EVA

1. Behind Schedule and Over Budget

When a project is behind schedule and over budget, the calculations typically show negative variances and indices below 1. For example, suppose at a review point, the planned value (PV) is $100, while the earned value (EV) is $80, and the actual cost (AC) is $110. The variances and indices are:

  • SV = 80 - 100 = -20 (negative, indicating behind schedule)
  • CV = 80 - 110 = -30 (negative, indicating over budget)
  • SPI = 80 / 100 = 0.8 (less than 1, behind schedule)
  • CPI = 80 / 110 ≈ 0.73 (less than 1, over budget)

A sample graph would show the EV and PV diverging over time, with the EV lagging behind the PV, and AC exceeding the planned costs. To address this, project managers can use performance indices to forecast future performance using Budget at Completion (BAC) and Estimate at Completion (EAC), often calculated as:

  • EAC (typical):EAC = BAC / CPI

This forecast indicates the total expected cost given current performance. If nothing changes, the project will likely continue on this trajectory, requiring corrective measures.

2. Ahead of Schedule and On Budget

In this scenario, the variances are positive, and indices are above 1. For example, PV = $100, EV = $105, AC = $100. Calculations:

  • SV = 105 - 100 = 5 (ahead of schedule)
  • CV = 105 - 100 = 5 (under budget)
  • SPI = 105 / 100 = 1.05
  • CPI = 105 / 100 = 1.05

A sample graph would demonstrate EV surpassing PV, indicating earlier project completion, with actual costs below planned. Future performance estimates can be calculated similarly, with projections suggesting potential underruns if trends continue.

3. Behind Schedule and On Budget

Here, the project is on budget but lagging in schedule. Suppose PV = $100, EV = $80, AC = $95. The calculations are:

  • SV = 80 - 100 = -20 (behind schedule)
  • CV = 80 - 95 = -15 (slightly over budget, but close)
  • SPI = 80 / 100 = 0.8
  • CPI = 80 / 95 ≈ 0.84

Graphs here would show EV trailing PV, with costs remaining manageable but schedule delays evident. Managers may prioritize schedule acceleration techniques, such as crashing or fast-tracking, while monitoring costs closely.

4. Ahead of Schedule and Under Budget

Conversely, if EV is higher than PV and actual costs are low, say PV = $100, EV = $110, AC = $90, then:

  • SV = 110 - 100 = 10 (ahead of schedule)
  • CV = 110 - 90 = 20 (under budget)
  • SPI = 110 / 100 = 1.10
  • CPI = 110 / 90 ≈ 1.22

This indicates excellent project health, and management might consider resource reallocation or scope adjustments for further optimization.

Overall Cost and Schedule Performance Monitoring

Monitoring project progress involves continuous analysis of EV, PV, and AC at regular intervals, using dashboards, reports, and performance indices to track deviations. Metrics such as SPI and CPI enable quick assessments of schedule health and cost efficiency. Regular variance analysis, coupled with trend analysis, helps identify whether current performance is sustainable or requires intervention.

Reports and graphs, including integrated project dashboards, S-curves, and performance trend charts, provide visual representations of data, fostering proactive decision-making. To determine the cause of variances, project managers conduct root cause analyses, examining factors such as resource shortages, scope changes, or external influences.

Responding effectively involves adjusting schedules through schedule compression techniques (fast tracking or crashing), revisiting scope, or re-allocating resources. Contingency budgets are established during planning to mitigate risks and accommodate unforeseen costs or delays, serving as a buffer to maintain project objectives amidst uncertainties.

In implementing these strategies, initial planning and ongoing monitoring are essential, as is aligning project controls with organizational goals and stakeholder expectations.

Conclusion

Incorporating Earned Value Management into project control provides an objective, data-driven approach for monitoring and managing project performance. Understanding how to interpret variances and indices allows project managers to make informed decisions and maintain control over project scope, schedule, and costs. Effectively responding to deviations through schedule compression, scope adjustments, and contingency planning ensures that project outcomes align with organizational objectives, ultimately leading to project success.
