Earned Value Analysis For Beginners

The Project Management Institute define Earned Value Analysis (EVA) as a fundamental project management technique that is a vital tool in ensuring successful project outcomes. Earned Value Analysis is used to measure and evaluate the performance of projects and helps in comparing the planned work with what has been achieved, both in terms of schedule and cost. EVA provides objective metrics to assess project progress, predict completion dates, and identify variances from the original plan.

By analysing key EVA terms such as Planned Value (PV), Earned Value (EV), and Actual Cost (AC), construction professionals can gain valuable insights into project management, enabling better decision-making and more successful project outcomes.


What is Earned Value Analysis in Construction?

Earned Value Analysis (EVA) in construction is a powerful project management methodology used to monitor and control construction projects. It involves the systematic assessment of a project's progress by comparing planned work (Planned Value or PV) with actual work completed (Earned Value or EV) and the associated costs (Actual Cost or AC). These three metrics are three of the most important Earned Value terms, read more about them here.

EVA helps construction professionals track project performance, identify deviations from the schedule and budget, and make informed decisions to keep construction projects on track. It is a critical tool for ensuring that construction projects are completed efficiently, within budget, and on time.

How is Earned Value Analysis used in Project Management?

Earned Value Analysis (EVA) is a valuable project management technique that plays a critical role in assessing and controlling project performance. EVA seamlessly integrates cost, schedule, and scope data, offering project managers a comprehensive and real-time view of their project's overall health. 

The process begins with the creation of a project baseline, encompassing planned schedules and budgets. Next, work measurement techniques are employed to track and measure the actual work completed, often represented in terms of physical units or a percentage of completion. 

EVA introduces key metrics such as Planned Value (PV), Earned Value (EV), and Actual Cost (AC) to quantitatively evaluate project performance. By comparing EV to PV, project managers can determine whether the project is ahead or behind schedule (Schedule Variance) and if it's under or over budget (Cost Variance).

 Moreover, EVA provides a robust foundation for forecasting future project performance, enabling informed decision-making and the proactive management of projects to keep them on course. Find out more about how Project Managers can use Earned Value Metrics to answer key questions here.

What are some vital EVA components and metrics you need to know?

To effectively utilise Earned Value Analysis (EVA) in project management, it's essential to grasp several key terms. Find out more about essential earned value definitions here. 

These terms include:

  • Planned Value (PV): Also known as Budgeted Cost of Work Scheduled (BCWS), PV represents the planned budget for work to be completed within a specific time frame. It serves as the baseline for project performance measurement. 
  • Earned Value (EV): EV, or Budgeted Cost of Work Performed (BCWP), measures the value of work actually completed at a given point in the project. It provides an objective assessment of project progress.
  • Schedule Variance (SV): SV quantifies whether the project is ahead or behind schedule by comparing EV to PV. A positive SV indicates progress ahead of schedule, while a negative SV suggests delays. 
  • Cost Variance (CV): CV assesses whether the project is under or over budget by comparing EV to AC. A positive CV indicates cost savings, while a negative CV suggests cost overruns. 
  • Schedule Performance Index (SPI): SPI measures the efficiency of schedule utilisation by dividing EV by PV. SPI values greater than 1 indicate efficient progress, while values less than 1 suggest schedule inefficiencies.
  • Cost Performance Index (CPI): CPI assesses cost efficiency by dividing EV by AC. CPI values greater than 1 indicate cost-effective performance, while values less than 1 suggest cost inefficiencies. 
  • Actual Cost (AC): AC, or Actual Cost of Work Performed (ACWP), reflects the actual expenditures incurred for work completed during a specific period. It represents the true cost of project activities.

Why is Effective Earned Value Analysis Important in Construction

Earned Value Analysis (EVA) is of paramount importance in construction for several reasons:

  • Effective Project Monitoring: EVA enables construction professionals to closely monitor project progress, identify deviations from the original plan, and take corrective actions promptly. This proactive approach minimizes delays and cost overruns.
  • Accurate Cost Control: By comparing actual costs (AC) with earned value (EV), EVA allows for precise cost control. It helps construction teams manage their budgets effectively and avoid unexpected financial challenges.
  • Objective Performance Measurement: EVA provides objective metrics to assess project performance. It eliminates subjectivity and provides a clear, data-driven view of whether a project is on track, behind schedule, or over budget.
  • Timely Decision-Making: Construction projects involve numerous stakeholders and dependencies. EVA's ability to predict project completion dates and identify issues in real-time enables project managers to make informed decisions promptly, ensuring project success.

In the construction industry, where time and budget constraints are critical, EVA serves as an indispensable tool for achieving project goals, maintaining profitability, and delivering high-quality construction projects. Want to test your knowledge? Take our Earned Value Analysis Quiz here.

How to use Earned Value Analysis to determine cost thresholds 

Establishing cost thresholds through EVA involves several critical steps. Firstly, it's essential to define acceptable cost variance limits based on the unique constraints and objectives of the project. Once these limits are set, the project manager calculates Planned Value (PV) and Earned Value (EV) for the project. These calculations lay the groundwork for monitoring and comparing the Actual Cost (AC) with EV to derive the Cost Variance (CV). The CV serves as a key indicator, and project managers use this value to set the cost threshold, signalling the acceptable margin for deviations from the budget. Regular monitoring and assessment of the project's cost performance against this threshold are imperative, prompting necessary corrective actions when CV breaches the established limit.

How to use Earned Value Analysis to Forecast Costs

EVA is a really great tool for forecasting project costs. To harness this capability, project managers follow a systematic approach. The process commences with the calculation of Planned Value (PV) and Earned Value (EV), which provide insight into the project's current cost performance. The Cost Performance Index (CPI), calculated as the ratio of EV to AC, offers a precise measure of cost efficiency. Project Managers then use the CPI to project future costs. For instance, if the CPI is 0.85, it indicates that for every £1 of planned work, £0.85 is being spent. This projected cost efficiency is multiplied by the remaining planned work, enabling project managers to forecast future costs effectively.

Armed with this forecasting data, project managers can anticipate whether the project will stay within budget or potentially incur cost overruns.

How to use Earned Value Analysis to Forecast Performance

Forecasting project performance is a crucial aspect of project management, and EVA can be instrumental in this regard. The process involves the calculation of Planned Value (PV) and Earned Value (EV) to ascertain the project's current performance status. From these metrics, Project Managers derive two vital indices: the Schedule Performance Index (SPI), calculated as EV divided by PV, and the Cost Performance Index (CPI), calculated as EV divided by AC. SPI and CPI offer quantitative insights into schedule and cost performance, respectively. To forecast future performance, Project Managers analyse these indices, noting trends and patterns.

An SPI of 1 indicates on-schedule performance, while a CPI of 1 signifies on-budget performance. Project Managers can extrapolate these trends to anticipate whether the project will meet its schedule and budget objectives.

How to use Earned Value Analysis to conduct schedule forecasting  

Project Managers can leverage EVA to conduct schedule forecasting efficiently. The process begins with the calculation of Planned Value (PV) and Earned Value (EV) for the project. These metrics serve as the foundation for computing the Schedule Performance Index (SPI), which quantifies schedule efficiency. By analysing SPI trends, project managers can predict future schedule performance. If the SPI consistently remains below 1, it suggests schedule delays. Project Managers can extrapolate this trend to estimate the project's likely completion date, facilitating proactive adjustments to mitigate schedule risks.

How to use Earned Value Analysis to produce time-phased budgets

EVA aids in the creation of time-phased budgets, a crucial aspect of project financial management. This process involves several key steps. Project Managers start by breaking down the project into manageable work packages or activities. For each of these components, budgets are assigned based on the project schedule, ensuring that financial resources are allocated appropriately over time. Throughout the project's lifecycle, Project Managers continuously track expenditures for each activity, ensuring that actual costs align with the time-phased budget. This alignment between actual costs (AC) and the time-phased budget provides Project Managers with precise insights into financial performance over time, enabling them to take corrective actions when necessary.

What is the risk of using Excel to calculate Earned Value Analysis?

While Excel is a versatile tool, it presents certain challenges when used for Earned Value Analysis on construction projects in particular. One of the primary limitations is the lack of sophisticated automation capabilities found in dedicated EVA software. As a result, Excel-based EVA often involves significant manual data entry and calculations, which can be error-prone and time-consuming. Additionally, Excel may struggle to handle the complexity of large-scale projects with numerous activities, potentially leading to unwieldy and confusing spreadsheets which can be difficult for team members to understand and draw accurate conclusions from. Additionally, if multiple team members are training to collaborate on a single Excel sheet maintaining data integrity and consistency can also be challenging. Moreover, Excel lacks the advanced reporting and visualisation tools necessary for in-depth project analysis which is most effective when conducted in real time as proactive project decisions can be made. Therefore, transitioning to specialised project management software designed for EVA can overcome these challenges and enhance the accuracy and efficiency of EVA implementation.
