Earned Value Analysis (EVA) is a method that allows the project manager to measure the amount of work actually performed on a project beyond the basic review of cost and schedule reports. EVA provides a method that permits the project to be measured by progress achieved.

Earned Value Analysis (EVA) can be used as an early warning system to provide a clear picture of the project's performance status with respect to budget and schedule. It can also show us whether the project is progressing well, poorly, or in danger, when the setup and feeding of the information is done on a regular basis.

In Cost Management, CPI is the Valuable term to Analyse the Efficiancy of the Project at any Particular time of Progress. CPI = EV / AC is nothing but the Ratio between the Actual Cost Vs the Budgeted Cost for the Project. If the CPI is less than 1 (project over budget - Loss) or greater than 1 (project under budget - Profit). The EV is simply Calculated by multiplying total Projet Budget multipled by % of Completion. In most cases , it gives bare value, since the Financial & Schedule Completion Percent is not same in majority of the Project.

Initially, I found the Earned Value Management (EVM) method complex, but it became familiar through reading. Many planners unknowingly implement its principles. Assigned the task by top management to introduce EVM to the Ahwaz urban railway project, the team took several steps. 1- Professionals attended training courses covering scope, time, and cost management for required stakeholders. 2- Due to the project's scale, specific work packages were designated as cost accounts for EVM tracking. 3- Crucially, communication was established with all stakeholders, ensuring engagement from contractor departments, consultants, and project owners. The belief in routine tracking as indispensable for achieving desired results was emphasized.

Es una herramienta para el control de proyectos, que integra variables de avance (según cronograma planificado) y costos (según presupuesto planificado); en función a ello, desde un punto de control incluso puede proyectar una tendencia de como sería el final del proyecto. Es una herramientas, que matemáticamente tiene funciones lineales, que es donde radican sus mayores discrepancias; pero termina siendo una ayuda potente para que si es necesario, revisar en mayor detalle ciertos puntos con otras herramientas.

To apply earned value management (EVM) to a construction project, it is necessary to clearly define the project's milestones and activities, obtain accurate and up-to-date data, and gain the commitment of all stakeholders. Additionally, it is important to involve stakeholders early on, track the project's progress regularly, and use EVM to make decisions.

In construction, aligning Integrated Risk Management with Earned Value Analysis (EVA) is crucial. For instance, consider a project where adverse weather can disrupt timelines. By assigning risk-adjusted values to weather-sensitive work packages, project managers gain a nuanced understanding of potential delays. Example: In a construction project involving outdoor tasks like foundation pouring, unpredictable weather poses a risk. Integrating risk management into EVA involves assigning adjusted values to these tasks, factoring in the likelihood and impact of adverse weather. This nuanced approach allows project teams to proactively adapt plans and implement contingencies, ensuring a more accurate representation of progress.

Actual EV value of the Project is nothing but the budget value for the Executed or Work Done Quantity. For Getting the EV value, we need to bufircate the Total Project Cost in to manageable Package cost and then Line Item wise Details on Each Package similar to BOQ Items. The EV can be Calculated Line Item Wise based on the inputs Given (i.e., Providing Work Done Quantity). These EV cost should be tracked with Actual Cost Incurred for the Project which is provided by CA / Accountant for the Organization. Normally Accounts Person is giving the Dump File of Actual Cost Incured for the Project should also bifurcated in to Package wise, Line Item wise further for better comparision.

La teoría dice que debemos definir líneas base (costo y tiempo para el EVA), en la práctica debemos llevar este análisis hasta el nivel de paquete, entendiendo así a la unidad mínima a la que le podamos asignar recursos (para costearlo) y tiempo (para definir una duración), esta ejercicio inicial cuando se finalice constituirá el plan o lo planeado (PV). Conforme se desarrolle el proyecto, podremos identificar "cuanto valor hemos generado" (EV) respecto del plan (PV) y con el feedback del equipo de costo, podremos saber lo que realmente hemos gastado hasta ese momento (AV). Con estos valores podremos obtener los KPIs más conocidos como son el SPI y CPI, no siendo los únicos de interés.

The Benefits of EVA is nothing but benefits of Cost sheet what we are prepared and updated on Monthly cycle. It clearly indicates on which package, Which Line Item is Exceed the Budget Value (EV Value). Even we can track Material / Labour / P&M / Consumable / CAPEX / OPEX Expenditures at Micro Level on Each Line Item in BOQ for getting better Result. It will Give the Awarness to the Project Manager to optimise the Resources, Evaluate Alternative / cost Effective Materials / Proposals to Reduce the Cost over Burden of the Negative Line Items. It allow to claim an Escalation / Price Variation of Materials / Labous if Contract Clause Permits.

Beneficios de usar el valor ganado en la construcción: - Mejora la precisión de la planificación y el pronóstico. - Mejora la comunicación y la colaboración. - Mejora la toma de decisiones. Beneficios específicos: - Mejora la eficiencia y la productividad. - Reduce el riesgo. - Mejora la satisfacción del cliente.

El EVA no es una herramienta financiera, tampoco es una herramienta holistica de todas las variables del proyecto. Pero sin duda es una herramienta que te dará una referencia de cómo está evolucionado el avance general de tu proyecto, no sólo en función de cuanto se está haciendo, sino también de cuanto estas gastando para ello. En la práctica es común encontrar referencias de valor para los kpis en funcion del avance del proyecto o del gasto del presupuesto. Con ello podremos activar preventivamente alguna medida de ser necesario.

1. **Early Issue Detection:** Identifies potential issues early, allowing prompt resolution. 2. **Comprehensive Assessment:** Integrates cost, schedule, and scope for a holistic project performance view. 3. **Objective Metrics:** Provides quantifiable metrics like CPI and SPI for objective performance evaluation. 4. **Efficient Resource Allocation:** Optimizes resource allocation by identifying areas of overruns. 5. **Improved Decision-Making:** Offers data-driven insights for informed decision-making. 6. **Clear Communication:** Facilitates clear communication with stakeholders through standardized metrics. 8. **Real-Time Monitoring:** Allows real-time monitoring of project progress. 9. **Performance Predictions

Tener al tope los kpis del EVA no significa que estas generando valor a tu cliente y que los interesados estan todos satisfechos. Lo único que podemos afirmar es que estas ejecutando correctamente tu plan y aquí, es donde se activa la divergencia teórica. "El plan es uno solo y siempre debe (sin lugar a duda) de estar actualizado" bajo esta idea el EVA te deberia dar el mejor reflejo de la salud de la evolucion de tu proyecto; sin embargo, sabemos que en la práctica has aspectos que se gestionan en verticales complementarias a un plan central, como la gestion de interesados, satisfaccion del cliente, gestión de riesgos y otros.

Some of the Challenges of Earned Value Analysis (EVA) in construction are: 1. **Complexity:** EVA can be complex, especially for large projects. 2. **Data Accuracy:** Relies on accurate and timely data; discrepancies can affect reliability. 3. **Assumption Sensitivity:** Changes in assumptions impact analysis accuracy. 4. **Adaptation to Agile Methods:** May be challenging to adapt to agile methodologies. 5. **Limited Predictive Power:** Less effective in dynamic project environments. 6. **Subjectivity in Metrics:** Interpretation of metrics can be subjective. 7. **Overemphasis on Metrics:** Risk of overemphasizing metrics without considering qualitative aspects.

Inaccurate Baseline Estimates: One of the most common challenges in EVM is inaccurate baseline estimates. This can happen when PMs fail to accurately estimate the scope, duration, and cost of a project during the planning phase. As a result, the earned value calculations may not accurately reflect the progress of the project, leading to misleading performance indicators. To overcome this challenge, PMs should invest more time and effort in accurately estimating the baseline, considering historical data, expert opinions, and thorough analysis of project requirements.

El valor ganado es una herramienta poderosa que puede ayudar a mejorar la gestión de proyectos de construcción. Sin embargo, hay algunos retos que pueden dificultar su uso efectivo, como la recopilación de datos precisos y actualizados, el compromiso de los interesados y el hecho de que no es una solución mágica. Para superar estos retos, es importante involucrar a los interesados desde el principio, establecer procesos claros para la recopilación de datos, formar a los empleados en el uso del EVM y utilizar el EVM para identificar problemas temprano.

Primero, debemos entender lo que no es, y así no esperaremos obtener esa informacion del EVA. Segundo, por la integración del costo, muchos piensa que el EVA es una herramienta de control financiero y hasta contable, lo cual es un error funesto. Tercero, hay umbrales para obtener buenos SPI a costa de sacrificar CPI menores a 1 (gastando más de la cuenta) con el fin de atender algun aspecto relevante del proyecto, será muy especifico al proyecto saber si esto es bueno o malo; en casos como estos es un reto para el EVA saber que información ofrecer.
