Quais são as vantagens e desvantagens de usar a análise de valor agregado em relação a outros métodos?

Earned Value Analysis (EVA) is a comprehensive approach that enables project managers to assess project performance by comparing planned value, actual cost, and earned value. By analyzing metrics like SV, CV, SPI, and CPI, EVA provides insights into schedule adherence and cost control. Moreover, EVA's calculations of EAC, ETC, and VAC offer valuable projections for the project's future trajectory and overall success. It is a robust tool for effective project monitoring, decision-making, and forecasting.

Earned Value Analysis (EVA) integrates cost, schedule, and scope for comprehensive project insights. Advantages include performance measurement and early issue detection. However, its complexity and resource intensity can be drawbacks, making it less suitable for smaller projects. Project managers should consider these factors when opting for EVA over simpler methods.

Essas métricas ajudam a analisar e comparar o custo orçado e real de um projeto em um determinado ponto no tempo. O EVA utiliza essas comparações para calcular variações de programação e custo, indicando se um projeto está adiantado, atrasado ou fora do orçamento. Além disso, fornece índices de desempenho de cronograma e custo para avaliar a eficiência do projeto. O EVA também projeta o custo total através da Estimativa na Conclusão (EAC), estima o custo restante, e calcula a variação entre o orçamento original e o custo final, além de determinar o desempenho necessário para concluir o projeto dentro do orçamento.

Earned Value Analysis (EVA) offers clear advantages like tracking project performance comprehensively and predicting future trends accurately. It covers all 3 constraints under one umbrella - cost, schedule, and scope, providing a holistic view. However, EVA can be complex to implement and requires accurate data inputs, making it resource-intensive. It may not factor in the unforeseen challenges. Additionally, it may not suit all project types, especially those with dynamic requirements. Evaluating EVA's pros and cons against project needs is crucial for effective performance measurement.

Understanding the progress measurement system and how it impacts EV and productivity related measurements, calculations, reporting actuals and forecasting future trends is important. Is the progress measurement system frontend, backend or a balanced loaded measurement process?

The EVA helps the project managers track project performances using KPIs like SPI,SV, CPI,CV, etc and predict future trends. It enables project managers to systematically measure project performance against the project baseline.

EVA stands out as a valuable project management tool due to its ability to offer a holistic and unbiased assessment of project performance, incorporating time, cost, and scope. Its proactive nature allows for early issue identification and informed decision-making. The use of standardized metrics and visual representations enhances communication with stakeholders, promoting transparency and understanding. With its ability to evaluate alternatives and assess risks, EVA aids in effective project planning and provides reliable projections for completion time and cost.

The advantage of using Earned Value Management (EVM) lies in its ability to provide early warnings of deviations. As a rule of thumb, if a project has progressed more than 25% and the Cost Performance Index (CPI) is below 0.8, it is likely that the project will not meet its cost baseline. Another advantage is that since the work is measured in monetary terms, the key three figures can be aggregated at the program and portfolio levels.

There are many advantages: -The SPI or SV suggests the performance of the project compared to the schedule baseline -The CPI or CV suggests the performance of the project compared to the cost baseline -It compares the actual status to the scope plan -It provides an alert if there is any scope creep -It provides an alert if any issues are hindering the progress etc

Counting the chips and or calculating the earned value is not truly accurate especially when determining what to include and or not to include in the project % complete calculations……….

Earned Value Management faces challenges in addressing modern project management indicators: - It lacks the measurement of key Lean indicators such as Work in Progress (WIP), Lead Time, Throughput, and deployment frequency, which are crucial for optimizing processes and improving efficiency. - EVM operates on a push system rather than embracing the pull system principles. It should postpone expenses/costs at the same time anticipate benefits/revenue. - The methodology does not identify or manage bottlenecks, lacking a system-wide and holistic view. This can lead to inefficiencies - Towards the project's conclusion, cumulative effects can distort the Schedule Performance Index (SPI), giving an inaccurate picture of efficiency.

While EVA offers valuable insights, it is not without limitations. Data accuracy and reliability are crucial for meaningful analysis, and the complexity of calculations can be a barrier. Regular updates are necessary to maintain relevance, and understanding its assumptions and limitations is essential to avoid misinterpretation. Additionally, the narrow focus on time and cost may overlook other significant aspects of project value.

EVA is time consuming and resource hungry to set up and manage. You also have to have a good understanding of the methodology and clear sponsorship. It also only works at project level. For these reasons I would only use EVA where the scale and complexity of the scope makes it worthwhile, where there is clear support and understanding of its value and the benefits of applying it outweigh the costs. And never roll the metrics up across a program or portfolio, the outputs are meaningless! It is a great tool for effective project management in the right circumstances; too many times it is applied as a comfort blanket and not applied well, and sometimes in an incomplete form.

Like any other analysis process, the EVA too has got some limitations. The major one is, it computes the KPIs, viz SV, CV,SPI etc at a cumulative level after each period, which may depict an inaccurate picture of the actual status of the project.

Traditional EVM can be less effective in accurately measuring schedule performance, particularly in complex projects. It also assumes a linear progress of work, which might not always be the case. ESM (Earned Schedule Management) enhances EVM by offering more accurate schedule performance measurements, providing realistic project completion time estimates. Meanwhile, EDM (Earned Duration Management) integrates the strengths of both EVM and ESM, combining cost and time management for a more comprehensive project performance overview. Intrigued? Dive deeper into ESM and EDM for a richer understanding of advanced project management techniques.

While EVA has its challenges and considerations, it remains a widely recognized and effective method for monitoring and controlling project performance, enabling project managers to make data-driven decisions and take proactive measures to keep projects on track.

The accuracy of the EVA calculations largely depends on the precision of the planned value. Thorough analysis and meticulous effort are required while computing the estimates for baseline viz the planned value. A sound knowledge of all estimation techniques and their applications is essential.

In my personal experience, I've implemented EVA keeping into account the “Enterprise Environmental Factors” (types of Projects managed by the enterprise, budget, type of contract…); this has always helped in: • defining how to be effective in identifying the right level of control. • tailoring the effort to be spent in EVA. • how to be detailed in the “data” collection and allocation (keeping in mind the quality of the data to be considered as input). Given the context above, I consider SPI and CPI extremely effective “signals” to drive my decisions to go in deeper analysis, in understanding the root causes of the variances and as consequence to suggest me the corrective actions to take.

Earned Value Analysis (EVA) offers insight into project performance by integrating scope, schedule, and cost metrics. In renewable energy projects like offshore wind power, EVA tracks progress against milestones, aiding in timely decision-making. However, it can be complex and requires accurate data, posing challenges in dynamic environments like battery energy storage system manufacturing, where unforeseen changes may affect projections. Despite its limitations, EVA remains valuable for holistic project monitoring and control.

EVA is a good measure to gauge Project progress. The methodology I have implemented on some Projects is to assign the value to each package or task with similar weights as they have in the Project Budget and recalibrate everything as and when actual costs/resources are known. This works wonders for LSTK packages. Supply or Service packages need to be coupled with stringent progress measurement norms to make it work effectively. EVA generally is a good metric if the Value Assignment is reasonable and realistic.
