Limitations Of Using Earned Value Management System

By George Butler


IT executives continue to face challenges when it comes to project management. There being so many schemes that have been implemented, the earned value scheme continues to gain more popularity. This is due to the benefits the scheme gives to organizations compared to other software. The scheme has been in use for the last 30 years where its popularity continues to grow as the best flexible model that covers all the stages of a projects life-cycle. And here are the top secrets that organizations need to know about Earned Value Management system.

In any project the quality of work is a very important key. When using the earned value administration system the model does not take in to consideration the quality of work but rather concentrates on the success of the project.

For the methodology to successfully work for organizations, they should ensure that there is team work and good communication within the organization. Failure to have these requirements, the system will not work perfectly well. This is because the program involves gathering, processing and information dissemination of the project from the juniors to the stakeholders.

Organizations which use these systems help them reduce the work load since they assist them to handle only the critical issues. This ensures that the management only tackles the most crucial matters thus giving them time to focus on other activities.

The cost of purchasing the scheme is quite expensive that is why small organizations do not prefer using the scheme. Also the facts that the scheme works well for organizations with functional entities which work together limit some companies from using the model. Also implementation of the scheme requires a long term approach while some of the organizations require short term approach. This limits them from using the structure no matter the system being a good predictor for projects.

The metrics of the earned value structure of administration are very reliable when it comes to project performance prediction. The system achieves this by combining the project scope, schedule and cost as a three metric dimensions that collectively can be used to predict and measure the performance. These three metrics have proven to be accurate and realistic thus making the model be relied by practitioners.

As much as the use of the EVMS is highly recommended and help organization to predict the success of their projects, applying the system on a project that is in progress can have detrimental effects to the whole project. This can affect the organization, schedule, budget and the performance of the whole project.

The model takes earned value as the base line when predicting the values. However, the predictions may not be accurate at times. This is due to some of the foreseen risks which may cause some delays. Basing the assumption on the planned figures can land organizations in to troubles. On the other hand, the idea requires software to be used for it to accomplish its goals. The cost of purchasing this software is high and that is why most managers do not prefer using the system since they are not able to know exactly whether the project is in good shape or not thus limiting its use.
