The use of the term enterprise project plan was intended to emphasis that the project itself was on a large scale and very complex. While this is still true, the software to conduct the enterprise projects has found other uses.
More and more managers as now using programs designed for use with an enterprise project on a vastly smaller scale. What was noticed is that this type of programming included more details that had been previously left out of those intended for a smaller scale project.
Because of the popularity of the enterprise project plan programs, the newer software that has hit the market are now compatible to handle any size project no matter how large or small. This allows for any project manager of any size company to use the same program for their projects.
There are some managers that still prefer to use the enterprise project programs for their business ventures. Many of them do it because of the comfort level they have with their existing program. This is similar to the employees that resist change and the need for a change management plan within an organization.
Another similarity the enterprise project programs have with the newer software program being developed for project planning is they both bring all of the organization to running the project into one centralized location. This allows for a clearer organization of the project to be carried out throughput the entire production run of the deliverable.
By only having to possess just one type of project planning the program, the ones designated for only enterprise project plans are becoming obsolete. This allows for an organization to only invest in one software program for their company to use. It also reduces the amount of training needed for the personnel to be effeicent with it when preparing projects for the creation of a revenue stream.
While the name enterprise project program is still very popular, you no longer have to use one when your company has a large and complex project to complete.
