Some of the main benefits of using the implementation projects within Functional Setup Manager are:
Implementation Project helps in assigning responsibility of managing setup data to a broad group of users. You can assign tasks to different users who are responsible for entering and validating setup data for different functional areas of the offering.
Implementation Project helps you to monitor progress of the setup tasks. You can track the status and completion percentage of each task and view the dependencies and prerequisites among tasks. Implementation Project does not give you the flexibility to set up different functional areas of the offering at different times, as this is determined by the configuration package that you select for your implementation. Implementation Project does not help you to use the manage setup data entry in bulk option, as this is a separate feature that allows you to import and export setup data across instances using spreadsheets.
