What are the benefits of using a Master Project file?

Creating a master project and subprojects lets you break down a large project and delegate its parts to the necessary people. In project management terms, assigning subprojects in this manner gives responsibility to those who do the work and matches authority with accountability. In Project terms, creating subprojects in a master project helps project managers gain access to, and control over, their parts of the schedule.

What information do I need about master project and subprojects files?

1. When you insert a subproject, a small specific icon distinguishes it from summary tasks that are part of the master project.

2. In the master project, subprojects appear as summary tasks that you can easily arrange in an outline.

3. Click the collapsed sign next to a subproject to expand that subproject's tasks for viewing/editing.

4. Each subproject represents a different phase or another functional group in the main project.

5. When you insert a subproject into the master project, the two projects are linked and you can view all the information in the subproject from the master project.

6. When you update a subproject from the master project, it is updated in its source file as well. If you just must combine files to create a report or print a view of combined-project information, you can also consolidate them temporarily in a view.

What features are allowed using subprojects?

  • Subproject file can contain another subproject file
  • Edit any fields from subprojects
  • Insert /delete tasks
  • Sort
  • Filter
  • Generate reports
  • Show Critical Path
  • Set /view baseline

Note: Any formatting changes you have applied to summary tasks or Gantt bars in a subproject does not appear in the master project. Formatting information is stored in each file and must be applied separately to the master project.

Does the Subproject’s Wbs reflect the WBS numbering flow in the master or does the Subproject retain its Wbs numbering?

The subproject will retain the WBS numbering. Only the Summary Subproject Task will have a calculated WBS based on his position in Master Project.

How resources are affected when you upload multiple subprojects in a Master Project?

After you consolidate files into a master project file, the tasks from subprojects files remain separate, resources are combined from all subprojects.

You can change resource information in the master project and the changes will be replicated in the subproject's source file.

You can view all resources in the master project and subprojects together in the Resource Sheet view, the resource can be edited /assigned.

If the same resources are used in multiple subprojects, you see the resource names just once because the resources are combined. However, it is recommended to use organization Resource Pool, then assign the resources in different subprojects.

Keep in mind that if you use the same resource in multiple projects, in Master Resource Sheet will appear one resource. If that resource uses different Std rate values in the subproject source file, the Master Project file will calculate an average value based on std rate value and cost per use.
