Summary:
Some Organizations want visibility to the Projects created so that they do not work on the same Project that is worked upon by a different department. In this case we can make these changes in the Project leader permission type.

Resolution:
Log in with Administrator credentials.
Click on Administration in the Top Menu
In the User/Departments column at the left click on Permissions
Click on the Project Leader permission type assigned to the Project Leader.
Expand Projects
check off View for the options All Projects

Note:
If you want to also view data for All Projects, with out editing them then we can check off view for:
Assignments / Team
Expenses
Project Information
Rates
Roles
Task Information
