Global Utilization (via Reporting) should count all actual hours on projects, including time logged on the Project, on Tasks or on Issues.
As resource managers look at the Global Utilization the Actual Hours reported is not counting all hours on projects - only hours logged on Tasks.
The purpose of Global Utilization should be to look at what was budgeted and planned and the total sum of actual hours on projects - not just those hours planned and logged on tasks. Commonly we have people work on projects where tasks in a workflow were not planned, or support projects from a strategic level. Users log time on projects, tasks and issues, and those hours should all be the calculated sum of Total Actual Hours on the project. From our research, Global Utilization is the only area to visualize the Budgeted Hours, Planned Hours and Actual Hours for groupings (programs) of projects. Project Utilization does include all actual hours, but we need to visualize many projects grouped in a Program and the total Budgeted, Planned and Actual hours.
