Permanent resources
Permanent resources are typically the people or equipment needed to carry out tasks. For example, a task to dig a foundation needs a digger and a driver. When a permanent resource has completed work on one task, it is available to work on another: permanent resources are not 'used up' by tasks.
Once you have created a permanent resource you can assign it to tasks.
You can edit the properties of a permanent resource by editing options on the Permanent Resource Properties dialog. To access help for each tab of the Permanent Resource Properties dialog, press F1 while viewing the tab.
