The PMO is used to maintain and provide a cadre of skilled and trained project professionals as needed under the:

A) Control tower model.

B) Cadre model.

C) Weather station model.

D) Resource pool model

D) Resource pool model

Explanation:

The Resource Pool is a set available to define project tasks. The resource pool can be assigned to only one project or task, or can be shared by several projects. A resource may be part of a separate resource list for multiple projects, or a single resource can be part of a common resource pool. Automation of project management facilitates the creation and use of resource pools. The project management software allows you to create custom project documentation for resource information that facilitates data and task management. The Resource Pool allows you to schedule sources for multiple projects. Because the information is integrated and accessible to all users, you can quickly identify contradictions between the tasks of an employee in different projects and see how their time is devoted to each project.
