Earned Value Analogy: Project as a Tree
Fruit = Task Deliverable
Leaf = Task Event
Twig = Unplanned Task
Branch = Planned Task
Tree = Individual Project
Orchard = All Projects
Notes:
This diagram illustrates a tree structure as the metaphor for a project.
Most think of project management as being about managing tasks and the relationships (dependency, schedule) between them. When resources are not being accounted for or managed as part of the program or project, then task-orientation is sufficient.
However, advanced project management is more focused on the resources and their planning and utilization.
