Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
An activity is a generic term for work that a company performs. It can be atomic or compound. Task A task represents a single unit of work that is not or cannot be broken down to a further level of business process detail. It is referred to as an atomic activity.

PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F).. The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project.
In context, project activities should support project task breakdown (also known as work breakdown structure), task allocation, inventory across projects, and concurrent access to task databases. Service activities pertain to client and internal company-services provision, including customer relationship management and knowledge management.
A Gantt chart is a type of bar chart [4] [5] that illustrates a project schedule. [6] This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. [4] [7] The width of the horizontal bars in the graph shows the duration of each activity.
A Work breakdown structure element may be a product, data, a service, or any combination. WBS also provides the necessary framework for detailed cost estimating and control along with providing guidance for schedule development and control. Work package is a subset of a project that can be assigned to a specific party for execution. Because of ...
The project schedule is a calendar that links the tasks to be done with the resources that will do them. It is the core of the project plan used to show the organization how the work will be done, commit people to the project, determine resource needs, and used as a kind of checklist to make sure that every task necessary is performed.
