Connector
Connector
The chronological connection between two Activity Decision Flow Diagram objects. By default, it represents the flow of control in an Activity Decision Flow Diagram. However, a Connector can be defined as a Data Flow Only in conjunction with a Phi.
Task
Task (a rounded rectangle)
A Task object represents the lowest-level activity that a person or system can perform.
Phi
Phi
An Activity Decision Flow Diagram object that is an output from one activity and/or an input to the next activity. This object represents the data or product that is manipulated or produced during  the performance of a Process. The name “Phi” is derived from the Greek letter phi (F) because it is made up of the letter I (for input) superimposed over an O (for output).
Process
Process (a square)
A Process object represents a high-level grouping of activities that take place in a business process. A Process may contain Task objects or even other processes, called sub-processes, creating a hierarchy.
External Entity
External Entity (an oval)
An External Entity is outside the organization (customer, partner, supplier) that affects your organization's processes.
Decision
Decision (a diamond)
There are two forms of a Decision: Binary and Multiple.
Binary Decisions
A Decision that has two pre-defined Choices: Yes and No.
Multiple Decisions
  • Exclusive
  • Inclusive
  • Complex

 Choice (a small octagon)
At a Decision, a Choice must be made to determine the Task that will follow. Choice objects are the possible outcomes of a Decision.
Stop
Stop (a traffic stop sign)
A graphical marker, with no data attached to it, that shows that a path within the Process has ended. A process may have multiple paths, with some paths coming to an end while others continue.
Go To
Go To (a star)
Go To's that are shaped as stars indicate a shortcut for a Connector that would otherwise stretch over too great a distance in the diagram (would be hard to follow and distracting).
Annotation
Annotation (a sticky note)
Yellow notes to write comments on the Process Flow to further explain or define any aspect.
Annotation
Control Flow Only
One of two types of Process Flow, the other type is Data Flow. A situation where the flow of control between activities is not accompanied by the flow of Data. A Connector drawn with a solid line with no Data between activities represents Control Flow Only.
Control flow only
Control Flow and Data Flow
Specifies the chronological sequences of activities in a Process. A connector drawn with a solid line between activities represents Control Flow. If one or more Data is inserted between the activities, then the Control Flow is accompanied by Data Flow. Data Flow is a representation of the data or objects that are produced and transferred between activities. The Data that are inserted between activities are the graphical representation of Data Flow.
Data flow only
Data Flow Only
A situation where the flow of data between activities is not accompanied by the flow of control. A Connector drawn with a dotted line with a Phi between activities represents Data Flow Only. A Phi is required for Data Flow Only.
