What is an activity-on-node diagram and how is it used in project management?
An activity-on-node diagram is a visual representation of project tasks and their dependencies. It is used in project management to show the sequence of activities and their relationships, helping to plan and schedule tasks efficiently.
What is the difference between activity diagram and sequence diagram?
Activity diagram shows the work flow from start point to the end point detailing many decision points. Sequence shows detail flow of specific use case and it also shows interaction between actors, system and system components
How state Diagram are different from the Activity Diagram?
They are not as they both have the same features it just provides a better understanding when using one diagram in conjunction with the other. State machine diagram shows how state of some object or system could change, so transitions on the diagram are from one state to another state. Activity diagram shows set of actions and how one action could lead to another. In simple cases these diagrams might look like reverse of each other but in practice you need to select whether the diagram is about discrete number of states of some object or is it about organization of actions and activities possibly related to many different objects.
What is the purpose of an activity diagram?
The purpose of the activity diagram is to model the procedural flow of actions that are part of a larger activity. In projects in which use cases are present, activity diagrams can model a specific use case at a more detailed level. However, activity diagrams can be used independently of use cases for modeling a business-level function, such as buying a concert ticket or registering for a college class. Activity diagrams can also be used to model system-level functions, such as how a ticket reservation data mart populates a corporate sales system's data warehouse. Because it models procedural flow, the activity diagram focuses on the action sequence of execution and the conditions that trigger or guard those actions. The activity diagram is also focused only on the activity's internal actions and not on the actions that call the activity in their process flow or that trigger the activity according to some event (e.g., it's 12:30 on April 13th , and Green Day tickets are now on sale for the group's Copyright Rational Software 2003 http://www.therationaledge.com/content/sep_03/f_umlbasics_db.jspsummer tour). Although UML sequence diagrams can protray the same information as activity diagrams, I personally find activity diagrams best for modeling business-level functions. This is because activity diagrams show all potential sequence flows in an activity, whereas a sequence diagram typically shows only one flow of an activity. In addition, business managers and business process personnel seem to prefer activity diagrams over sequence diagrams -- an activity diagram is less "techie" in appearance, and therefore less intimidating to business people. Besides, business managers are used to seeing flow diagrams, so the "look" of an activity diagram is familiar.
