Process Mapping Learning Objectives • Read and interpret UML class, activity, and state diagrams 2

Process Mapping Topics - Lecture f • Purpose, symbols, and conventions for UML – Class, – Activity and – State machine diagram • Reading and interpreting the diagrams 3

Methods for Diagramming Processes Table 3. 5 Methods for Diagramming Processes. Nahm, M. , 2012. 4

Background • Developed by the Object Management Group (OMG) • First version, UML 1 released in 1997 • Created to overcome incompatibility of different notations for software modeling – i. e. , For software design and development, NOT workflow or process representation. • Adapts and incorporates pre-existing notations: – Flowcharts, Yourdon, Gane-Sarson, Entity- relationship diagrams and ISO 5807. 5

Use • Developed for visual modeling in software development • Later to automate software development • 13 different diagrams for representing aspects of computer software – Functionality, data content, and data movement – Not physical process steps • Many IT professionals are trained in UML • Workflow analysts may encounter UML diagrams 6

UML 2. 0 Diagrams Covered • Structure Diagrams – Class Diagram • Behavior Diagrams – Activity Diagram – State Machine Diagram • Interaction Diagrams 7

Class Diagram • Model of the information stored in a system • Analogous to the E-R diagram 8

Class Diagram Example 9

Class Diagram Notation • Classes are shown by boxes • Associations are shown by lines • Cardinality and modality are shown by numbers on the lines 10

Class Diagram - Larger View 11

Activity Diagram • Similar to a flowchart • Shows movement • Uses fewer symbols than flowcharts 12

Activity Diagram Symbols • Activities are shown by a long rectangle with rounded corners • Motion and direction are shown by lines with arrow heads • Branch points are shown by either diamonds or heavy horizontal lines • • • Symbols that have a meaning Start of a process is shown by a solid circle End of a process is shown by a solid circle concentric with a “no fill” circle 13

Activity Diagram Example Patient calls for appointment Receptionist answers Scheduled Office visit occurs 14

State Diagram • Shows the different “statuses” allowed • Valid transitions from state to state 15

State Diagram Symbols • Rectangles that show the states • Lines and arrows that show valid transitions from state to state 16

State Diagram Example open tentative scheduled arrived missed complete 17

Maintenance • UML is an international standard and is maintained by the OMG • The standard is freely available from the OMG web site 18

Process Mapping Lecture f - Summary • Purpose, symbols, and conventions for UML – Class, – Activity and – State machine diagram • Reading and interpreting the diagrams 19
