Process Diagrams Learning Objectives • Understand the background and foundation of the process diagrams covered in the remaining lectures of this unit. 2

Process Diagrams Topics • Key process aspects that may require analysis and diagraming • Types of process diagrams 3

So Many to Choose From • Several kinds of process diagrams exist: – ISO 5807 Flow Charting – Yourdon (including Yourdon code, and Yourdon-De. Marco) – Gane-Sarson – Unified Modeling Language (UML) – Entity Relationship (E-R) diagram • They differ in notation and in the process aspects covered. 4

Process Features • • Context Process steps Data/information flow Data/information content Data/information transformation Step sequence, control, and status Who or what performs the process steps 5

Methods for Diagramming Processes Process Aspects ISO 5807 Context Process steps X Data flow steps X Information content Yourdon data flow Gane. Sarson UML X X X E-R diagram X X text X X Data transformation X Flow control and state X text X Roles involved X X Table 3. 1 Methods for Diagramming Processes 6

Recommended diagrams for health care facility workflow • Context • Data Flow • Process steps – Information content – Information transformation • Step sequence, control and status • Roles (who or what) performs the steps 7

Typical Workflow Diagramming Scenario • Need to diagram the process as it is • Context diagram to capture: – The whole – High-level data flow so that necessary data exchange is documented • ISO 5807 Flowchart to capture: – Process steps – Sequence and control of steps – Roles performing steps Note: the Public Health Institute’s Business Process Analysis and Redesign program is to improve the performance of the US public health system. 8

Process Diagrams Summary Lecture a • Understand key process aspects that may need to be diagramed • Suggest a diagram type for a given process aspect to be represented 9
