  1. Component 10 – Fundamentals of Health Workflow Process Analysis and Redesign Unit 3-1 – Interpreting and Creating Process Diagrams: Introduction This material was developed by Duke University, funded by the Department of Health and Human Services, Office of the National Coordinator for Health Information Technology under Award Number IU24OC000024.

  2. Upon successful completion of this Unit the student is able to: • Create context and data flow diagrams for a health care system (or system component) using appropriate Yourdon symbols and conventions • Create a process flowchart for a health care system (or system component) using appropriate ISO 5807 symbols and conventions. • Choose the correct scope and detail level for a process flowchart and data flow diagram • Read and interpret Gane-Sarson data flow diagram • Read and interpret UML class, activity, and state diagrams • Read and interpret an entity relationship diagram in crow’s foot notation Health IT Workforce Curriculum Version 2.0/Spring 2011

  3. So Many to Choose From • Several methods and notations for diagramming processes exist. Main ones include: • ISO 5807 Flow Charting • Yourdon (including Yourdon code, and Yourdon DeMarco) • Gane-Sarson • Unified Modeling Language (UML) • E-R diagram • They differ in notation and in the process aspects covered.

  4. Process Features • Context • Process steps • Information flow • Information content • Information transformation • Step sequence, control, and status • Who or what performs the process steps Health IT Workforce Curriculum Version 2.0/Spring 2011

  5. Methods for Diagramming Processes Health IT Workforce Curriculum Version 2.0/Spring 2011

  6. Process Features Yourdon data flow diagram • Context • Process steps • Information content • Information transformation • Step sequence, control and status • Roles (who or what) performs the steps ISO 5807 Flowchart Health IT Workforce Curriculum Version 2.0/Spring 2011

  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 to improve the performance of the U. S. public health system.1 Health IT Workforce Curriculum Version 2.0/Spring 2011
