Workflow Analysis for EHR Selection and Implementation
Moving from paper to an EHR, or from one EHR to another, requires significant changes in nearly all processes and their attendant workflows.   Success requires attention to both group processes (processes whose workflows send work item from one person to another) and individual processes ( processes whose workflows are completed by a single person).   This series explains the characteristics of group and individual workflows, how to recognize them and document workflows, and who to create a test script that can be used for software selection.

Petri Nets and Graphs
As surprising as it may seem, workflows can be described mathematically.   Even better, the mathematical properties of workflows can be modeled visually using Petri nets. With Petri nets it is possible to study workflow properties such as concurrency and state.   This series offers an introduction to Petri nets and graph theory. No math knowledge is assumed on the part of the reader.

Modeling Tools and Techniques
Workflow concepts are integral to areas such as usability, patient safety, practice optimization, and clinical decision support. Use cases captures aspects of workflows as well.   The wide variety of situations in which workflow concepts are useful, makes workflow modeling an important tool for understanding clinical software and clinical systems.   While most healthcare workflow models use flowcharts and/or swim lanes, there are tools available that are designed specifically to capture key workflow elements such as resource use and information movements. YAWL, is a workflow modeling tool that allows one to capture all workflow properties within a single visual modeling environment.   This series discusses the basic features of YAWL and offers modeling tips and examples.
