1. Introduction to Extend
Chapter 7
Business Process Modeling, Simulation and Design

2. Introduction to Extend
NOTE:
We recommend presenting this chapter by running Extend 6.0 directly, and interactively show how the program works.
However, for your convenience, we have attached a selection of the figures/screenshots from Chapter 7 of the book as the basis for an in class presentation without access to a computer with Extend installed.
