- 1. 1 Introduction to Extend Chapter 7 Business Process Modeling, Simulation and Design
- 2. 2 Introduction to Extend 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.
