We have seen the different components of the KIE workbench throughout the book. This appendix will explain how all its components are bonded together through the UberFire framework, which allows us to have a configurable and extensible workbench environment. We will dedicate this appendix to discussing its structure and use, which will become useful if you wish to extend the tooling provided by jBPM6 for your own personal customization. This is an advanced topic, but will give you a full control over how to use the KIE workbench to fit it best to your company.
