Learning BPMN 2.0: An Introduction of Engineering Practices for Software Delivery Teams

By Joshua Fuehrer and Wesley Almeida

Do you ever think of how you learn-by reading, watching, listening, and doing?

Maybe you use all four?

Many of us go through life unaware of how we learn or acquire a skill set; we just learn it.

We all have the capability to learn. From that perspective and with a passion for business process

Preface

I never envisioned the positive feedback received from the BPMN community and the success of Joe and my first book. So first and foremost, thank you.

With that feedback, coupled with my ongoing research, and experience in the field, I thought it was time to share the 2ND EDITION of Learning BPMN 2.0.

With the 2ND EDITION, Wes Almeida joined the team to help extend the learning of BPMN with a lead engineer perspective. As software engineers, we like to get our hands on the code and get started right away. We have written thousands of lines of code in our career, helped others on StackOverflow with their problems, and probably even contributed to a few popular libraries. We’ve done all this without understanding modeling or thinking about how to communicate complex processes to others. We’ve made it this far and do not need to understand modeling. But then comes the day when we get so good at the job that someone trusts us to be the engineering lead of multiple teams. As an engineering lead, we must implement new system designs from a systems architect or explain why refactoring a legacy part of a system would be cumbersome simply by looking at old models written by a previous team. Sure, it is possible that you can review the code instead of a diagram to get by, but that won’t scale very far. Additionally, although you may survive those engineering lead days without understanding modeling languages, one day someone will trust you to architect a complex system of your own. Now there is no escape! As part of the update, I will provide learning experiences to help you understand BPMN in the context of development, engineering, and security processes with real-world examples and where relevant coding examples.

This updated edition intends to provide you, the reader, with the original text, learning experiences, and material from the first edition of Learning BPMN
