A business process, you say?

A business process, you say? • Anywhere human work and/or systems are combined to produce value ! • Business processes involve everyone • The employees being part of it • The customers paying for them • The bosses trying to optimise them • ... and the developers implementing them

A business process, you say? • Processes are visualised (with flowcharts) ! ! ! ! ! • Why would I use a picture for creating software? • Improve communication and understanding of both tech and non-tech people • Manage complexity • Orchestrate distributed cloud services

Why would I execute those 'pictures'? Business  Processes  automated Metrics Optimization

So, it's basically a picture? • Yes, and no: it's a picture (or diagram) with • standardized building blocks • technical XML representation ! • The industry accepted standard: BPMN 2.0 ! • The Activiti engine takes BPMN 2.0 XML and executes the system calls and create tasks for the human workers

The diagram Human  work System  calls Boss  needs  to  approve  expense  ...   Joey  needs  to  call  this  customer!   Customer  can't  book  ticket  ...
