Example text

The script task contains a out:println variable B, which is a Groovy reserved word within the Activiti script task for printing text to the system console. Also notice that the isbn variable can be used directly in the script code without any additional programming. The user task C contains a potential owner definition, which means that the task can be claimed and completed by users that are part of the group sales. When you run this process in a minute, you’ll see in the Activiti Explorer that this user task is available in the task list for the user kermit, who is part of the sales group.

Optimization—Based on new insights, changing business requirements, and monitoring results, the implemented business processes will need to be optimized. When the optimization phase is done, the business process goes into the design phase again and the cycle is completed. The BPM life cycle shows that implementing business processes is an ongoing process due to the everchanging business environment and need for optimization. How long it takes to walk through all five steps of the BPM life cycle depends greatly on the business environment and the ability of a business to execute.

You also started the Activiti process engine, deployed a book order process, started a process instance, and did some unit testing on it with a couple lines of Java code. It’s obvious that Activiti provides you with a powerful API and tool stack to run your processes. But how can you model and implement these processes? 0 in the next chapter. 0: what’s in it for developers? 0 This chapter stands out from the others in this book because it doesn’t contain a single code example. 0 palette. 0, feel free to skip this chapter and move on to exploring the Activiti framework in chapter 3.
