As a best practice Salesforce always suggests preferring “point and clicks” over code i.e. use Workflow rule or Process builder over Triggers. Now, Salesforce Admins can perform so many tasks using Process builder which were only possible by writing Triggers in past. Automate your business processes using user-friendly visual interface rather than Apex code.
With Winter 17 release, Process Builder capabilities have been enhanced. Within a Process, we can invoke another Process!! Just build a process and call it from multiple processes or from multiple action groups in the same process.
In past, it was only possible for coders to write reusable code. With invocable processes, we can reuse certain processes and call it from multiple processes or from multiple criteria nodes within the same process.
In case we need to follow same steps for multiple process condition than we can make that as generic invocable (reusable) process instead of adding all those steps again and again.
It is not only saving time but also improve manageability and reusability. Isn’t it interesting and simple!
