Templates and tasks make up the basic building blocks of a Maestro workflow. Maestro requires a workflow template to be created by an administrator. When called upon to do so, Maestro will put the template into "production" and will follow the logic in the template until completion. The definitions of in-production and template are important as they are the defining points for important jargon in Maestro. Simply put, templates are the workflow patterns that define logic, flow and variables. Processes are templates that are being executed which then have process variables and assigned tasks in a queue.
Once created, a workflow template allows the Maestro engine to follow a predefined set of steps in order to automate your business process. When put into production, the template's tasks are executed by the Maestro engine or end users in your system. This blog post defines what templates and tasks are, and some of the terms associated with them.
