Workflow in Informatica is typically seen as a set of interconnected tasks that all need to execute in a specific order or a proper sequence. In every workflow, a start task, as well as other tasks linked to it, are triggered when it's executed. A workflow represents a business's internal routine practices, GENERATES output data, and performs routine management tasks. The workflow monitor is a component of Informatica that can be used to see how well the workflow is performing. You can create WORKFLOWS both manually and automatically in the Workflow Manager. 

To HELP you develop a workflow, the Workflow Manager OFFERS the following tools:  

• Task Developer: This tool allows you to create workflow tasks.
• Worklet Designer: Worklet designer is an option in Workflow Manager which combines (groups) MULTIPLE tasks together to form a worklet. The term worklet refers to an object that groups multiple tasks together. Unlike workflows, worklets don't include scheduling information. It is possible to nest worklets inside workflows.
• Workflow Designer: This tool creates workflows by connecting tasks to links in the Workflow Designer. While developing a workflow, you can also create tasks in the Workflow Designer.
