The four steps you perform to map out a flow include: identification, information gathering, interviewing, and analysis. In the first stage, you determine the basic requirements of the workflow, its value, and its goals. The second stage helps you collect information, such as a comprehensive list of the stakeholders for this workflow. You proceed to meetings with people responsible for particular tasks, where you listen to input (surveys, discussions, etc.). As a result, you get an in-depth analysis of your process that you can use to improve it.
