A process flow diagram is a graphical representation of the steps involved in a particular process. It is an easy-to-understand visual representation of how a process works. Process flow diagrams are also known as 5-stage templates. They are used to help people understand the steps involved in a process and how they work together to complete the overall goal. A 5-stage template is made up of 5 boxes that represent different stages in the process flow such as planning, design, development, deployment, and maintenance. Each box has its own name, content, and color that helps people identify each stage easily and quickly.
