A standard operating procedure (SOP) is a clear, step-by-step document that describes how to complete a particular activity. It should be noted here that Flow charts are simple diagrams that map out a process so that you can easily communicate it to other people. You can also use them to define and analyze a process, build a step-by-step picture of it, and then standardize or improve it. Instead of creating a flowchart on complex tools, use EdrawMax Online as the free flowchart maker that offers team collaboration where your remote team members can make the life changes to your flowcharts. As the SOP Flowchart for marketing example graphically illustrates, a standard operating procedure, on the other hand, ensures that every employee uses the same process to receive a particular output. Imagine that you are having a hard time logging in to an application at work.
