List the Steps Use a verb to start the task description. The flowchart can either show the sufficient information to understand the general process flow or detail every finite action and decision point. Sequence the Steps Use post-it notes so you can move tasks. Do not draw arrows until later. Boxes or rectangles show task or activity performed in the process.
Arrows show process direction flow.
Usually there is only one arrow out of an activity box. If there is more than one arrow, you may need a decision diamond. System Model Draw charts using system model approach. Input - use information based upon people, machines, material, method, environment. Process - use subsets of processes in series or parallel.
