Notes on system flowcharts A system flow chart can answer the following questions: 1. Who process data (entities, persons) 2. How to process data (activities, verbs) 3. Where are data stored (data storage) 4. What are inputs to data processing (documents) 5. When do activities occur (top to down, left to right) Please follow the steps below to draw flow charts Step 1: identify and highlight internal entities (who process information); external entities (who just send in or receive information). Write down the names of internal entities as the headers and draw a line in between the internal entities. Step 2: identify activities (processes) and highlight the verbs. Step 3: identify documents and circle them Step 4: identify data stores and underline them Step 5: draw activities for each entity in sequence.
