Processes
Computer-based information systems enable or facilitate some set of defined processes or procedures.
Process Analysis
The act of describing a process in writing usually leads to a better understanding of that process.
Process Diagramming
One good way of demonstrating and communicating your understanding of a process is by diagramming it.
Process Diagrams depict the flow and scope of a process from start to finish. Process diagrams should ideally be accompanied by written descriptions of the various component sub-processes.
Process Diagramming Tools
Tools with diagramming capabilities:
Word Processing Software (e.g. Google Docs, MS Word)
Presentation Software (e.g. Google Slides, MS PowerPoint)
LucidChart (recommended)
Process Diagram Shapes
Process diagrams generally employ a standard set of shapes, each with a specific meaning:
shape | purpose |
Circle or Oval | A "terminator" which indicates the start or end steps of the process |
Square or Rectangle | A sub-process, or step in the overall process |
line with an arrow | Points from one step to another to indicate sequential flow, including sub-process dependencies |
Diamond | Denotes a "decision-point" in the process, including conditions under which different outcomes are possible |
Square with a squiggly bottom | A "document" produced by, or related to, a step in the process |
Additionally, some process diagrams use visual separators called "swim lanes" to indicate which stakeholders are responsible for each sub-process.
Process Re-engineering
After learning more about the process, analysts are able to identify "pain points", or areas in need of improvement. And they can identify ways to simplify or re-engineer the process.
