Frequently Asked Questions
What's the difference between a flowchart and a diagram?+−
Flowchart specifically shows process flow with decisions. Diagram is broader — includes flowcharts, mind maps, network diagrams, etc.
Should every step be a separate shape?+−
Yes for clarity. Combining steps creates ambiguity.
Can I use multiple start/end points?+−
Generally one start, multiple ends are common. Multiple starts confuse readers — use only when truly parallel processes.
Is there a flowchart standard?+−
ISO 5807 defines basic symbols. ANSI also has standards. Most flowcharts follow informal but consistent usage.
Best tool for flowcharts?+−
Lucidchart, draw.io, Microsoft Visio for advanced. Online makers for quick simple ones.
Can flowcharts replace written documentation?+−
For complex processes, complement them. Visual + text together is best.
