System State Diagram

MermaidMap how systems, objects, or processes transition between different states based on events or conditions. This template shows all possible states and the triggers that cause transitions — helping teams design robust behavior, catch edge cases, and document how things should work. Essential for software design, workflow automation, or explaining any system that changes over time.
How to create a System State Diagram
To create a system state diagram, follow these steps:
01.
Identify all states
List every distinct condition or mode your system can be in (e.g., Still, Moving, Crash).
02.
Define initial state
Determine where the system starts when first activated or initialized.
03.
Map transitions
Identify what events, actions, or conditions cause movement from one state to another.
04.
Determine end states
Specify which states represent completion or termination of the process.
05.
Create state nodes
Add labeled boxes or circles for each state in your system.
06.
Draw transition arrows
Connect states with arrows labeled with trigger events or conditions.
07.
Check completeness
Ensure every state has appropriate entry and exit paths.
08.
Review & validate
Test the diagram with real scenarios to confirm it covers all possible behaviors and edge cases.

Captive Portal Authentication Flow
A network flow diagram for captive portal authentication in an educational institution — showing how student devices move through 802.1X/RADIUS authentication, dynamic VLAN assignment, and captive portal fallback. Two paths are modeled: authenticated devices go straight to the student VLAN; unauthenticated BYOD devices hit the quarantine VLAN and get redirected to the portal. Built for IT administrators and network architects who need to document or communicate their access control architecture.
