How to Trace a Healthcare Application Issue End-to-End

A real issue rarely lives in one layer.

The useful move is to follow the path from the user-facing symptom back through every dependency that could influence the outcome.

Start with the symptom

Write down what the user actually sees, when it happens, and who is affected.

Walk the path

Think in layers:

user → endpoint → app → network → server → integration engine → database → downstream system

Each hop gives you a place to test, observe, and eliminate.
