Jake IT - Fault Finding Methodology.<\/strong><\/p>\n

What exactly is not working? Who is affected? When did it last work? What changed recently? What DOES still work?<\/p>\n

Map the System: Login issues are in the Authentication path.<\/p>\n

Internet issues are in the Network path.<\/p>\n

Application failures are in the Dependency path.<\/p>\n

Ask; what components are involved? What talks to what?<\/p>\n

What must succeed for the overall function?<\/p>\n

3 Trust the test data over intuition. Prevent pre-bias model fixation as the cause<\/p>\n

4 Scope reduction \u2013 is one user or many affected?<\/p>\n

5 Change one thing at a time, log it so you know what you did, then test the change.<\/p>\n

6 Authentication flow is: Client > Auth Provider Service > Policy Token granted or not.<\/p>\n

7 Assume the system WORKS! Suspect an incorrect config first: Firewall error? Policy? Location (IP block?)? Network Trust issue?<\/p>\n

8 Document while testing: Symptoms > Tests > Results. What has been ruled? Review plan.<\/p>\n

9 Slow down when things get odd: Is it multiple fails, an edge case, bad assumptions? Hidden dependencies? Still not solved? Redefine the system, the problem, then remap the system.<\/p>\n

Summary:<\/p>\n

Define the fault clearly.<\/p>\n

Use a Map the System mindset<\/p>\n

Trust the data<\/p>\n

Reduce the scope<\/p>\n

Test deliberately, don\u00b4t guess.<\/p>\n

Follow the process directionality<\/p>\n

Respect the config logic.<\/p>\n
