Systems Differential Diagnosis Framework

In medicine, symptoms are just surface signals. They tell us something is wrong but not why. Diagnosing the true cause requires method, patience, and a structured approach. That same logic inspired the Systems Differential Diagnosis Framework (SDDF) — an ITIL-aligned model for understanding and resolving complex system failures. Like a doctor applying differential diagnosis, SDDF guides teams through evidence gathering, hypothesis testing, and confirmation, transforming reactive troubleshooting into preventive intelligence.
