Root Cause Analysis (5 Whys)

Help me conduct a root cause analysis for this problem:

Problem statement: [DESCRIBE THE ISSUE CLEARLY]
When it occurred: [DATE/FREQUENCY]
Impact: [WHO/WHAT IS AFFECTED]
Immediate symptoms: [WHAT YOU CAN OBSERVE]
What you've already tried: [ATTEMPTED FIXES]

Apply:
1. **5 Whys technique** (dig to the root)
2. **Fishbone diagram** categories (People/Process/Technology/Environment)
3. Distinguish: symptoms vs. causes vs. root causes
4. Identify contributing factors
5. Prioritize root causes by impact
6. Recommend permanent fixes (not band-aids)
7. Prevention measures
8. Monitoring metrics to track improvement
