Introduction
The recent 15% drop in accuracy of DeepMind's AlphaFold protein structure predictions is a critical issue that demands immediate attention. As we analyze this problem, we'll follow a systematic approach to identify, validate, and address the root cause while considering both short-term fixes and long-term implications for the product.
Our analysis will cover issue identification, hypothesis generation, validation, and solution development. We'll start by clarifying the context, then rule out external factors before diving deep into the product's mechanics, metric breakdown, and potential root causes.
Framework overview
This analysis follows a structured approach covering issue identification, hypothesis generation, validation, and solution development.

Clarifying Questions (3 minutes)
Why it matters: Recent changes could directly impact prediction accuracy. Expected answer: Yes, there was a model update two weeks ago. Impact on approach: If confirmed, we'd focus on the changes made in the update.
Why it matters: Changes in evaluation methods could affect accuracy measurements without actual performance decline. Expected answer: No changes to the evaluation process. Impact on approach: If unchanged, we'd look more closely at the model itself.
Why it matters: Resource constraints could impact model performance. Expected answer: No significant changes to infrastructure. Impact on approach: If confirmed, we'd focus more on software-related issues.
Why it matters: Changes in input data could affect overall accuracy metrics. Expected answer: Some increase in complex, multi-domain proteins. Impact on approach: If confirmed, we'd investigate how AlphaFold handles different protein types.
