Task Batching Blueprint

I want to implement task batching to reduce context switching. My typical tasks include {{TASK_TYPES}} and I currently switch between tasks approximately {{SWITCH_FREQUENCY}}. The tasks that suffer most from fragmentation are {{FRAGMENTED_TASKS}}.

Create a comprehensive task batching system:
1. Task categorization by cognitive similarity
2. Optimal batch sizes for each category
3. Daily and weekly batching schedule
4. Communication and email batching protocol
5. Meeting batching strategies
6. Handling urgent requests within batches
7. Transition rituals between batches
8. Flexibility guidelines for unexpected demands
9. Tracking batch effectiveness
