Choose the Right Chunking Strategy for the User Experience

Analyze chunk size and overlap as two coupled parameters, compare semantic chunking to fixed-size chunking, and write a chunking requirement around behavior instead of a technical number.

Distinguish how chunk size and overlap each affect answer quality

Compare semantic chunking to fixed-size chunking through a worked example

Write a chunking requirement that describes the needed behavior, not a specific number

Choose the Right Chunking Strategy for the User Experience

Lesson 16 only touched the problem: chunks too large get noisy, too small lose context. Now we go deep on how to choose the right chunking strategy and why this is a PM decision, not something an "engineer just tunes the number" on.
