  1. Can accept inputs of various quality and type, and produce the same high quality output

  2. Can accept inputs of various quality but same type, and produce the same high quality output

  3. Can accept inputs of same quality but different type, and produce the same high quality output

  4. Can accept inputs of same quality and type, and produce the same high quality output

Explanation

A Robust System is designed to handle variation in input quality (different performance levels) AND input type (different categories/sources) while still consistently producing high-quality output. This differs from systems that only handle variation in one dimension. Robustness is a key Six Sigma design principle for creating processes that work reliably in real-world conditions.
