From chapter: Epilogue - Frequently Asked Questions, pp. 222–230
The epilogue answers common questions. Eleven companies made the cut because the standard was tough, and the probability of finding them by chance is less than 1 in 17 million. Collins covers why only public US firms, why no tech firms, how the board should pick Level 5 leaders, how Cisco shows a young tech firm can have one, how to apply first who when talent is short or the wrong people are hard to remove, and where to begin: work sequentially from first who and keep working on Level 5.
