I highly recommend this book for both CTOs/CIOs at the beginning of their career and for experienced technology leaders on a quest to continuously improve and re-calibrate themselves.
The method of the book is to distil decades of experiences into simple learnings. It’s a cookbook. It creates a mental grid of domains and principles for a technology leader to succeed.
It also provides entry points to deepen your knowledge in specific subjects, always pointing back to the larger context.
Well done. Fun to read.
