The strategies feel very tailored and practical, but I wonder what influenced the selection of topics. Were these based on personal experience or common industry challenges?

I work in marketing and the agile methods here seem different. I'm curious if the principles in the book can be adapted beyond software development.

Estimating has always felt like a guessing game to me, so I wonder what motivated the deep dive into estimation strategies and how the author developed his approach.
