De eerste 90 dagen: sneller en slimmer een vliegende start maken

The book offers concrete steps, but I wonder how many actually implement them and see results. Did anyone find a particular tactic especially effective when starting a new role?

While the advice is solid, some of us face unique challenges that might not fit neatly into the framework. I'm curious if others struggled to adapt any of the strategies to their specific context.

The emphasis on this timeframe seems deliberate, but I wonder if it was based on research, personal experience, or a combination of both. How did this focus shape the overall approach of the book?
