The book explains that successful digital transformations typically require 2-3 years for initial implementation, with continuous evolution thereafter. However, organizations can achieve significant milestones within the first 6-12 months if they follow the prescribed methodology.

McKinsey's approach uniquely combines organizational rewiring with technological implementation, focusing on building sustainable capabilities rather than just implementing new tools. The methodology emphasizes creating self-sustaining digital ecosystems rather than one-time transformations.

While some new hiring may be necessary, the book emphasizes that successful transformations primarily focus on upskilling existing employees and creating internal digital capabilities. The authors provide detailed frameworks for assessing current talent and developing targeted training programs.
