8. Is this book still relevant in the year 2024?
• Target Audience: Enterprise Architects, CTO, & CIO.
• Although the book is published on the year 2006; it is being referenced in more
recent articles / books (Ex: Sogeti labs (2016), The practice of Enterpise
Architecture (2021)).
• Thanks to “Sergio Caredda” for the article “Operating Models: the theory and the
practice” (2021) that shows 17 different operating models. IMHO, The most
relevant one to Enterprise Architecture & IT in general was the “Ross Four
Quadrant Model”.
• Having companies transformation stories that is mentioned in the book ensure
confidence of your next steps.
• The book is still relevant as of year 2024.
