The ITIL processes which were an integral part of the DevOps world have been merged with the DevOps framework reflecting the current emphasis on product models rather than viewing project and support models separately. book starts with the basics of digital transformation before exploring how this works in practice that is people processes and technology and org structures. It delves into value streams that are the basis for ITIL and DevOps highlighting the differences between the methods of the past and new methodologies needed to ensure products to meet contemporary expectations.
