Businesses are evolving quickly today, at an ever higher speed. Integrated IT services are key in enabling this. The IT service at functional and application level is where the value is realized for the user. That also means all support, application and technical teams and professionals need to work together in the most appropriate way across the entire stack. This may even be one of the most relevant challenges in IT organization design today.
While some organizations may need to create a clear distinction between "technical" or "infrastructure" professionals compared to "application" professionals, others may opt for other organizational structures. Services that are consumed from the Cloud may be available on the infrastructure or platform level, or even on the software / application level. Integrating such Software-as-a-Service services comes with new challenges. And even with internal or private cloud and dedicated IT environments, managed internally or with partners, close alignment between the components used and the business functionality running on them is key to maximizing the value to the user.
That makes it strange to use a framework that is still called the "IT Infrastructure Library". While the initial challenge may have been about running an infrastructure, the focus for IT Service Management is much broader today. Application support and functional support are just as relevant as keeping the hardware running. Some have tried to translate this infrastructure library to an "Application Services Library" or even an "Business Information Services Library", both in fact focused subsets of ITIL. But it is not relevant anymore today to only look at the pieces of the puzzle. The entire picture matters, as today's version of ITIL clearly acknowledges.
