For years now, ITIL (formerly known as the IT Infrastructure Library) has remained the cornerstone and industry-standard best practice framework for supporting, managing and aligning IT Service Management with the needs of the business. Trademarked by AXELOS, ITIL acts as a governing agent for IT, and uses the ITIL Service Lifecycle to map the entire journey from customer needs and requirements all the way through continual improvement of services.
ITIL has been deeply entrenched into the fabric of enterprise IT for some time now, and despite the nascent contrarian opinion every now and then, it’s safe to assume that the framework’s popularity isn’t going to diminish any time soon. In fact, AXELOS is constantly changing and updating their certification courses in order to keep up with the times and shape ITIL’s commonly established principles to govern today’s modern technology and development trends. That said, becoming ITIL certified is a safe bet to stay prepared for the future, and the demand for educated ITIL experts in the fields of incident management, service management, change management and other ITSM related areas are still very high in 2017.

Good IT Service Management is about knowing how to integrate these factors into your development process, and this is where ITIL comes in. It covers the entire development lifecycle, from identifying requirements from a business and IT perspective, to designing and creating the solution, to delivering and maintaining the service in a state of continual review and improvement.
Problem management aims to resolve the root causes of incidents and thus to minimize the adverse impact of incidents caused by errors within the IT infrastructure, and to prevent recurrence of incidents related to these errors. A "problem" in this context is the unknown underlying cause of one or more incidents, and a 'known error' is a problem that is successfully diagnosed and for which either a work-around or a permanent resolution has been identified. The CCTA (Central Computer and Telecommunications Agency) defines problems and known errors as follows:
By adopting the ITIL framework, companies ensure that their services are delivered according to a set of consistent, well-defined processes that incorporate best practices and processes, resulting in a predictable level of service for users. The benefits of ITIL include reduced cost of service development and deployment, improved customer satisfaction with service delivery, increased productivity from IT personnel, quality improvements, better management metrics of services and increased flexibility in adapting services to changing business requirements.
Split over several levels and modules, ITIL covers everything from service strategies to continuous improvement, enabling practitioners to not only adapt IT service infrastructures, but also prepare for further changes down the line. This can help to foster sustainable productivity for businesses and create a better, more consistent experience for customers.
