Notes de l'éditeur
- Purpose: Key Message: Creation – the first part of our journey. As an embryo develops, its life blueprint is being established through the architecture of its DNA. The embryo’s genetic structure will dictate its capability, propensity for immunity or vulnerability to disease, and certain personality characteristics it will carry throughout life. Childhood – the formative stage. We are influenced by our exposure to the world around us and can influence our life blueprint in how we manifest and integrate ourselves with the world around us. Our understanding of our needs, both for growth and creativity, are our ’requirements’ that allow us to create value for ourselves and those who come into contact with us. Adulthood – where we hone our skills and perform within expected societal parameters. We strive to improve our capabilities continually and define our value. By this time, we have built a complex network of relationships and dependencies to others. The world we live in has become far more complex than in childhood and managing our lives more challenging.

- Diagram: Shows the Core ITIL V3 publications/books. Setting the scene (middle) is Service Strategies, laying out guidelines for the IT organization, how to deliver value, which service portfolios to offer, etc. Service Design – translates strategic plans and objectives into designs and specifications ready to be built. Service Transition – takes the IT service design and implements it into the production environment. Service Operation – management of the IT services on a day-to-day basis Continual Service Improvement – ensuring that the IT service meets it’s service level objectives over-time; ensuring that the overall IT Service Management implementation is able to support the needs of the IT services and their customers – and that improvement/corrections are made as required. Each of the life-cycle stages is subject to Continual Service Improvement. Up to this point, we have defined the Core ITIL V3 publications.
