Successfully embedding change is one of the biggest challenges faced by organisations. This publication explores what is meant by organisational culture, looks at the challenges faced by those trying to embed IT Service Management change, and proposes the adoption of a new and innovative framework which provides a portfolio approach. The framework can be used for strategic, tactical and operational change of all sizes and complexity, and covers: what the challenges are; the framework - what is trying to be accomplished; the portfolio approach; commitment; expectations; building momentum and application.
