Ongoing digitisation, along with the risks of digital disruption, mean today's Enterprise businesses are more reliant than ever on their IT Organisations to be successful; but business cannot wait on IT. Instead, Enterprise IT Organisations must transform to Fast IT to keep pace with the various lines of business, operate more agilely and efficiently than ever before, while simultaneously supporting rapid innovation of transformative capabilities. The IT as a Service (ITaaS) Framework-based on the work pioneered by Cisco's own global IT organisation-is a proven model for transforming to an end-to-end Services Organisation, and shifting the underlying culture of the IT organisation as a foundation for Fast IT. Now, the developer of the ITaaS framework provides you with an in-depth guide ensuring that your Services Transformation achieves the intended value outcomes of establishing IT as a trusted advisor to the business, and operating IT like an agile, competitive, and cost-efficient business within a business. Drawing on his pioneering experience, the author emphasises implementation alongside theory, illuminating entertaining stories from his own consulting experience, and pulling back the curtain on Cisco IT's own revolutionary tranformation alongside best practices, templates, and other artifacts to guide your Services Transformation.
