This management guide offers an introduction to the IT Capability Maturity Framework™ (IT-CMF™), 2nd edition. The IT-CMF offers a comprehensive suite of tried and tested practices, organizational assessment approaches, and improvement roadmaps covering key IT capabilities needed to optimize value and innovation in the IT function and the wider organization. It enables organizations to devise more robust strategies, make better-informed decisions, and perform more effectively, efficiently, and consistently. IT-CMF is: • An integrated management toolkit covering 36 key capability management disciplines, with organizational maturity profiles, assessment methods, and improvement roadmaps for each. • A coherent set of concepts and principles, expressed in business language, that can be used to guide discussions on setting goals and evaluating performance. • A unifying (or umbrella) framework that complements other, domain-specific frameworks already in use in the organization, helping to resolve conflicts between them, and filling gaps in their coverage. • Industry/sector and vendor independent. IT-CMF can be used in any organizational context to guide performance improvement. • A rigorously developed approach, underpinned by the principles of Open Innovation and guided by the Design Science Research methodology, synthesizing leading academic research with industry practitioner expertise.
