IT of an organization has to be managed well to get desired result from usage of information technology. Up till now, various frameworks are developed to manage it well as COBIT and ITIL, containing all processes which can be handled in IT management. They are complementary frameworks rather than competitors. Due to this reason, organizations must implement both of them. This book provides organizations to meet requirements of these frameworks/standards which are process based frameworks and standards complementary to each other, with a unique implementation by taking unification of processes in a more simple and understandable way. Consequently, it provides reduction in the duplicate work and prevents inconsistencies that may occur. In addition, including CMMI level two requirements motivate the organization to implement higher maturity level of CMMI. Moreover, this study provides organizations to implement ISO/IEC 27001:2005 management structure which establish a foundation for extension to technical structure of it. Besides these, this study provides an alignment of frameworks model and COBIT and ITIL which helps organization to trace ITIL and COBIT simultaneously.
