¶ … Alignment: Summary and Analysis In the peer-reviewed article Complementarities Between Organizational IT Architecture and Governance Structure (Tiwana, Konsynski, 2010) the authors contend that IT architecture and IT governance design and implementation is highly dependent on systematic and process-related interdependencies that will often shift significantly over the lifecycle of any IT framework. This makes the task of ensuring adoption of IT architectural components, as diverse as Service Oriented Architectures (SOA), Web Services, Platform-as-a-Service (Paas) and other nascent enterprise platform technologies, are continually aligned to the business' strategic programs, plans, strategies and initiatives.

Through a well-defined methodology and use of advanced statistical...

The conclusion is that greater organizational agility can be attained by use of systematic use of IT architectures and governance frameworks. It architecture modularity as defined by loosely coupled integration of key process and system areas in conjunction with standardization of IT architectures and governance frameworks are a foundation of greater IT agility and over time, greater IT alignment to business objectives (Tiwana, Konsynski, 2010). IT Governance influences the alignment of IT architectures and frameworks in the process.
