Enterprise Architecture (EA) has been presented as a methodology of managing complex systems. Using the textbook and other resources,

1. Discuss the principles of managing complexity and relate some of these principles to organizations that must contend with complexity. In addition, present a working definition of Lean and Agile methodologies and principles, then compare and contrast them and demonstrate their application to a real business/IT real world scenario. Sometimes the complexity to manage comes from external stakeholders such as suppliers, government agencies, etc. An interoperable methodology must exist to integrate EA systems with these external partners. Research some strategies to efficiently integrate EA systems with the systems of external partners.

Systems consolidation is essential for any EA to be efficient and effective. Systems consolidation attempts to take multiple streams of information from multiple systems and consolidate that information in one area.

2. Identify some advantages to incorporating systems consolidation and discuss how this can be facilitated. In addition and keeping in step with a collaborative EA, the total cost of ownership (TCO) can be a difficult measure, especially for IT personnel. The use of a TCO calculator can aid in determining the true cost of IT projects, hardware and software replacements, etc.

3. Discuss the concept of TCO and their associated calculators as they relate to IT by providing examples of use and application.
