Enterprise Architecture (EA) has been presented
as a methodology of managing complex systems. Using the concept of Collaborative
Enterprise Architecture to (a) 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. (b) 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. (c) Discuss the concept of TCO and their associated
calculators as they relate to IT by providing examples of use and application.
