My definition of EA is given in the image above. EA enables optimum unification of Peoples, Processes and Resources which creates a Environment for excellence . Such environment is unique and can be called signature or finger print environment of the enterprise . In such signature environment people , process and resource work in harmony to create sustainable competitive advantage for the enterprise . Signature environment can not be easily copied by competitors. While creating a signature environment, the most important issues are people, process and then resource issues with their importance being in the same order. First an enterprise should look into people and process issues. Once people and process issues are resolved , the relevant and required resources should be considered. IT is one of the most important resource required for an enterprise. Other important resources are facilities and systems like manufacturing systems, production systems etc.
