Enterprise architecture (EA) is a discipline where the enterprise wide changes and business challenges can be dealt with effectively. According to John Zachman, “Enterprise architecture is a discipline which should help business managers to address their problems scientifically and quickly. End result is not to create the models, but to solve the enterprise problems”. There are multiple factors which necessitate the adoption of enterprise architecture,
- Business growth due to expansions, mergers and acquisitions etc.
- Financial challenges such as lights on cost reduction, business model change etc.
- Demands and challenges due to various IT trends such as new products and frameworks appearing in the market
- Challenges with governance, people, processes, tools and capabilities.
