Enterprise Architecture - Maturity Stages
Enterprise Architecture is no static, one-time issue. As a company's business undergoes changes, an enterprise architecture needs to get adapted as well. The journey can be described by starting with the business silo architecture. Therein companies primarily make IT investments to meet local business needs. Passing through the two other stages, which are often called “standardized technology” and “optimized core”, the journey ultimately leads to the business modularity stage (e.g. enterprise SOA). It is quite obvious that this evolution of enterprise architecture implicates changes within the organization, especially of the role of the enterprise architect.
