The degree of development and efficacy of an organization's enterprise architecture practice is referred to as enterprise architecture (EA) maturity. The discipline of enterprise architecture aims to match the information flows, technology, human resources, and business processes of an organization with its strategic goals and objectives. A scale reflecting how well a company has developed and institutionalized its enterprise architecture capabilities is frequently used to evaluate the maturity of enterprise architecture.
The stages of Enterprise architecture maturity are:
i. Ad Hoc or Initial Stage: restricted knowledge and comprehension of corporate architecture. EA principles may be applied in some isolated projects or endeavors, but they are not consistent or coordinated throughout the company.
ii. Repeatable or Managed Stage: This company implements certain formal procedures and starts to see the benefits of enterprise architecture. An endeavor is underway to record and conserve architectural relics.
iii. Defined Stage: enterprise architecture procedures and techniques that are clearly specified. The organization is aware of how EA advances corporate objectives. An official EA framework is in existence.
iv. Managed or Quantitatively Managed Stage: The enterprise architecture processes are actively managed and measured by the organization. Metrics and key performance indicators (KPIs) are used to evaluate how EA affects company results.
v. Optimized Stage: The organization's strategic planning and decision-making procedures fully include EA methods. The company has a strong innovation culture and consistently modifies its EA procedures to satisfy changing business requirements.
