Enterprise Architecture includes the following components: mission, stakeholders and customers, processes, applications and infrastructure, networks, and data.
EA facilitates improvement of processes : -
- Discovering business processes that require change
- Efficiently and continuously managing change via clearly defined documentation
- Developing and implementing enterprise-wide procedures
- Encouraging effective enterprise-wide communication, which, in theory leads to better decisions.

Holistic EA is pragmatically developed through the ongoing collaboration between business role players, the IT executive team, and the EA team.
In order to understand EA and our solution offering, it is important to comprehend how the knowledge frameworks, the EA Capability, and the Business, Information, Data, Application and Technology (BIDAT) architectures are systemically inter-related.
