What makes Enterprise Architecture a real business partner

Publish date:

Architecture principles, of course, take into account context and business challenges. But Business Architecture puts forward many concepts that make the real difference.

Enterprise Architecture is based on 4 pillars: Business Architecture, Applicative / Integration Architecture, Information Architecture, Infrastructure Architecture.

For years, Enterprise Architecture (EA) teams have developed the last 3 pillars in their companies: referential flows, applicative cartography, pivot formats, servers and networks. These are generally well documented, with a structured governance allowing them to be updated.

EA thus allowed a better knowledge, even appropriation of the Information System, which is a very important objective.

After having implemented SOA precepts (sometimes with great hardships), the information system must now facilitate the digital transformation, open up and communicate with partners/customers/suppliers’ information system, enable data valorization while respecting data privacy, enabling IoT to flourish etc. These huge challenges need to be prioritized and handled with business teams to facilitate businesses / IT alignment and selection of technological investments that fulfill business strategies.

Architecture principles, of course, takes into account context and business challenges. But Business Architecture puts forward many concepts (value chain, business capabilities and so on) that are still too little developed in the EA frameworks such as TOGAF.

More importantly, in today’s tech-advanced world, soft skills of facilitation and communication are very crucial: an Enterprise Architect needs to develop these to meet challenges in order to make Enterprise Architecture a real business partner.
