Enterprise & Solution Architecture (ESA)


Enterprise & Solution Architecture (ESA)

Our Enterprise Architecture (EA) practitioners facilitate the alignment between business goals and IT landscapes based on EA standards. When business models change, we help define a roadmap that reflects these changes by optimizing landscapes and underlying business processes. In addition, we assist clients in defining and implementing EA methods, tools, organizations and standards to efficiently and effectively govern their IT landscapes.

Key Questions

  • How do I derive a cost-efficient Enterprise Architecture based on business goals?
  • What is the impact of Digital Transformation on my Enterprise Architecture?
  • How do I govern Enterprise Architecture changes in a non-business-disruptive and agile way?
  • What are standard and leading-practice architectures in my functional domain?

Our answers

1) EA Capability Setup

Assess and improve your EA organization, its governance structure, roles, processes, tools and standards


A robust Enterprise Architecture program is critical to meet the key CIO priorities. The 2015 Deloitte global CIO survey (Link: ) identified key technology priorities

  1. Improve existing business processes: 46% of respondents said improving existing business processes is their primary focus for the next 12 months
  2. Reducing IT costs and driving efficiency: 37% of respondents said Reducing IT costs and driving efficiency is a high priority
  3. Assisting in business innovation: 37% of respondents said assisting in business innovation – developing new products and services continues to be a key priority

This leads to:

  • Effectively use existing assets, reuse best practices and artifacts aggregated by the Enterprise Architecture department to accelerate delivery of new projects
  • Reduce Technical and Architectural debt by leveraging Enterprise Architecture to review existing solutions and define organization standards and governance process for future solutions
  • Realize organization strategy by implementing the roadmap and intermediate transition architectures defined by the enterprise architects

We offer a generic EA approach to get an insight into and manage IT architecture complexity and support your organization to successfully implement and develop your EA Capability.
