Enterprise & Solution Architecture

Given the rapid changes in technology and the businesses move towards digital operating models, IT organizations are thinking about their architecture needs in innovative new ways. Deloitte’s Enterprise and Solution Architecture professionals help clients refresh their enterprise architectures to support the new business direction, and leverage advances in technology areas such as cloud, mobile, digital, and analytics. We extend these services with solution architectures that support integrated solutions that perform well, are secure and can scale with the business. TS&A also has deep experience assisting organizations in setting up the Architecture functions including design of the function, definition of the architecture process and deliverables, and governance.

Your Challenge

Businesses are faced with disruptions in both technology and industry such as mobile and cloud, continually changing the operating model of business and IT. Desired is the capability to transform such disruptions into actionable, future proof organization blueprints covering governance, process, data, applications and infrastructure. Modification of an enterprise, and subsequent solution architectures based on the new needs, is a major challenge.

Blueprinting & Roadmapping

The right blueprints and roadmaps create potential to substantially improve strategy execution, IT portfolio management, and individual project delivery. We can help you bridge between strategy development and the transformation execution to get the maximum out of your resources. 


In the current business environment, businesses continually look for ways to meet their changing business needs through rapid technology implementations. The need for agility and speed leads to the consideration of agile software development methods instead of choosing for traditional approaches. Our team will not only provide you with a clear Agile vision, roadmap, and target state, but also hands-on coaching. 

Capability Development

For effective coordination and control, a well-organized Enterprise Architecture Competence is essential. This requires architects to have the right competences, knowledge, and experience of the matter. We can help you set up a clear organization design, train competent architects who are supported with the right methods, and give you the right tools to create value. 


In a fast digitalizing environment safeguarding the security of data is often a critical point for organizations. Many CIO’s struggle with the preservation of confidentiality, integrity, and availability of information used in the business processes, applications, and technology. Our comprehensive approach to design secure Enterprise Architectures consists of three fundamental elements: a shared language, integrated process and aligned deliverables. 

The Cloud

Two-thirds of chief information officers (CIOs) view cloud computing as a principal disruptive force in their businesses. Our cloud offerings are provided across seven capabilities. What emerges is a deep technical blueprint for your unique cloud solution, one that sets the stage for a deliberate, thoughtful transformation.
