Enterprise Systems Architecture: Aligning Organisational Business Operating Models to Technology Landscapes

Enterprise architecture is often discussed through frameworks and technology choices. Daljit Roy Banger’s Enterprise Systems Architecture starts with a broader question: how should an organisation’s technology landscape support the way its business operates? Its answer is a practical architectural mindset for making that connection visible and guiding decisions across complex systems.

Rather than promoting a particular framework or implementation, the book uses a notional “Stack” to organise ideas and show how technology enablers relate to business needs. The emphasis is on alignment, traceability and considered architectural thinking—useful territory for people working where business priorities meet technology delivery.

Architecture as a way of thinking

Banger distinguishes architectural thinking from any single method, doctrine or technology. Frameworks, patterns, processes and best practices can support the work, but the central concern is understanding the wider system and how its parts contribute to organisational goals.

Follow the connection from business to technology

The book’s Stack provides a structure for examining the relationship between business operating models and technology capabilities. It is presented as a way to organise architectural thought and work packages, and to make the links between business needs and technology choices easier to trace.

From architectural perspective to ICT strategy

Across five short, self-contained sections, the publication develops its enterprise systems architecture viewpoint and culminates in the development of an ICT strategy. The sections can be read independently, making the book suitable for focused reference as well as a broader introduction.

For students and working practitioners

The book identifies students and practitioners as its readership, including enterprise, solution and technical architects, business analysts, CTOs and stakeholders involved in delivering technology services. It offers a framing for readers who want to think more clearly about how systems support an organisation’s operating model, without presenting itself as an exhaustive treatment of every architectural topic.

For readers seeking a concise introduction to aligning business operating models with technology landscapes, Banger’s book offers a structured starting point grounded in the architectural mindset.
