Imagine you're designing a modern city—planning its districts, roads, utilities, and transportation systems. Every decision must balance long-term vision, current realities, and future growth.
Enterprise Software Architecture follows a similar structured approach. Just as a city evolves from strategic planning to detailed execution, IT solutions transition from high-level enterprise architecture to detailed UI and code implementation.
However, there’s a key difference:
- In urban planning, buildings and infrastructure must be constructed in a predefined sequence (e.g., you can’t build a skyscraper before its foundation).
- In software development, we can deliver software in pieces (like an MVP) and expand it iteratively.
Additionally, Solution Architecture represents an enterprise-wide software ecosystem—not just a single software product. A Solution typically consists of multiple software components that must integrate and function together. This is what differentiates Solution Architecture (Enterprise Software Architecture) from Software Architecture (a single software system).
Just as a city has multiple districts, utilities, and transportation systems that must work together, an enterprise solution consists of many software applications and integrations that must function as a cohesive system.

Plan & Develop Enterprise Software like a City
Many cities in the world have successfully implemented their modernization to be smart cities. They integrate IoT, smart grids, and data-driven transport policies, allowing real-time adaptation based on traffic, pollution, pedestrian flow, etc. Similarly, Enterprise Software Architecture and its Enterprirse Software must be able to plan, integrate monitoring, feedback, and continuous improvement mechanisms.
Major cities have been expanding their transportation systems (e.g. subway, etc) over a long period of time (some even over a century). This is just like software MVPs evolving over time.
Let’s take a look at Amazon. It started as a bookstore, then expanded into cloud computing (AWS), AI services, and e-commerce—each new service integrating like a well-zoned city district, like a growing metropolitan. Not only Amazon, just to name a few: Google, Facebook; also expanded into various services which are entirely different from their MVPs.
While software development and urban planning/building construction share many similarities, there are key differences—especially at the bottom layer (Software Architecture, Software Design, Information Architecture, UX & UI Designs).

Aspect |
City Planning & Building Construction |
Software Development |
|
Development Approach |
A city or a building is constructed in a predefined sequence—you cannot build the roof before the foundation. |
Software can be developed piece by piece (MVP, iterative releases), allowing functionality to be deployed without completing the entire system. |
|
Flexibility & Iteration |
Once a physical structure is built, major changes (e.g., moving a road or rebuilding a skyscraper) are costly and difficult. |
Software systems are designed for change—modular architectures, APIs, and cloud-based services allow continuous updates and scaling. |
|
Core Infrastructure vs. Modularity |
A city’s core infrastructure (electric grids, highways, underground utilities) is rigid—expanding or modifying them is complex. |
Software has core components (database architecture, system APIs) that become rigid once built, but many other parts can be modular and scalable. |
Nevertheless, if a more rigid, complex, costly, difficult City Development can be successful (like those examples), then what’s holding Enterprise Software Architecture and its Development not to be much better?
More Parallels
Stakeholder Engagement
· Urban planning heavily involves public hearings, citizen feedback, and regulatory approvals. Cities conduct public consultations to ensure new developments align with citizen needs. A city that ignores public input creates inefficient infrastructure. Cities also require zoning laws, environmental regulations, and political buy-in.
· Likewise, Enterprise Software Architecture requires User Research & Business Stakeholder Input. Software teams must gather user insights and business priorities before designing solutions. Software that ignores user experience and stakeholder feedback results in poor adoption and usability issues. Enterprise software must comply with various regulatory and compliance policies.
· Example: When GDPR was introduced, many enterprise solutions had to restructure their data handling, just like cities must redesign zoning laws after new environmental policies.
Project Management Hierarchy: How Solutions Are Delivered
Just as cities require multi-layered governance for planning and execution, software and solution development follow a structured project management hierarchy:
|
Management Level |
Urban Planning Equivalent |
Scope & Responsibility |
|
Portfolio Management |
National Development Planning |
Enterprise-wide oversight of all IT initiatives and business-aligned technology investments. |
|
Program Management |
City-Wide Development Initiatives |
Groups multiple projects under one business initiative (e.g., a smart city program integrating transportation, security, and utilities). |
|
Project Management |
Construction of a Single Building |
Focused on one software system or a specific integration project, ensuring timely delivery and alignment with the larger program. |
Takeaway
- Enterprise Software Architecture follows the similar structured approach as city planning.
- High-level stability, middle-layer flexibility, and well-structured execution ensure successful implementation.
- At the bottom, software has a mix of rigidity and flexibility—it allows incremental development, unlike buildings, but some foundational elements (e.g., database schemas) become difficult to change later.
- Like a well-planned city, great software solutions require careful orchestration of strategy, adaptability, and precision.
Plan your IT solutions like you plan a
city—build for the future while remaining adaptable to change!
