Defining software architecture as the important, hard-to-change decisions

Software architecture is the shared understanding of system design decisions that are difficult to change later, encompassing both technical and people-related aspects.

Why a software architect is more like a town planner

The town planner analogy better captures the architect's role of managing an evolving system with long-term business goals in mind, unlike the static house-building analogy.

How poor internal quality slows down development over time

Martin Fowler's Design Stamina Hypothesis illustrates how investing in good internal design initially pays off by enabling faster feature delivery in the long run.

Understanding and managing the impact of technical debt

Technical debt accumulates like a messy kitchen or a bad game of Tetris, slowing down all future work until it is addressed and paid down.

Isolating business logic with the hexagonal architecture pattern

The hexagonal architecture pattern uses ports and adapters to isolate the core application logic from external dependencies like databases and user interfaces.

Using modular design to isolate the consequences of decisions

By isolating functionality into separate components, you can strategically accept technical debt, contain the blast radius of failures, and safely experiment with new features.
