Three Key Aspects I Value as an Architect

When considering software architecture, there are standards that I consistently return to.
These are the three axes that help create a robust structure, stabilize the team, and maintain a scalable foundation amidst changes.
Here are the essentials summarized in a memo.

1. Design Standards — The Power of Structural Stability

Fragmentation → Loose Coupling

Breaking down functions into smaller units and defining clear boundaries reduces coupling between modules.
Such a structure enhances replaceability and lowers the risk of failure propagation, making parallel development across teams much easier.

• Single responsibility per module
• Explicit interfaces
• Blocking implicit data sharing

Layering → Flexible Scalability

Separating layers ensures that core Domains remain stable despite external changes (DB, frameworks, UI).
This separation facilitates maintenance, testing, and replacement, and extends the system’s lifespan.

• Separation of roles in Domain / Application / Infra
• Separation of flow and rules
• Adapter-based replaceable structure

2. Single Source of Management — The Benchmark that Unifies the Entire System

Single Source of Truth

When models, schemas, and settings are redundantly defined in multiple locations, changes become unpredictable.
Consolidating these into a single standard can reduce problems by 70%.

• Centralization of common models and types
• Unification of Config / Feature Flag / Locale
• Version management of API and Schema

Blocking Accidental Dependencies

Preventing modules from referencing information they don’t need to know is the essence of architectural quality.

• Removal of unclear imports
• Prohibition of direct references between layers
• Provision of stable Public APIs

3. Workflow Organization — The Structure That Influences Team Productivity

Flow-Based Structuring

As systems grow, Flow becomes the benchmark.
Standardizing common flows like Save Flow, Brew Engine Flow, and Cleaning Flow can exponentially increase team speed.

• Standardization of states and events
• Consistent logic for errors/cancellations/retries
• Sharing identical flows across Front/Back/Device

Eliminating Repetition Through Automation

A structure that avoids wasting time on environmental differences, focusing instead on solving essential problems.

• Standardization of CI/CD pipelines
• Provision of Simulator / Mock / Playground
• Bridging environmental gaps with common CLI and scripts

Conclusion — The Architect’s Three Key Questions

Architecture is less about complex technologies and more about “setting standards and maintaining them.”
If these three axes remain stable, the entire system can grow stably.
