What are non-functional requirements (NFRs)?

NFRs, also known as quality attributes or '-ilities', describe how a system performs (e.g., speed, security, scalability) rather than the specific features or functions it provides.

Can I use this skill for system design interview preparation?

Yes, it provides structured templates, checklists, and industry-standard definitions that are essential for successfully navigating system design interview questions.

How do I make quality attributes measurable?

The skill provides a specific template for 'Quality Attribute Scenarios' which includes a source, stimulus, artifact, environment, response, and a specific measure of success.

How does this skill help with architectural trade-offs?

It identifies common architectural conflicts, such as the trade-off between performance and consistency or security and usability, allowing you to make data-driven design decisions.

What standards does this taxonomy follow?

The skill incorporates the ISO 25010 Quality Model along with modern cloud-native architectural patterns for scalability, availability, and resilience.

クラウドインフラストラクチャ

Provides a comprehensive framework for defining, evaluating, and implementing non-functional requirements and architectural trade-offs.

概要

This skill empowers developers and architects to systematically address non-functional requirements (NFRs) such as scalability, reliability, and security during the system design process. It offers a structured taxonomy based on industry standards like ISO 25010, helping teams identify critical trade-offs, define measurable quality scenarios, and apply specific architectural tactics to meet complex business objectives. Whether you are conducting an architecture review or preparing for a system design interview, this skill ensures no quality dimension is overlooked.
