Software Design in the Age of AI: The Art and the Craft

Description

From Coder to Designer: The Art and Science of Building Better Software with AI

AI is transforming software development, making it easier than ever to generate code. But generating code is not the same as designing good software. As AI accelerates coding, the ability to make sound design decisions becomes more important than ever. Software Design in the Age of AI helps students and practicing developers move beyond merely writing code to become thoughtful software designers who can reason about complexity, make informed decisions, and create high-quality, evolvable software systems.

Drawing on decades of research, authors Yuanfang Cai and Rick Kazman bring together foundational design principles and quantifiable techniques that make software design concrete, actionable, and measurable. Through five essential categories of design decisions--components, data, logic, modules, and naming--readers learn to analyze alternatives, manage complexity, and improve software quality. Throughout the book, AI serves as a knowledgeable design partner, helping designers explore alternatives, evaluate tradeoffs, and translate designs into working software while improving quality and productivity.

In this book, readers will learn practical and proven techniques to

• Apply fundamental design principles to make informed decisions about components, data, logic, modules, and naming
• Manage complexity through abstraction, information hiding, and modularization
• Use design rules and the Design Structure Matrix (DSM) to visualize dependencies and build modular, evolvable systems
• Identify design anti-patterns, quantify design debt, and prioritize improvements based on costs and benefits
• Measure and continuously monitor software design quality as systems evolve
• Collaborate with AI to explore alternatives, prototype solutions, evaluate tradeoffs, and critically assess AI-generated designs
• Navigate the essential challenges of software design: context, change, and people

Learn the principles. Master the decisions. Think like a designer.
