Why Self-Contained Systems Are a Perfect Fit for AI-Driven Development

AI is rapidly changing how we build software. Many teams already use AI to generate code, write tests, or analyze changes. Yet, despite all this progress, there is often a feeling[...]

Two Flavors of Spec-Driven Development and Why I Clearly Prefer One

Spec-Driven Development is becoming popular, especially in the context of AI-assisted software development. But when I look at what people mean by it, I see at least two very[...]

Business Use Cases vs System Use Cases

The term “use case” is widely used in software development, but not always consistently. Teams often mix different abstraction levels when writing them, which leads to[...]

Why Spec-Driven Development Can Be Iterative, Incremental, and Agile

Whenever I talk about AIUP and Spec-driven Development, I often hear the same concern: “This sounds like Waterfall.” That reaction is understandable. For many developers,[...]

The Age of ReDevTest: Why Requirements Matter More Than Code

For many years, software development was code-centric. We wrote requirements, then quickly moved to implementation. Tests helped, but code was the real source of truth. AI changes[...]

Why System Use Cases Are Perfect in the Age of AI

AI is changing how we build software. Code, tests, and even UI can be generated very fast. This is powerful, but it also exposes a big weakness in many projects. AI does not[...]

Why Most AI Productivity Gains Are Invisible and How AI Unified Process Changes That

AI is everywhere in software development. Many teams already use AI code assistants daily, and the promises are big: faster development, higher productivity, fewer developers[...]

AI4RE Meets AI Unified Process: Why the IREB Micro-Credential Fits Perfectly

Recently, the AI4RE micro-credential was introduced by International Requirements Engineering Board (IREB). At first glance, it may look like just another certification topic[...]

Stop Starting with Code: Start with System Use Cases

When I work with AI Unified Process, the focus is always on system use cases. They are the core artifact that connects requirements, existing systems, and generated[...]

An AI-Ready Architecture for Business Applications

Agentic AI is changing how we build software. AI is no longer just a helper that writes small code snippets. It can reason about requirements, generate larger parts of a system,[...]

Spec-driven Development is not Task-driven AI

Spec-driven development is suddenly everywhere. Many AI tools claim to support it, and many teams say they are already doing it. But when I look closer, what I often see is[...]

Why User Stories Are a Poor Fit for Spec-Driven Development

User stories are popular in agile teams. They are short, readable, and focused on user value. For many teams, they help with planning and coordination. However, when the goal[...]
