I was interviewed on the Book Overflow podcast about the Refactoring book. We talked about the origins of the book, the relationship between refactoring, testing, and extreme programming, how refactoring is used in the wild, and the role of books and long-form prose today. more…

Alessio Ferri, Tom Coggrave, and Shodhan Sheth complete their article on what they have learned from using GenAI with legacy systems. They describe how GenAI's ability to process unstructured information makes it much easier to build a capability map of a legacy system, tying the capabilities of a system to...

Alessio Ferri, Tom Coggrave, and Shodhan Sheth use their combination of an AST-fueled knowledge graph and LLMs to gain understanding of legacy systems. They have found it aids them both in extracting the low-level details of the code and can provide high-level explanations to support human-centered approaches...

Most of the talk about the impact of GenAI on software development is about its ability to write (messy) code. But many of us think it's going to be much more useful to help us understand existing messy code, as part of a modernization effort. My colleagues Alessio Ferri, Tom Coggrave, and Shodhan Sheth have...

Decentralized data management requires automation to scale governance effectively. Fitness functions are a powerful automated governance technique my colleagues have applied to data products within the context of a Data Mesh. Since data products serve as the foundational building blocks of a data strategy, ensuring...

Cycle Time is a measure of how long it takes to get a new feature in a software system from idea to running in production. In Agile circles, we try to minimize cycle time. We do this by defining and implementing very small features and minimizing delays in the development process. Although the rough notion of cycle time, and the importance...
