We need to talk about vibe coding

The term 'vibe coding' — which first appeared in a post on X by Andrej Karpathy in early February 2025 — has set the software development world abuzz: everyone seems to have their own take on what it is, how it's done and whether it's a bold new chapter in the history of programming or an insult to anyone that's ever written a line of code. Clearly, then, we need to talk about vibe coding — and that's precisely what we do on this episode of the Technology Podcast. Featuring Thoughtworkers Birgit...

How fitness functions can help us govern and measure AI

AI is inherently dynamic: that's true in terms of the field itself, and at a much lower level too — models are trained on new data and algorithms adapt and change to new circumstances and information. That's part of its power and what makes it so exciting, but from a business and organizational perspective, that can make governance and measurement exceptionally difficult. How can we know that our AI is optimized for the right thing? How can we be sure it's oriented towards what we want it to be?...

Who should make software architecture decisions?

Who should be involved in the process of making decisions about software architecture? That's a question that's been puzzling Thoughtworker Andrew Harmel-Law for some time — so much so that he decided to write a book about it. The result is Facilitating Software Architecture . Published by O'Reilly in December 2024, it's both an argument for and a guide to involving more people in the architecture decision process. To discuss the topic and the book, Andrew joined hosts Neal Ford and Prem Chandra...

Software service granularity: Getting it right

It's widely accepted that, in most cases at least, software systems should be modular, consisting of separate, discrete services. But what about the size of those services? How big or small should they be? This is where the question of service granularity comes in: too small and your system will become needlessly complicated; too big and you lose all the benefits of modularity you were seeking in the first place. In this episode of the Thoughtworks Technology Podcast, host Ken Mugrage is joined ...

Sensible defaults: A way to think about our technology practices

If you work in technology, you're constantly making decisions: not just what you should do, but also how you should do it. That's why we developed the concept of "sensible defaults" — practices and technology decisions that we generally see — in most scenarios — as the right way to do things. Although we've been talking about sensible defaults internally for a few years now, we recently decided to share them publicly on our website. We did so because we believe it can help organizations think th...

Continuous delivery vs. continuous deployment: What should be the default?

Despite occasional confusion, the difference between continuous delivery and continuous deployment is simple: should deploying to production be on demand or every good build? Answering which approach is 'best' is difficult; any attempt at dogmatism is likely to just look foolish, given it is, like many other debates in software development, context-dependent. But that doesn't mean we shouldn't try and unpick the issues at the heart of the discussion. It's all well and good saying the debate is c...
