What is spec-driven development? 28.05.2026 45m

Semantic diffusion, combined with the pace of technology change, makes talking about AI-adjacent practices and techniques incredibly diffficult. There are few better examples of this issue than the term 'spec-driven development'. Although it's not new — its coinage precedes our current AI moment — it has become ubiquitous over the last six months or so as software professionals attempt to develop a vocabulary for talking about how they're developing methods for working successfully with coding agents. On this episode of the Technology Podcast, Birgitta Böckeler is joined by Laura Tacho — Developer Experience at AWS — to discuss all things spec-driven development. From competing definitions to different interpretations, implementations and workflows, the discussion provides a frank and grounded look at one of the most discussed and debated terms in modern software engineering.

What is harness engineering? 14.05.2026 40m

'Harness engineering' is one of the most significant terms to emerge in software engineering in 2026. Broadly referring to the work done to control unpredictable AI agents and coding assistants, its use signals growing attention on what needs to be done to make agents reliable and consistent enough for production software in the real-world. On this episode of the Technology Podcast, Birgitta Böckeler joins hosts Prem Chandrasekaran and Nate Schutta to explore what harness engineering actually is, how it should be done and why it should matter to software engineers working today. Having written a number of articles on harness engineering for martinfowler.com based on her experiences with AI-assistance, Birgitta is well-placed to explain the core concepts and implications. Taking in everything from the practices and ideas that pre-date and inform harness engineering to integrating harness engineering into existing workflows, listen for a conversation that will provide much needed clarity on what's an essential topic in the industry.

Anthropic Mythos: Hype, reality and the actual security implications 30.04.2026 48m

Anthropic Mythos garnered significant attention when it was launched in mid-April 2026. Yet despite it apparently presenting an unprecedented threat to global software, you don't have to look to closely to see that this was an effective product launch as much as a story about the grave security risks of today's AI models. But this isn't to say there aren't important implications for software developers, security professionals and other technologists. In this episode of the Technology Podcast, one of our new hosts Nate Schutta is joined by Chris Kramer to discuss Anthropic Mythos and Project Glasswing, unpacking what's hype and what really matters.

Key themes in Technology Radar Vol.34 15.04.2026 44m

In April 2026 we published a new edition of the Thoughtworks Technology Radar — volume 34. Like many recent volumes, this one was dominated by AI. However, while editions over the last couple of years have illustrated the dizzying proliferation of AI-related technologies, vol.34 indicates a degree of evolution in the field, demonstrated by a focus on consistency, reliability and mitigating the collaborative and individual challenges of working with AI. This is reflected in the four themes identified for this Radar: the challenge of evaluating technology in an agentic world; retaining principles, relinquishing patterns; securing permission-hungry agents; putting coding agents on a leash. On this special Technology Radar episode of the Technology Podcast, host Ken Mugrage is joined by Alessio Ferri and Jim Gumbley to discuss the key themes in Technology Radar Vol.34. Diving into topics ranging from cognitive debt, harness engineering and the lethal trifecta, listen to gain a deeper understanding not just of the latest Radar but, more importantly, what AI-assisted and agentic software engineering really look like today.

How it feels to be a software engineer when AI is changing our relationship with code 02.04.2026 41m

There's been a lot of discussion and debate in recent months about exactly how software engineering will be reshaped by AI. While it remains to be seen what the discipline will look like once things quieten down (if they ever do), one thing has been somewhat neglected: what does software engineering actually feel like in this AI-intensive environment? If we're no longer writing code, or even interfacing with it in the way we're used to, what does that mean for our professional experience? On this episode of the Technology Podcast, host Ken Mugrage is joined by Nate Schutta to discuss the software engineering experience today and to dig deep into what the work feels like when AI agents change our relationship with code. Nate is one of the authors of Fundamentals of Software Engineering (alongside Dan Vega) and appeared on the podcast in May 2025 to discuss the book; with so much change having taken place since then, Nate is perfectly placed to offer a perspective on what software engineering means today for an industry navigating significant change.

Durable computing: What is it and why now? 05.03.2026 37m

Managing distributed systems and complex workflows can be challenging. What happens when something fails? If a task isn't executed to completion, that can lead to serious problems. From transaction and billing failures to deploying software, even small issues can have significant consequences. This is one of the reasons for durable computing. Designed to isolate code from crashes, it preserves state so a task is completed even when something fails. To discuss durable computing, explore why it matters today and how we've been using it at Thoughtworks, Brandon Cook and John Coleman join host Alexey Boas on the Technology Podcast. They dive into the current platform ecosystem and what it means for developers — and requires of them. They also talk about the value of durable computing for AI, explaining why the concept of 'durable agents' offers an important of avenue of investigation in a world eager to embrace agentic systems.

Exploring AI agent platforms 22.01.2026 37m

If AI agents really are the future of how work will be done — in software engineering and beyond — the platforms on which they are built, run and maintained will be crucial. This is a topic two Thoughtworkers, Ben O'Mahony and Fabian Nonnenmacher, are currently writing about. Although not due to be published until early 2027, the first two chapters of Building AI Agent Platforms are now available as part of O'Reilly's Early Release scheme. Its goal is to provide readers with a complete roadmap for developing AI agent platforms, from agent development to architectural principles to observability and governance. In this episode of the Technology Podcast, the authors speak to regular host Ken Mugrage about the book, why agent platforms are a critical part of any AI strategy and some of the challenges of developing and maintaining them. Listen for an early look at what looks set to be a valuable book in the world of AI development and to gain a clearer perspective on what agentic AI really means at the start of 2026.

Architecture antipatterns and pitfalls: Good intentions, bad habits and ugly consequences 08.01.2026 35m

You can grasp the basics of software architecture by learning design patterns, but you probably won't master it — to do that you have to get to grips with antipatterns too. Often these lessons are hard-won through experience, derived from seeing what happens when architectural decisions (or the lack of them) collide with the messy reality of the real world. While there's obviously no replacement for practical experience, Neal Ford, Mark Richards and Raju Gandhi want to share theirs to give architects the opportunity to avoid common antipatterns and pitfalls and make smarter decisions. That's what they're doing with their forthcoming book (due September 2026) Architecture Patterns, Antipatterns and Pitfalls. On this episode of the Technology Podcast, host Neal is joined by his co-authors and their editor from O'Reilly, Sarah Grey, to discuss the book and to explore why getting to know on antipatterns and pitfalls matters as much as learning design patterns. Learn more about Software Architecture Patterns, Antipatterns and Pitfalls: https://www.oreilly.com/library/view/software-architecture-patterns/0642572221119/ Listen to Neal and Mark discuss the various intersections of software architecture on an episode of the Technology Podcast from 2025: https://www.thoughtworks.com/insights/podcasts/technology-podcasts/exploring-intersections-software-architecture

Are we entering the 'age of intent' in digital interaction? 23.12.2025 45m

The 'age of intent' is a phrase that's been around for a number of years. However, with the rise of AI agents in 2025 it has the potential to become a key trend for 2026. It describes a new way of thinking about digital interaction in which the gap between human intention and output are reduced even further through AI assistance. Thoughtworks' APAC CTO Sarah Taraporewalla has been exploring the age of intent in recent months; she's written a series of blog posts that tackle what this new phase of digital interaction means for businesses and how they can prepare themselves. On the latest episode of the Technology Podcast, Sarah joins host Lilly Ryan to discuss the concept the age of intent and its implications for the future of digital experiences.

We still need to talk about vibe coding: Reflections on 2025's word of the year 27.11.2025 46m

Vibe coding was, remarkably, named word of the year by the Collins English Dictionary at the start of November 2025 — pretty good going for a term that was only coined in February. We first discussed it on the Technology Podcast back in April, and, given its prominence in the collective lexicon this year, thought we should revisit and reflect on the topic as 2025 draws to a close. Lots has happened in the intervening months: MCP adoption, the evolution of agentic coding tools and practices like context engineering have had a significant impact on the way the world is thinking about and using AI. To talk about it all and reflect on the implications, Thoughtworkers and regular podcast hosts Prem Chandrasekaran, Lilly Ryan and Neal Ford reconvened for a follow up to our April conversation. Taking in everything from the term's semantic slipperiness, its security risks and the challenges of maintaining AI-generated code, this is a discussion that, despite going deep into vibe coding, also touches on a huge range of issues in the technology industry today. Before we enter 2026, looking back on the good, the bad and the ugly of the last 12 months of experimentation is essential if we're to build better software for the world in the future. This episode aims to be a guide through that process.

What we're talking about when we talk about context engineering 02.10.2025 20m

Everyone seems to be talking about context engineering. That was certainly the case in our recent discussions for the upcoming edition of the Technology Radar (volume 33, due early November 2025). And although we ran into the term on the Technology Podcast just a few weeks ago, we thought it would be useful to try and tackle exactly what people are talking about when they talk about context engineering. We know context is important when it comes to AI, but what does it mean to engineer it? On this episode of the Technology Podcast, host and Thoughtworks CTO Rachel Laycock is joined by Thoughtworkers Alessio Ferri (Lead Software Engineer) and Bharani Subramaniam (CTO for India and the Middle East) to discuss what context engineering is, how it's being done and what it tells us about the evolution of AI. This certainly won't be the last word — ours or anyone else's — on context engineering, but it might help clarify and cement your understanding as the term comes to dominate technology conversations.

Mean time to shared understanding: Bridging the gap between citizen developers and developers 18.09.2025 28m

Although the concept of the 'citizen developer' isn't new, with the rise of AI the relationship between those building software without much technical experience and seasoned software developers is becoming more significant. That's not to say there's conflict exactly, but there are often competing interests and demands — which can lead to tension, organizational friction and governance challenges. On this episode of the Technology Podcast, host Ken Mugrage facilitates a debate (of sorts) between Christopher Hastings, Global Tech Product Lead at Thoughtworks (and citizen developer) and Scott Davies, Head of Technology for Thoughtworks Europe (very much in the developer camp). They discuss the needs and interests of both sides, how to avoid regressing to the dark ages of shadow IT and how citizen developers can be properly empowered by engineering teams.

Organizational design and Team Topologies after AI 04.09.2025 42m

Managing technological change in an organization — particularly a large and complex one — has always been challenging. But thanks to the rapid adoption of AI in all kinds of spheres, from knowledge management to software development to content creation, it's becoming more difficult than ever. How do you strike a balance between governance and safety and autonomy and empowerment? How should teams be structured and how should they work together? In this episode of the Technology Podcast, Matthew Skelton and Manuel Pais — authors of the influential Team Topologies book — join hosts Birgitta Böckeler and Ken Mugrage to discuss what AI means for organizational design. They discuss how AI is changing team capabilities, what it means for cognitive load and knowledge sharing and how to ensure there's structure and control without constraining experimentation and creativity. With the second edition of Team Topologies set to be published in September 2025, Matthew and Manuel used the conversation to explore the evolution of their ideas and what they've learned from working with and listening to the stories of many different organizations around the world.
