Decoding DeepSeek Feb 06, 2025

The release of DeepSeek's AI models at the end of January 2025 sent shockwaves around the world. The weeks that followed have been rife with hype and rumor, ranging from suggestions that DeepSeek has completely upended the tech industry to claims the efficiency gains ostensibly unlocked by DeepSeek are exagerrated. So, what's the reality? And what does it all really mean for the tech industry?

In this episode of the Technology Podcast, two of Thoughtworks' AI leaders — Prasanna Pendse (Global Director of AI Strategy) and Shayan Mohanty (Head of AI Research) — join hosts Prem Chandrasekaran and Ken Mugrage to provide a much-needed clear and sober perspective on DeepSeek. They dig into some of the technical details and discuss how the DeepSeek team was able to optimize the limited hardware at their disposal, and think through what the implications might be for the industry in the months to come.

AI testing, benchmarks and evals Jan 23, 2025

Generative AI's popularity has led to a renewed interest in quality assurance — perhaps unsurprising given the inherent unpredictability of the technology. This is why, over the last year, the field has seen a number of techniques and approaches emerge, including evals, benchmarking and guardrails. While these terms all refer to different things, grouped together they all aim to improve the reliability and accuracy of generative AI.

To discuss these techniques and the renewed enthusiasm for testing across the industry, host Lilly Ryan is joined by Shayan Mohanty, Head of AI Research at Thoughtworks, and John Singleton, Program Manager for Thoughtworks' AI Lab. They discuss the differences between evals, benchmarking and testing and explore both what they mean for businesses venturing into generative AI and how they can be implemented effectively.

Exploring the intersections of software architecture Jan 09, 2025

Software architecture necessarily intersects with a diverse range of critical things, including implementation, infrastructure, data and engineering practices. All these elements require serious consideration and reflection if you're to architect effectively.

To discuss these various intersections, Thoughtworks' Neal Ford and his long-time collaborator Mark Richards join host Prem Chandrasekaran on the Thoughtworks Technology Podcast. They dive into why these intersections matter, what they mean for software architects and how individuals and teams can go about addressing them.

Who should make software architecture decisions? Dec 26, 2024

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 Chandrasekaran on the Technology Podcast. They explore why including more roles in software architecture matters today, some of the common objections to and risks of such an approach, alongside techniques and practices that can make doing it in fast-paced and dynamic organizations easier.

"It's quite magical when you see this blossoming of understanding of what it is that architects do... It's not less architecture, it's more. It's just happening in a broader sphere." — Andrew Harmel-Law

Generative AI's uncanny valley: Problem or opportunity? Dec 12, 2024

With the rise of generative AI, the concept of the uncanny valley — where human resemblance unsettles, disturbs or disgusts — is more relevant than ever. But is it a problem that technologists need to tackle? Or does it offer an opportunity for greater thoughtfulness about the ways generative AI is being built, deployed and used?

In this episode of the Technology Podcast, host Lilly Ryan is joined by Srinivasan Raguraman to discuss generative AI's uncanny valley and explore how it might offer a model for thinking through our expectations about generative AI outputs and effects. Taking in everything from the experiences of end users to the mental models engineers bring to AI development, listen for a wide-ranging dive into the implications of the uncanny valley in our experience of generative AI today.

Using generative AI for legacy modernization Nov 28, 2024

Legacy modernization is an enduring challenge — and as systems become more complex, the difficulty of understanding and modelling a system so it can be modernized only becomes more difficult. However, at Thoughtworks we've seen some recent success bringing generative AI into the legacy modernization process.

To discuss what this means in practice and the benefits it can deliver, host Ken Mugrage is joined by Thoughtworks colleagues Shodhan Sheth and Tom Coggrave. Shodhan and Tom have been working together in this space in recent months and, in this episode of the Technology Podcast, offer their insights into finding success with this novel combination. They explain how it can be implemented, the challenges and experiments they did on their way to positive results and what it means for how teams and organizations think about modernization in the future.

Data contracts: What are they and why do they matter? Nov 14, 2024

Data contracts are a bit like APIs for data — they make it possible to interface with data in a way that ensures the transfer of data from one place to another is stable and reliable. This is particularly important for building more reliable data-driven applications.

To discuss data contracts, host Lilly Ryan is joined on the Technology Podcast by Andrew Jones, the creator of the data contract concept (in 2021) and author of Driving Data Quality with Data Contracts (2023), and Thoughtworker Ryan Collingwood who is currently writing their own book on data contracts due to be published in 2025. Andrew and Ryan offer their perspectives on the topic, explaining the origins and motivation for the idea and outlining how they can be used in practice.

Themes from Technology Radar Vol.31 Oct 17, 2024

Volume 31 of the Technology Radar will be released on October 23, 2024. As always, it will feature 100+ technologies and techniques that we've been using with clients around the world. Alongside them will be a set of key themes that emerged during the process of putting it together. We think they offer another way into the Radar and give a unique insight on some of the most interesting issues impacting the software industry.

In this episode of the Technology Podcast we discuss them: coding assistance antipatterns, Rust being anything but rusty, the rise of WebAssembly and what we describe as the "cambrian explosion of generative AI tools." To do so, Alexey Boas is joined by guests and podcast regulars Ken Mugrage and Neal Ford. Ken and Neal provide an insight into the conversations that happened during the process, and offer their perspective on the implications of these themes for the wider tech industry.

Build Your Own Radar: Using the Technology Radar as a governance tool Oct 03, 2024

The Thoughtworks Technology Radar is, first and foremost, a publication. It's a document that anyone in the tech industry can read twice a year to learn about our experiences and perspectives on technology. However, it's also more than that: it's built on top of a process of deliberation, discussion and curation. We think that's particularly important — it's something we encourage technology teams and organizations to do and which we support with our Build Your Own Radar tool.

On this episode of the Technology Podcast, Neal Ford and Ken Mugrage join Prem Chandrasekaran to discuss Build Your Own Radar. They outline why the Radar process is just as important as the artifact that gets created at the end, and explain how organizations can use it to facilitate conversations about how and what technology they use and want to use in the future.

Exploring DuckDB: A relational database built for online analytical processing Sep 19, 2024

There are no shortage of options when it comes to relational databases. While the likes of PostgreSQL have proven enduring, even as the market has evolved, for data scientists and data engineers that need to manage and query particularly complex or large data sets, the most popular databases aren't always right for the job. Thankfully, this is where projects like DuckDB can help. Built for what's called 'vectorized query execution', it's well-suited to the demands of online analytical processing (OLAP).

To get a deeper understanding of DuckDB and how the product has developed, on this episode of the Technology Podcast, hosts Ken Mugrage and Lilly Ryan are joined by Thoughtworker Ned Letcher and Thoughtworks alumnus Simon Aubury. Ned and Simon explain the thinking behind DuckDB, the design decisions made by the project and how its being used by data practitioners in the wild.

Software service granularity: Getting it right Sep 05, 2024

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 by Neal Ford and Mark Richards — authors of multiple books on software architecture — to discuss service granularity. They explain why it matters and how software architects can go about getting it right, through the lens of granularity integrators and disintegrators.

How can AI support designers? Aug 08, 2024

Artificial intelligence has been presented as a technology with the potential to transform many different fields and professions. One of the most notable is design — but if we want to design in a way that's truly human-centric and inclusive, to what extent can artificial intelligence really help us do better work?

In this episode of the Technology Podcast, hosts Rebecca Parsons and Lilly Ryan speak to Thoughtworks design leaders Kate Linton and Esther Tham to get their perspective on how AI might be able to support designers. They discuss what AI tools could help the design process, how these tools could fit neatly into current practices and what the emergence of this technology could mean for design practices more broadly.

Sensible defaults: A way to think about our technology practices Jul 25, 2024

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 through their own approach to technology decision-making, something which is becoming increasingly challenging in a rapidly changing and complex world.

So, to discuss sensible defaults and explain precisely why we want to share them with the world, hosts Rebecca Parsons and Ken Mugrage are joined by Brandon Cook and Kief Morris, two Thoughtworkers that played an important role in putting our sensible defaults together. They discuss the origins of the sensible default idea, some examples, as well as the challenges of putting them into practice.

Tracking technology stacks, practices and experiences across teams Jul 11, 2024

Understanding your technology estate and how it's being leveraged is critical for organizations; it impacts everything from financial planning to capability development. But given the rapid pace of change — even inside a single company, let alone the wider industry — how can this be done effectively? One approach we've landed on at Thoughtworks is something called a Tech Dash: it's a method of internal research that surfaces information about an organization's technology use, and even software developers' experiences.

In this episode of the Technology Podcast, Camilla Crispim and Renan Martins talk to hosts Alexey Boas and Ken Mugrage about the value of a Tech Dash and explain how it can help track technology use. They also discuss where the idea came from and how they put it into practice across Thoughtworks Brazil.

Inside Bahmni: An open-source digital public good Jun 27, 2024

Bahmni started life as an open-source hospital information management system and electronic medical record for a single hospital in rural India. Today, it has more than 500 implementations in 50 countries across Africa and Asia, and is recognized as one of only 165 digital public goods by the Digital Public Goods Alliance.

Thoughtworks played a key part in bringing Bahmni into the world back in 2012. And although today it’s run and supported by a coalition of organizations, Thoughtworks continues to have a leading role in the project as a member of its Governing Committee.

To tell Bahmni’s unique story, Rebecca Parsons and Ken Mugrage speak with Satish Viswanathan and Angshuman Sarkar, two Thoughtworkers actively participating and contributing to the project. They discuss Bahmni’s origins and how it grew from a small, local tool to become a vital component in healthcare infrastructure in parts of the world that have long faced resource challenges.

How to assess your organization's security maturity Jun 13, 2024

One of the fundamentals of security is self-awareness: knowing where you may be vulnerable, the practices and processes that aren't yet quite in place and what actions you need to prioritize are essential if your organization is to excel at security. But how can that be done? In complex and distributed teams, surfacing such knowledge can be incredibly difficult. One solution, though, is something called a security maturity model.

In this episode of the Thoughtworks Technology Podcast, Thoughtworks alumnus Diana Adorno and current Thoughtworkers Lisa Junger and Robin Doherty speak to host Alexey Boas about a security maturity model they've developed that was recognized by the prestigious CSO50 Awards. They explain the purpose of developing and using one, how theirs works and why it should matter to any organization that wants to get serious about the way it does security.

Continuous delivery vs. continuous deployment: What should be the default? May 30, 2024

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 context-dependent, but what does that actually mean in practice?

In this episode of the Technology Podcast, Ken Mugrage and Valentina Servile debate the merits of both continuous delivery and continuous deployment. Talking with hosts Prem Chandrasekaran and Birgitta Böckeler, they offer their perspectives on when and where both should be used — in making the case for their chosen approaches, they shed some much needed light on a discussion that every software engineering team should have.

Diving head first into software architecture Mar 07, 2024

A few years ago, Thoughtworker and (prolific) author Neal Ford published Fundamentals of Software Architecture with Mark Richards. They're now back with another book on software architecture — written with co-author Raju Gandhi — which offers readers a very different learning experience. Described as a combination of technical book and graphic novel, Head First Software Architecture dispenses with dense prose to present and explain software architecture concepts and ideas in some highly innovative and novel ways.

In this episode of the Technology Podcast, the authors — alongside their editor, Sarah Grey — join Rebecca Parsons to discuss their new book. They explain the thinking behind the approach, how it diverges from Fundamentals of Software Architecture and detail some of the challenges of writing in a new format.

Whether you're interested in getting started with software architecture or simply curious about technical communication and learning, listen to find out more.

Exploring the building blocks of distributed systems Feb 22, 2024

Distributed systems are ubiquitous yet complex. They can be particularly demanding for software developers and architects tasked with dealing with the sometimes unpredictable nature of the interactions between their various parts.

That's why Thoughtworker Unmesh Joshi wrote Patterns of Distributed Systems. Published at the end of 2023, the book explores a number of patterns that characterize distributed systems, and uses them to not only help readers better understand how such systems work but also to solve problems and challenges that often arise.

On this episode of the Technology Podcast, Unmesh joins hosts Scott Shaw and Rebecca Parsons to talk about his book, explaining where the idea came from, how he put it together and why it's important to get beneath neat abstractions to really get to grips with the inner workings of distributed systems.

Software-defined vehicles: The future of the automotive industry? Feb 08, 2024

A few decades ago, it would have probably seemed strange to put software and automobility together. However, today software is embedded in all kinds of modern vehicles, enabling capabilities in everything from driving to passenger entertainment. But what exactly does this all mean for the automotive industry? And what demands does it place on design and manufacturing processes?

In this episode of the Technology Podcast, two Thoughtworks experts on software-defined vehicles — Michael Fait and Sriram J. — speak to Ashok Subramanian and Ken Mugrage about how the automotive industry has been changed by software. They cover everything from the implications software has for the way we think about design, manufacturing and regulation across the industry to the skills and practices developers need to work in this exciting space.

Beyond the DORA metrics: Measuring engineering excellence Jan 25, 2024

Is it really possible to measure the impact engineering teams have on a business' success? At a time when growth is challenging for many organizations and questions about productivity and effectiveness dominate industry conversations, getting it right is crucial. And although the DORA metrics are today well-established and extremely useful is it really enough? Do they actually help us tie the work we do to tangible business results?

In attempting to answer these questions, a group of Thoughtworkers have developed what they call EEBO metrics. These are designed to measure engineering excellence to business outcomes.

To discuss EEBO metrics, hosts Prem Chandrasekaran and Scott Shaw (CTO, Thoughtworks APAC) are joined by Dinker Charak (Principal Product Strategist) and Sachin Dharmapurikar (Global Product Manager). Charak and Dharmapurikar helped to develop EEBO metrics; they believe it can be a valuable tool in aligning often complex engineering projects and activities with high-level business goals and objectives. Listen as they explain what EEBO metrics are (and aren't) and how businesses should think about using them.

Asynchronous collaboration: Getting it right Jan 11, 2024

Thanks to the pandemic, asynchronous working is, today, fairly common. However, it's often easily confused with simply working remotely — and while there are certainly neat synergies between the two, asynchronous working isn't just a description of your working arrangement: it's a set of intentional practices and artifacts that allow people to work together without having to physically be together.

On this episode of ther Technology Podcast, Thoughtworkers Sumeet Gayathri Moghe — author of The Async-First Playbook — and Maya Ormaza join hosts Neal Ford and Ken Mugrage to offer their perspectives on asynchronous working. Taking in everything from the value of written communication, work that demands synchronicity and the importance of leadership to async working, listen to gain a fresh perspective on the way we work together in 2024.

In the most recent edition — volume 29, published in September — we picked out AI-assisted software development, the challenges of measuring productivity, the rapid growth of LLMs and remote delivery workarounds beginning to mature in a post-pandemic world.

For this, the final Technology Podcast episode of 2023, a few members of the team involved in putting the Technology Radar together — Neal Ford, Rebecca Parsons, Scott Shaw and Erik Doernenberg — got together to discuss these themes in more detail and offer their perspectives. As we leave the year behind, it's a great way to review some of the key issues and stories that shaped the way the world builds software.

Leveraging generative AI at Bosch Dec 14, 2023

Generative AI has, unsurprisingly, been a major topic of conversation within Thoughtworks in 2023. However, as enjoyable as it is to get sucked into discussions about the reality, the risks and the benefits of this new technology, what's really interesting — and most important — is understanding how organizations can actually leverage generative AI in a way that's both safe and effective.

For this episode of the Technology Podcast, Rebecca Parsons and Birgitta Böckeler spoke to Andreas Nauerz, CTO and Executive Vice President of Bosch Digital, who explained how he and his team have been thinking about generative AI and exploring the ways it can be leveraged across a huge multinational organization. He discusses where generative AI has already been effective, managing risk and the challenges of bring a large organization with you as you seek to implement something new.

Jugalbandi: Building with AI for social impact Nov 30, 2023

It's easy for key industry players to talk up AI's potential positive social impact, but what does building for social impact actually look like? At Thoughtworks, a small team has been working on a project called "Jugalbandi," designing AI-driven systems and tools for civil society initiatives, such as a chatbot that helps Indian citizens find information about government programs and schemes in their native language. Earlier this year, Jugalbandi caught the attention of Microsoft CEO Satya Nadella, who saw it as evidence of AI's power to drive transformative change to every single part of the world.

In this episode of the Technology Podcast, Jugalbandi team members Vinod Sankaranarayanan and Prathamesh Kalamkar offer an inside look at the project, talking in detail about the work they've done, some of the challenges they've faced and how they're looking to expand and increase its impact in the months and years to come.

AI-assisted coding: Experiences and perspectives Nov 16, 2023

Generative AI appears to be making an impact in a huge range of fields, but one that we're particularly interested in at Thoughtworks is its use in software development.

In recent months, there's been a lot of talk in the industry around issues like whether AI might boost developer productivity and if it can be used for pair programming, but in this episode of the Technology Podcast we try to get beneath the hype to explore the reality of generative AI and software development — how is it actually being used today? What works? And what doesn't?

To dive deeper into all this, Chief of AI Mike Mason and Global Lead for AI-Assisted Software Delivery Birgitta Böckeler join hosts Prem Chandrasekaran and Neal Ford, discussing everything from the current tooling to the way GenAI is shaping developer practices and workflows.

What's it like to maintain an award-winning open source tool? Nov 02, 2023

Open source contributors and maintainers play a vital role in the technology ecosystem. But what's it like to develop and maintain an open source tool — especially one that thousands of other developers use and depend on?

In this episode of the Technology Podcast, Srinivasan Sekar and Sai Krishna join hosts Rebecca Parsons and Scott Shaw to discuss their work on AppiumTestDistribution, an open source tool that supports test automation framework Appium. AppiumTestDistribution won a LambdaTest Delta Award at the August 2023 Testμ Conference.

Listen to Sekar and Krishna explain how the project emerged, how they approach maintaining and evolving the tool and what it takes to be a part of an award-winning open source project.

Engineering platforms and golden paths: Building better developer experiences Oct 19, 2023

The weaponization of complexity Apr 20, 2023

We often describe our high-tech and digitally mediated world as "complex" but we rarely spend much time considering how that complexity can be cleverly deployed as a means of duping or manipulating us. However, trends like NFTs have brought this into clearer view. This is not to say it's a novel phenomenon — from dark patterns in UX design to pages and pages of end-user license agreements (EULAs), leveraging complexity for nefarious ends has long been an unsavory aspect of the technology industry.

In this episode of the Technology Podcast, Mike Mason and Neal Ford are joined by Thoughtworks designer Kate Linton and Thoughtworks North America Head of Legal Jeremy Gordon to discuss what they describe as "the weaponization of complexity." Together, they grapple with the cynicism at the center of such activities and discuss some of the ways we can tackle it.

How we put together the Technology Radar Apr 06, 2023

The Thoughtworks Technology Radar is a snapshot of technologies and practices that the company believes the industry should be interested in, based on the actual experiences of Thoughtworkers working with clients. With its first edition launched in January 2010, it is now a fixture of the Thoughtworks calendar, released twice a year in the spring and fall.

Although it has been around for more than a decade, we're well aware that people have lots of questions about it. One comes up more than others: how do you actually put it together? Giving a good, short answer is difficult — for those involved, it's a long process involving various stages of writing, debate and deliberation.

However, with the next edition of the Radar — volume 28 — just weeks away, we wanted to give the world an insight into how we put Technology Radar together. In this episode of the Technology Podcast, Marisa Hoenig, Perla Villareal and Camilla Crispim join host Neal Ford to discuss the work that goes into producing it and what the experience is like.

Reckoning with the force of Conway's Law Nov 03, 2022

While putting together this year's Technology Radar, Conway's Law — the idea that organizations are constrained to produce systems that mirror their communication structures — was the subject of a lot of discussion. Should we fight it — by deploying the inverse conway maneuver? Or do we need to adopt a more nuanced approach and consider how we can leverage it?

In this episode of the Technology Podcast, Martin Fowler and James Lewis join hosts Birgitta Böckeler and Mike Mason to delve into Conway's Law. They explore what Conway's Law means for organizations today, how it should — and should not — be applied and why everyone working in and around software systems needs to pay close attention to it.

Read the 1968 paper (by Melvin Conway) that identified the phenomenon.

Exploring the Basal Cost of software Oct 20, 2022

The “Basal Cost” of software is an idea from Eduardo Ferro Aldama. The term is borrowed from biology, where the "Basal Metabolic Rate" refers to the number of calories a human body burns just to maintain normal functioning. Applied to software development, the concept is intended to help us pay much more attention to the long term costs — like additional complexity and maintenance — of building a new feature.

In this episode of the Technology Podcast, James Lewis and Georgina Giannoukou join hosts Neal Ford and Birgitta Böckeler to discuss the Basal Cost of software and explore how it can help organizations and software development teams better manage product and system complexity.

Why full-stack testing matters Oct 05, 2022

The hard parts of software architecture Oct 07, 2021

In today’s modern distributed systems are by their very nature complex. The decisions you need to make — around the wiring of your services, what size should the services be, and how should they call one another — are uniquely complex. In Software Architecture: the hard parts, the authors explore the rough edges of software architecture and look at how you can effectively do trade analyses that work for you. We catch up with two of the book’s co-authors.
