I'm not saying AI tooling can't help. But if we're not measuring actual outcomes, we're just confirming our own bias. Start measuring. Compare cycle times, defect rates, rework. Don't let a feeling of speed substitute for evidence of speed.

And make sure you're not feeding the AI hype industry with false promises.

It's hard when method wars between Agile and Six Sigma hide what you're actually building. Simon Wardley shared how mapping a system's evolution helps choose the right approach for each component, avoiding costly failures. Look at the landscape first, then pick your tools.

Hi. I'm Saket from the Netherlands.

He/him.

I believe #kindness is key to our survival.

Fascists, racists, TERFs, misogynists, etc., give me a wide berth (ideally so wide you fall off the edge of your platform into open-mindedness)

I'm interested in conversations with thoughtful conversationalists on topics such as: #books, #writing, #climate, #politics, #philosophy, #banter, #scripting, #apps, #fediverse, #softwaredesign, #martialarts, #ttrpg, #videogames, #design, #devops

#introduction

“I’m writing unit tests because I have to. They just confirm that my code works, which I already know. They are tedious to write, and often stop working when I change the implementation of the system. Maintaining unit tests is often difficult and takes a lot of time out of my day.”

Does this sound familiar? Then you might be interested in my workshop, 𝐖𝐞𝐥𝐥-𝐁𝐚𝐥𝐚𝐧𝐜𝐞𝐝 𝐓𝐞𝐬𝐭-𝐃𝐫𝐢𝐯𝐞𝐧 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭, on 21 𝐚𝐧𝐝 22 𝐌𝐚𝐲 2025 𝐚𝐭 𝐓𝐡𝐞 𝐁𝐫𝐚𝐢𝐧 𝐄𝐦𝐛𝐚𝐬𝐬𝐲 𝐢𝐧 𝐀𝐧𝐭𝐰𝐞𝐫𝐩.

This two-day, hands-on workshop blends theory with practice in a real-world codebase. Yotdd #unittests #softwaredesign #softwarecrafting #xp to master the art of writing loosely coupled and highly maintainable automated developer tests.

Unit tests don't merely run more quickly because they execute a smaller part of the system. They eliminate irrelevant details, which makes spotting the mistake less expensive. #softwaretesting #softwaredesign

Knowing about a bias, it turns out, does not make you immune to it.

I did bring KitKats as a precautionary measure. At least one of us came prepared.

Looking forward to seeing you in Berlin!

First day of another DDD foundation workshop, and we hit the wall that almost every team hits: naming.

Not "what should we call this?" — that's the surface question. The deeper one is: how much does a name already decide for you?

#DomainDrivenDesign #CollaborativeModelling #BoundedContext #SoftwareDesign

We started day 2 of the Tactical DDD training this morning, not with coding, but with discovering and formalising acceptance criteria through Example Mapping. These acceptance criteria then become input for domain modelling with responsibility-driven design through CRC-card modelling.

Developers often see TDD primarily as a testing technique, missing its potential to guide design. @davefarley77 talk showed how shifting focus allows TDD to actively shape software architecture and foster better code structure. It's about using TDD to drive design, not just validate it.

The coloured blocks on the flipchart make it click for most people. Once you can see where coupling creeps in and where boundaries should be, the conversations about architecture become much more productive.

Tomorrow, we go into one of the modules, sketch it out using Responsibility-Driven Design, and then go straight to coding.

A while ago, I was asked whether one should use Inside-Out TDD or Outside-In TDD. At first glance, it might seem important to choose one approach over the other. However, this isn’t the case at all. Inside-Out and Outside-In TDD are not mutually exclusive. There’s no need to rigidly commit to just one. Instead, we should practice and master both approaches to develop an intuitive sense, a *gut instinct*, for when to apply a certain approach. (1/2)

I’m happy to announce my workshop, ‘𝐖𝐞𝐥𝐥-𝐁𝐚𝐥𝐚𝐧𝐜𝐞𝐝 𝐓𝐞𝐬𝐭-𝐃𝐫𝐢𝐯𝐞𝐧 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭’ on 21 𝐚𝐧𝐝 22 𝐌𝐚𝐲 2025 at 𝐓𝐡𝐞 𝐁𝐫𝐚𝐢𝐧 𝐄𝐦𝐛𝐚𝐬𝐬𝐲 𝐢𝐧 𝐀𝐧𝐭𝐰𝐞𝐫𝐩. This two-day, hands-on workshop blends theory with practice in a real-world codebase. You'll be collaborating together with fellow attendees to master the art of writing loosely coupled and highly maintainable automated developer tests.
