About this training

Agile Kitchen is iLean’s free, quarterly community event for people who care about Agile in practice – not just in theory.

Each edition dives into a real-world topic that Agile teams wrestle with every day: from team dynamics and product decisions to leadership challenges and organisational change. You won’t find lectures or sales pitches here – just thoughtful, hands-on sessions where practitioners share what works (and what doesn’t) in their context.

About this event

Apollo put twelve people on the moon in three and a half years, and then it stopped. We're still trying to get back, and it turns out the hard part was never the rockets. The engineers retired. The suppliers closed. The blueprints survived, but the thousand small judgments that made them work were never written down. At the time, everybody simply knew them.

That's what losing knowledge looks like. No decision, no disaster. Just a slow drain you don't notice until you try to do the thing again and find you can't.

Now look at your own team. All the buzzwords are still there: pair programming, test-driven development, refactoring and continuous integration. People sit in open-plan offices wearing headphones 90% of the time. Tests that were supposed to design the code are written afterwards, if there's time. Technical debt is spinning out of control. Refactoring sprints anyone? Senior developers write comments on pull requests, thinking that this is what coaching others is all about.

Extreme Programming gave our industry a set of practices that made genuinely good software possible, and we're quietly forgetting them while still using their words.

‍

First, what is Extreme Programming?

XP is an Agile approach from the late 1990s, born around the same time as Scrum. The difference is worth knowing: Scrum describes how a team organizes its work, XP describes how a team actually builds the software. Short cycles, and a handful of practices that keep the code healthy enough to keep changing it: pair programming, test-driven development, continuous integration, refactoring, small releases.

Together they answer a question Scrum never really addresses: what does it take for a team to still be able to change direction in year three?

Agenda

Agile Kitchen is our quarterly gathering, where you can reflect, recharge, and enjoy meaningful conversations. Bring your curiosity, and leave feeling inspired and eager to try something new.

Why join this event

Jan Van Ryswyck takes us back to where XP came from, what problems it was actually built to solve, and what each of its core practices was really meant to do. Not as history for its own sake, but so you can recognize the watered-down version when you're living inside it.

  • You will understand where Extreme Programming came from and which real problems it was built to solve.
  • You will walk through each core practice and see the value it delivers, rather than what the ritual has become.
  • You will be able to spot the diluted version of a practice in your own team, and put words to what's missing from it.
  • You will understand how technical practices and team agility are connected, which makes for far better conversations with the developers you work with.
  • You will leave with a sense of where to take these practices next, in your context and with your constraints.

A real understanding of XP pays dividends for the rest of your career, whether you build software or help teams build it well. This session gets you started.

Topics we'll cover

True to the Agile Kitchen spirit, this is a session with room to talk back. Jan brings two decades of hands-on practice rather than a slide deck of theory.

  • The origin story: Where XP came from and which problems it set out to solve.
  • The practices: Each core practice, what it's worth, and where it goes wrong.
  • The exchange: Open discussion and Q&A grounded in your context, not a generic one.

‍

What’s included

  • It’s free, interactive, and community-driven
  • We keep it practical, open, and refreshingly no-nonsense
  • You’ll connect with curious minds who think critically and share generously
  • And yes, there’s always food. And real conversation.
