Based on my MBA research, this talk explores the current state of Agile adoption in Greek organizations. Drawing on survey data from executives and Agile team members, it examines how Agile is practiced today, which frameworks are in use, what success looks like and where things quietly start to break down. The research reveals a growing gap between how leaders believe Agile is working and how teams actually experience it. Using a data-driven lens, we explore the real challenges of scaling Agile in Greece, the underestimated role of culture and people, and what it takes to build truly adaptive, innovation-driven organizations. While the data was collected in Greece, the findings are compared with some of Europe’s most mature Agile environments, particularly Denmark and the Netherlands. This comparison places the Greek ecosystem in a broader EU context, distinguishing local constraints from universal Agile challenges and highlighting what can realistically be adapted. **What you’ll take away** * Uncover critical perception gaps, such as the ‘Culture Blind Spot’, that are holding teams back without leadership realizing it. * See the shared roadmap executives and teams actually agree on for scaling Agile beyond pilots and isolated successes * Identify the human factors currently undervalued, contributing to stalled innovation in the majority of organisations and talent loss eventually. * Learn how to move beyond the ‘delivery’ toward healthier, more resilient organizations This session is ideal for leaders, managers, Agile practitioners, and anyone interested in the future of work and organizational agility.

Tired of `git rebase` conflicts? Wish you could edit your commit history without fear? Join us for a hands-on introduction where we'll cover some \`jj\` basics and get to use it in action! \`jj\` is a modern version control system that's compatible with Git but designed from the ground up to be: simpler and easier, but also more powerful ! Pretty bold claim, right ? In this hands-on session, we'll explore: * What jj is and why developers are excited about it * Basic jj commands and how they compare to Git * Setting up and using jj with Git repositories * (yes, you can use it on your existing projects!) * (and, no, the rest of your team doesn't have to adopt it!!) * Core workflows: creating commits, viewing history, and making changes * A quick look at what makes jj different (automatic commits, simpler history editing) **What to bring:** * Your laptop (ideally with \`jj\` [installed](https://docs.jj-vcs.dev/latest/install-and-setup/) ) * Curiosity about alternative version control workflows **Who should attend:** Developers of all levels who use Git regularly and are curious about modern alternatives. Whether you're frustrated with Git's complexity or just interested in exploring new tools, this workshop will hopefully entice you to try out something new that will spice up your daily workflows! No prior jj experience required—just familiarity with basic version control concepts. **Sponsors** Our sponsors for this meetup are [Yodeck](https://www.yodeck.com/) \- who are not only kindly providing the venue\, free of charge\, but who will also treat us to some snacks / drinks for the networking session after the meetup\! Do stick around and say hi!
