Raise the floor: lessons from high-performance teams
Medals, titles, and records look like success – but they do not make you a champion.
In this ESMT Insight Hour, **[Tina Manker](https://www.linkedin.com/in/tinamanker/)**, Olympian, world champion, and coach for high-performance teams, invites participants to rethink what performance and leadership really mean. True champions are not defined by what they win, but by how they behave, especially when no one is watching.
Drawing on her experience in elite sport and her work with leadership and startup teams, Manker will explore how high performance is built collectively, sustained over time, and tested under pressure.
* What does it actually mean to be a champion when no one is watching?
* Which conversations are teams most likely to avoid, and why?
* Do you really want feedback?
* Performing on your best day is easy. But how do you perform on your worst?
* What difficulties await you when you leave your comfort zone?
Participants will leave with new perspectives on behavior, pressure, and responsibility, as well as practical insights into how teams can “raise the floor” to perform – and achieve – consistently.
The session concludes with an experiential element that brings the realities of preparation, pressure, and performance vividly to life.
Moderated by **[Hilde Rosenboom](https://www.linkedin.com/in/hilde-rosenboom-9bb7a2140/)**, Program Director, Executive Programs, ESMT Berlin

LSLab Berlin 10.2 @DeutscheBahn
**\*\*\* SIGN-UP on LUMA ONLY to get the address and attend!\*\*\***
**A Small Update for 2026**
Thanks to those who took the LSLab survey. We learned a lot, and will use that feedback to continue creating a dynamic, safe and relevant learning community. Starting now, there will be a few small changes, beginning with this meet-up, so we can test as we go.
So after many years on Meetup, LSLab Berlin is evolving.
**From now on:**
* Events will be announced inside Meetup, but *organized on LUMA* (**Link to sign up here:** [https://luma.com/vs42c5uc](https://luma.com/vs42c5uc)).
* We’ll charge a small participation \*fee when you sign up.
* Sign-ups to the email so updates can come from LUMA - no spam, just updates on LS events (address or date change, opportunities to be on the design team, events relevant for LS!)
This helps:
* Cover admin and multiple platform costs
* Support behind-the-scenes coordination
* Encourage attendance commitment
* Give our hosts a more accurate guest count
It’s about sustainability and respecting everyone’s time. We will see how it all works and make adjustments as we go.
\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*
**Here we come, Deutsche Bahn** 🚆
We’re on fire in 2026, our second Lab this year and we’re not even out of Q1. As always, we are looking to make it: fun, practical, slightly surprising.
**Theme:**
TBD – our design team meets next week and we’ll post the theme and string as soon as it’s ready.
**Our Host:**
We’re excited to be hosted by Deutsche Bahn. Their space gives us plenty of room to move, work in small groups, and play.
**What Happens at an LSLab?**
Every Lab includes:
✔️ Networking & connecting
✔️ Giving and Getting Help
✔️ A thoughtfully designed Liberating Structures “string.”
✔️ Action planning
We don’t do long debriefs during the session, on purpose. LSLab is a practice space, mostly for the Design Team, and the participant, you, learn by doing! By participating. By seeing what it’s like to be part of the collective intelligence.
Questions are welcome during the break and after we close.
**New to Liberating Structures?**
Totally fine. You don’t need experience. We’re a mix of beginners, experienced facilitators, agilists, OD/L&D folks, coaches, leaders, and curious humans who want better collaboration.
You’ll learn by being part of it.
**Language**
Intro and instructions are in English. Small group work can happen in whatever language works for you.
Mark your calendar. Come practice. Bring your curiosity.
See you there,
Sylvia
\*If you are facing financial hardship or have been laid off, we'll waive your fee. Just reach out to us and let us know. We want you to be able to contribute and connect with us!

Quality Engineering meetup #11
**PLEASE NOTE THE ADDRESS CHANGE! We're now at [w3hub.berlin](https://w3hub.berlin)**
*[Qase](https://qase.io) is presenting the **eleventh** Meetup on Quality Engineering in Berlin.*
*This time, we’re bringing you three deep-dive talks — all designed to challenge the way you think about quality, testing, and collaboration.*
*As always, expect great conversations, snacks, and drinks. See you there!*
**AGENDA**
**1\. Mitesh Patel\, Technical Consultant \- Scientific Instruments @ Altum Solutions: *Food QA: Testing Tasting***
On this fine evening, we shall enjoy some food … and also learn why we enjoy it. Because tasting is really a form of testing for our brains — wetware QA in essence.
But how do we reformulate this wetware testing into those familiar realms of software and hardware testing? It is not as simple as exchanging taste buds for test suites and bites for bytes. Just ask Big Food which spends billions on this same question: How can computers do taste tests like humans?
Guided by the example of an ML/AI-powered scientific instrument for chemical analyses, namely, a spectrometer, this session addresses this question and explores the broader topic of QA in the food industry. Discover how food companies scale testing across scientific software, device hardware, and food/human wetware. So grab a spoon for this insider scoop on QA for food.
**2\. Vitaly Sharovatov\, developer advocate @ Qase: *QA Myths Busting: A Practical Guide to Higher Quality***
Have you ever felt the urge to increase the amount of testing or hire more testers, thinking it would improve product quality? As a tester, have you ever been held “accountable” for quality or pressed for time, leaving you feeling helpless? Or perhaps you’ve been asked to justify quality assurance initiatives with numbers?
Our industry is filled with myths: from “quality can be measured” to “more testing means higher quality” and from “QA slows down work” to “testers are responsible for quality”. In this talk, I will present the myths I once believed, explain the dangers they pose to both teams and products, and demonstrate how they should be debunked and overcome.
**3\. Asya Isakova\, Co\-Founder @ TECH_Connect: 𝘌𝘢𝘳𝘯 𝘛𝘳𝘶𝘴𝘵\, 𝘒𝘦𝘦𝘱 𝘠𝘰𝘶𝘳 𝘑𝘰𝘣**
The job market is wild: it’s hard to get hired, and sometimes even harder to stay hired. In a new role (or a new team), one of the fastest ways to reduce uncertainty and accelerate collaboration is to build trust quickly.
But how do colleagues and managers decide you’re trustworthy? It’s rarely just about closing Jira tickets or moving cards on a Kanban board. People assess trust through patterns of behavior: what you do, how consistently you do it, and how do you act towards others.
In this talk, you’ll learn an evidence-based approach to building trust at work using three practical components: integrity, reliability, and benevolence. We’ll unpack what shapes people’s trust judgments (including context, risk, and prior experiences) and translate research into concrete behaviors you can apply immediately: especially in multicultural and cross-functional teams.

**Abstracts**
**How we made WarehousePG Open Source (again)**
WarehousePG is an Open Source fork of Greenplum Database, which by itself is a fork of PostgreSQL. The project was born after the upstream project was made closed source.
This talk gives a quick overview of the history of both projects, which already spans more than two decades. We then dive into the reasons for creating a fork, and all the stumbling stones we had to pass in order to make this project open source again. We also talk about the challenges of CLAs (Contributor License Agreements) and what implications the PostgreSQL and Apache Licenses have for the project.
Speaker: Andreas 'ads' Scherbaum
**The Role of PostgreSQL in the AI World**
As artificial intelligence (AI) continues to revolutionize industries, the need for robust, scalable, and efficient data management solutions has never been greater. PostgreSQL, with its extensibility, performance, and advanced data capabilities, plays a crucial role in enabling AI-driven applications. This talk explores how PostgreSQL supports AI workloads, from managing vast datasets and integrating with machine learning frameworks to leveraging extensions like PostgreSQL ML, TimescaleDB, and JSONB for AI-ready storage and querying. Attendees will gain insights into best practices for using PostgreSQL in AI pipelines, optimizing performance for AI inference, and harnessing the power of open-source innovation to drive intelligent decision-making. Whether you're a data engineer, AI researcher, or PostgreSQL enthusiast, this session will showcase why PostgreSQL is an essential component in the AI ecosystem.
**From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups**
CloudNativePG (CNPG) is a popular and battle-tested operator for running Postgres on top of Kubernetes. At Xata, we’ve been using CNPG and extending it in several different directions. One of them is implementing a scale-to-zero plugin: clusters hibernate when inactive and they wake up automatically when new connections are created.
After adding scale-to-zero, we’ve faced the challenge that the CNPG wake-up from hibernation is rather slow.This is an optimization story about how we reduced the wake-up times from 20+ seconds to under one second.
Speaker: Tudor Golubenco
**Modernizing Postgres Communication with Hackorum**
In 2026, the debate over whether mailing lists are still "state of the art" continues to divide developers. While some view them as relics, we cannot neglect the unique benefits of their decentralized, archival nature. Rather than fighting over platforms or ignoring the friction, Hackorum asks a simpler question: Why not just improve the user experience?
Hackorum transforms the daunting mailing list "firehose" into a modern, forum-style interface without breaking the underlying email culture. It is designed to lower the barrier for new contributors while providing power tools for veterans:
Seamless Integration: Real-time sync between mailing lists and daily sync of the Commitfest status.
Modern UX: Per-message read tracking, tagging, and contributor profiles.
Enhanced Coordination: Shared notes and mentions to streamline complex reviews.
We have to stay open minded and willing to expand our horizon and as such Hackorum is rapidly evolving. While our roots are in development, we are currently expanding to include broader mailing lists like -general and -docs. Our goal is to make the entire Postgres ecosystem more accessible and usable for everyone. Join us for a demo of the latest updates and help us shape the future of Postgres communication.
Speaker: Kai Wagner

Data & Analytics Wednesday - Google Analytics Alternatives
**Google Analytics Alternatives**
Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday.
Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”.
Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process.
We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
