Two complementary takes on what actually decides whether AI delivers value in an organization. One on why role-based structures are the real enabler, the other on what happens to teams when AI starts resolving the tickets. Here's what's planned for the evening: 17:30 - 18:00 - Arrival and first drinks 18:00 - 18:45 - AI Value Creation Starts Beyond Technology by Ralf Günthner 18:45 - 19:30 - When the Bot Takes the Ticket: Keeping Teams Effective as AI Rewrites the Rules by Dagmar Muth 19:30 - 20:30 - Networking, Open Space & More drinks\* **AI Value Creation Starts Beyond Technology** Many companies are currently investing heavily in AI agents, copilots, and automation, yet the expected gains in productivity and innovation often fail to materialize. The reason is rarely technological, but structural: classic hierarchical organizational models are not designed to collaborate effectively with learning, adaptive systems. This keynote explains why role-based work is the decisive enabler for successful AI adoption. In role-based organizations, responsibilities are clearly defined, decision rights are decentralized, and collaboration is dynamically organized, exactly the conditions under which AI agents can deliver maximum value. Drawing on current research (including McKinsey, MIT CISR, and Harvard Business School) and practical examples from industry, mechanical engineering, and chemicals, the keynote shows how companies can combine AI agents with role-based structures to: * drastically shorten implementation timelines * increase acceptance and trust in AI * enable continuous optimization instead of one-off pilot projects * significantly improve the ROI of AI investments The core message: AI does not transform organizations, organizations determine whether AI creates impact. Those who invest today in role-based ways of working, shared leadership, and decentralized decision logic build the operational foundation to not only introduce AI, but scale it strategically. **Ralf Günthner** Ralf Günthner is a transformation expert, entrepreneur, and lecturer with over 25 years of experience in digital transformation, AI, IoT, and organizational development. In his keynotes, he shows why AI value creation does not emerge from algorithms, platforms, or tools, but from leadership, culture, decision-making logic, and effective collaboration. He combines deep technology expertise with systems thinking, neuroscience, and hands-on transformation work. As Co-CEO of Team-Factory GmbH, he supports companies in anchoring AI strategically, creating orientation, and delivering sustainable impact, beyond hype and technology fixation. **When the Bot Takes the Ticket: Keeping Teams Effective as AI Rewrites the Rules** AI agents are starting to resolve incidents, write code, and close tickets. That's great for throughput, but what happens to the humans in the team? Motivation, ownership, skill development, and psychological safety don't disappear as team development topics just because productivity metrics go up. In this talk, Dagmar Muth draws on her work with engineering and product teams navigating AI-driven transformation. She shares what it takes to make AI integration work for the whole team: how to preserve ownership and purpose, keep accountability clear, and build the patterns that distinguish teams that thrive from those that merely adapt. You'll leave with a clear mental model for thinking about team health in AI-augmented setups and concrete questions to bring back to your own team or organization. **Dagmar Muth** Dagmar Muth is a systemic organizational developer and agile coach with 20 years of experience guiding teams and companies through transformation. As a co-worker of pragmatic solutions ag in Zürich, she supports organizations in finding the right setup, processes, and culture to sustain performance from vision to go-live, increasingly in contexts shaped by AI. She works with cross-functional tech and product teams, coaches leaders, and lectures on agile project management at SIB. Her particular focus right now: how organizations integrate AI without losing what makes their teams actually work.

Welcome to the **Task-Buddies** event of the **Zürich Productivity Circle**, where we bring together like-minded individuals to work on personal goals and share the experience of growth in a supportive community. Maybe you are building a business or side hustle, studying for a course, learning a new (programming) language, figuring the tax system out, writing code, prose, or poetry, researching new stocks for your portfolio, tackling your German homework, or upskilling for your job. In all of these cases and more, this is the perfect space for you. In fact, productivity does not end there. Even if you just want to read a psychology book to resolve a personal struggle, sketch a mountain, listen to podcasts, organize your week, respond to unanswered emails and messages, enjoy a novel, or just reflect and meditate, you are very welcome here. For any task that adds positively to your life and can be done sitting down with others (exception: anything noisy/disruptive/disrespectful), you will fit into the events. We will meet at a work-friendly café in Zürich and follow the agenda below. **Agenda:** * **Introductions and food (20-30 mins):** Start with a round of introductions to get to know each other and share what we'll be working on, buy our food and drinks (alternatively one can also buy them later on). * **Productive Work Session (1-2 hours)** Dive into your individual tasks in a focussed, distraction-free environment. * **Collective Break and Socializing (\~15 mins):** Take a planned break to stretch, chat, get more coffee, and share insights about your projects. * **Continued Work Session (1-2 hours):** Get back to your tasks with renewed focus and motivation. * **Wrap-Up and Reflections (15+ mins):** Conclude with a reflection on what we accomplished, share productivity tips or questions, discuss plans for future meetups, stay back for more chit chat if you like. **What to Bring:** * Your project or task materials (laptop, charger, books, sketchpad, pen, etc.) * Respectful and kind demeanour * A positive attitude and a willingness to share and learn **Note:** Please ensure that your tasks are suitable for a quiet, communal setting.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics & Scientology life improvement center.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
