Ausschreibungen sind ein zentraler und oft unterschätzter Bestandteil professioneller Requirements-Arbeit. Ausschreibungen verbinden fachliche Anforderungen, rechtliche Rahmenbedingungen und wirtschaftliche Interessen. Und entscheiden nicht selten über den Erfolg ganzer Projekte. In diesem Meetup beleuchten wir Ausschreibungen aus **drei komplementären Perspektiven**: 👉 aus Sicht des Auftraggebers, 👉 des Bieters und 👉 des Software-Herstellers, der beide Welten zusammenbringen will. 🔹 **Speaker 1** – Simon Gemel (Business Analyst) gibt Einblicke aus erster Hand in die Erstellung und Begleitung einer Ausschreibung für das Parlament: Wie entstehen Anforderungen in diesem Kontext? Welche Herausforderungen gibt es auf Auftraggeberseite und was macht eine gute Ausschreibung wirklich aus? 🔹 **Speaker 2** – Armin Fürst ([TechTalk](https://techtalk.at/)) bringt die Perspektive eines Unternehmens ein, das regelmäßig an Ausschreibungen mit dem klaren Ziel teilnimmt, diese zu gewinnen: Worauf achten Bieter? Wo gehen Anforderungen oft verloren? Und wie unterscheiden sich „formal korrekt“ und „inhaltlich überzeugend“? 🔹 **Speaker 3** – Gerhard Hipfinger ([openFORCE](https://openforce.com/)) stellt eine Software-Lösung vor, die genau an dieser Schnittstelle ansetzt: Wie kann intelligentes Matchmaking zwischen Anforderungen und Angeboten Auftraggeber und Anbieter gleichermaßen unterstützen und Reibungsverluste reduzieren? 👉 Das Meetup richtet sich an **Business Analysten, Requirements Engineers, Product Owner, Architekten, Auftraggeber, Juristen und alle**, die Anforderungen formulieren, bewerten oder in Ausschreibungen damit arbeiten. Freut euch auf **Praxisberichte, unterschiedliche Blickwinkel und konkrete Learnings** und für Diskussion und Austausch mit der BA-Community. 🕑 **Agenda** 👉 Einlass ab 17:30 👉 Start der Vorträge um 18:00 🙌 **Über unseren Sponsor…** Der Veranstaltungsort wird von **[TechTalk](https://techtalk.at/)** gesponsert. Essen & Getränke gesponsert vom **[IIBA Austria Chapter](https://austria.iiba.org/).** 🍻 **🎤 Call for Speakers & Sponsoren!** Und wenn du selbst etwas erzählen willst oder eine Idee für einen Talk hast, dann melde dich einfach. Auch suchen wir nicht nur Sprecher, sondern neue Lokationen zum Vortragen. 👉 **RSVP now!** Die Plätze sind begrenzt, also melde dich bitte an. Wie immer freuen wir uns sehr auf dich! Wir freuen uns auf eine rege Diskussion!

Liebe Freunde! Wir laden euch zu einer Premiere in Österreich ein und würden uns über eure Teilnahme sehr freuen! LESUNG MIT ÇETIN GÜLTEKIN & MUTLU KOÇAK "GEBOREN, AUFGEWACHSEN UND ERMORDET IN DEUTSCHLAND" Am Donnerstag , 12.02.2026 - 18.00 Uhr in Wien (am 13.02. in Graz, 14.02. in Salzburg, 15.02. in Linz) veranstalten wir, Projektgruppe der BHAK BHAS Wien 13 eine Gedenkveranstaltung an den Hanauer Anschlag vor 6 Jahren! Am 19. Februar 2020 ermordete ein Attentäter in Hanau (D) neun Menschen aus rassistischen Motiven. Gökhan Gültekin war einer von ihnen – einer von denjenigen, die der rassistische Täter nicht in „seinem“ Land ertragen konnte. Seither setzt sich sein Bruder Çetin Gültekin dafür ein, dass die Opfer und deren Geschichten nie vergessen werden – und kämpft unermüdlich gegen den tief verwurzelten Rassismus in Deutschland. Alle Infos zur Veranstaltung und Tickets unter: 📲 0680 551 69 78 📝 Event@bhakwien13.at Vielen Dank für euer Interesse! Projektgruppe der RISL 4AKJK BHAK Wien 13 Projektbegleitung Dipl.-Theol.

Join us for a nurturing and empowering in-person afternoon at **commonroom** for a form of networking going deeper. A local expression of our global **[Women Lead Community](https://women-lead-community.mn.co/),** each month we create a space for women to slow down, connect with themselves and others, and explore a new form of leadership grounded in **presence, purpose, and mutual support**. After a joint arrival, we take the time to reflect on our needs as well as what we each have to offer to the world. We have the opportunity to practice pitching our offers and needs in a safe space and connecting with other inspiring women who are eager to support each others growth. Just come as you are – curious, present, and open. No need to prepare anything. Bring a friend or meet new ones. Have something to write with you for the reflection and bring business cards and flyers of your offers, if you have any. The sessions are held in **English**. They are open to women of all backgrounds who are curious about co-creating a more conscious, caring, and connected world. If you are not yet part of the [Women Lead Community](https://women-lead-community.mn.co/) it would be amazing if you could sign up to our free community platform before the session. We encourage you to include your offers and needs in our virtual marketplace at the end of the session to reach even more women who could support you.

**Note:** We are meeting outside again as the first one was very successful. There is also a picnic in the nearby location so we may try to learn languages while having fun and learning sports vocabulary. Bring a blanket to sit on and water and snacks if you like. This is a **free** event. Are you ready to practise your language skills? If you want to meet new friends (or the same friends you met at our other events) and practice all the languages you can speak, join us for a fun-filled evening! During this event, you have the chance to choose a Group and talk to people in: 1. **English** 2. **German** 3. **Italian** 4. **Spanish** 5. **French** Our most important rule: Please be respectful to others at all times. Yes, there will be a separate beginners' Group if you aren't fluent in the language yet! It is also a great place to find Tandem Partners for the languages you want to improve in! Get in touch with the Host upon your arrival and he/she will assist you. 🟢📱 here is our WhatsApp link https://chat.whatsapp.com/KtZ1TQB7lnUAJXK5NxwPQU Hope to see you there!!!

Hi Running fellows, Whether you’re a walker, new to running, a semi-pro, a marathonist or a sprint star - if you want to start your weekend in an active way and enjoy the outdoors in lovely surroundings with a fun, international and multilingual group of people, you are welcome to join us! Every Saturday at 9:30 am, we meet, we run, in the magnificent Schönbrunn park, and then we go for breakfast. Want to discuss politics or the best recipes for banana pancakes? Not a problem. Not feeling social? Tune out with your earbuds - we can talk over breakfast. We are casual. You can be too. What to expect: Start by meeting Adrian, Ali, Liz, Paul and Sonia on-time at 9:30am outside the Schönbrunn U-Bahn stop (exit Grünbergstraße). (Coordinates: 48.1858130, 16.3200640) From there, we walk to the side park entrance where the “running” part begins. The important thing is that you run at your own pace. Typically, small groups of people will run at the same pace as you, so you never have to walk/run alone :) We finish one hour later, at about 10:40am, reconvening just inside the Hietzinger Tor exit. (Coordinates: 48.1858825, 16.3032647). From there, we’re off to breakfast! Breakfast Details: Anker bakery opposite the U4 Hietzing station and depending on the weather, grab something for a picnic in Schönbrunn park, or hang out in the bakery. If you missed us earlier, you can always go there around 10:45. We are a fun group of runners who don’t take things too seriously. We meet, chat, RUN, stretch, chat, EAT and we hang out over a beer every now and then. It's that easy. Please join us for breakfast after the run! The more the merrier. Typically we are 10-30 people, as not everyone who comes signs up on meetup. Important disclaimer: Please only run as much as you feel you can, considering the temperature, weather conditions, your own fitness etc... run and walk at your own pace as the organizers do not assume any liability for any injuries or health issues. Sonia, Adrian, Ali, Paul and Liz

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

Join us at **Unity of Columbus** for *Spa for Your Soul*, a restorative and inspiring workshop designed to nourish your spirit, awaken your inner wisdom, and reconnect you with the sacred rhythm of life. Drawing from the rich spiritual insights of **Matthew Fox** and the timeless theological wisdom of **Thomas Aquinas**, this workshop invites participants into a deeper experience of spirituality rooted in compassion, creativity, and divine presence. Together, we will explore spirituality not as something distant or abstract, but as a lived, embodied experience—one that honors joy, justice, beauty, and the inherent goodness of creation. Through guided reflection, gentle spiritual practices, discussion, and contemplative moments, *Spa for Your Soul* offers a sacred space to release stress, renew clarity, and remember the divine spark within. This is an opportunity to pause, breathe, and tend lovingly to your soul—much like a spa experience, but for your inner life. Whether you are seeking spiritual refreshment, deeper understanding, or simply a peaceful space to be present, this workshop welcomes you exactly as you are. **Come, rest, reflect, and renew—your soul deserves it.**
