[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“A Practical Guide to Social Change,”** a research-based look at how communities bring about reform and progress, with Marissa Robinson, founder of Real Health Impact LLC and an adjunct professor at George Washington University who teaches courses focused on public health leadership and social change. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/dc-social-change](https://www.ticketleap.events/tickets/profsandpints/dc-social-change) .] Systems built on inequality rarely transform without deliberate pressure from the people most committed to justice, because progress takes coordination, conviction and willingness to change what has always been accepted. Real change starts when people choose to move together. Learn what research and experience say about how to make real social progress with Dr. Marissa Robinson, a public health practitioner who previously worked in federal agencies coordinating global and national public health initiatives focused on infectious diseases, HIV, and health equity. Among the key questions she’ll tackle: How do communities overcome barriers to create real change? When should evidence guide decisions and when does context matter more? She’ll discuss established frameworks for moving from intention to measurable progress and talk about the importance of building coalitions that actually work and of making decisions grounded in real data. You’ll learn about the importance of testing ideas on a small scale before going big, as well as how to use rapid feedback loops and continuous improvement cycles to refine approaches and scale what truly works. Dr. Robinson will share stories of ordinary people and communities who refused to accept the status quo and pushed through real barriers to achieve breakthrough results. She’ll talk about practical strategies, usable frameworks, and evidence-based examples that people can apply immediately in their own communities and organizations to support change that lasts. If you have dreamed about bringing about progress in your world, this talk will give you the clarity, direction, and confidence it takes to turn such dreams into reality.

**The Test Tribe 2nd Washington Meetup – Designing a Modern QA Organization: Structure, Skills, and Shared Ownership** AI is accelerating software delivery at an unprecedented pace-but speed without structure introduces serious risk. In today’s landscape, the traditional “testing bottleneck” isn’t just a delay-it’s a business liability. This session explores how Quality Engineering must evolve from a siloed function into a strategic, distributed capability-one that balances rapid AI adoption with strong human oversight. Moving beyond basic automation, this talk introduces the concept of Distributed Quality Governance, where quality becomes a shared responsibility across engineering, product, and leadership. Expect a practical, leadership-focused discussion that cuts through AI hype and addresses the real challenges of testing complex, AI-assisted systems-while ensuring accountability, trust, and long-term resilience. **Event Details** * **Date: 21st January 2026 (Wednesday)** * **Time: 6:00 PM – 8:00 PM EDT** * **Location: 1501 Langston Blvd. Arlington, Virginia** **Session: Designing a Modern QA Organization: Structure, Skills, and Shared Ownership** **Speaker: Alekhya Guduri** **About the Session** In an era where AI-generated code is accelerating delivery, quality can no longer be treated as a final checkpoint. Instead, it must be embedded, intentional, and governed. In this session, Alekhya Guduri presents a blueprint for building a modern QA organization that operates as a strategic business function. You’ll learn how to shift from centralized testing teams to shared ownership models, while introducing guardrails that ensure responsible AI use across the delivery pipeline. From defining a Materiality Matrix to identify where AI risks are too high to ignore, to implementing Human-in-the-Loop frameworks, this talk provides actionable guidance for leaders navigating AI-driven engineering environments. **Key Takeaways** * The Materiality Matrix: How to objectively prioritize AI risks based on business impact and technical complexity * Distributed Governance: Transitioning from centralized QA to shared ownership in AI-driven CI/CD pipelines * Responsible AI Guardrails: Practical Human-in-the-Loop frameworks to prevent bias, hallucinations, and silent failures **About the Speaker** Alekhya Guduri is a seasoned technology leader whose career sits at the intersection of engineering execution, operational excellence, and innovation. As Director of Engineering at Indeed, she focuses on building high-performing organizations that treat quality as a strategic advantage, not a last-mile activity. With deep experience scaling complex systems and leading cross-functional teams, Alekhya works at the forefront of shaping how AI and human judgment coexist within modern software delivery. She is a strong advocate for distributed governance, responsible AI practices, and the evolution of Quality Engineering into a trusted business partnership. **Why You Should Attend** * Learn how to design QA organizations for AI-driven delivery * Understand how to balance speed with responsibility in modern pipelines * Gain leadership frameworks for shared ownership of quality * Move beyond AI hype to practical, defensible testing strategies * Connect with Washington-area QA, engineering, and tech leaders **About The Test Tribe** **The Test Tribe** is the world’s largest software testing community, empowering testers globally since 2018.
