As consultants, we all chase the same dream: a perfect, repeatable, "Golden Configuration" that we can deploy to any client with the push of a button. With Microsoft’s new Unified Tenant Configuration Management (UTCM) APIs, that dream is finally becoming code. Join Dennis and me as we open the hood on the new UTCM capabilities. We won't just read the documentation; we will show you how we built a scalable "Purview Fast Track" engine for our own clients. In this session, we will cover: The Signal vs. The Noise: How to extract tenant data and identify which settings are actually useful for your templates. The Blueprint: A step-by-step guide to building a "Golden" configuration template. The Deployment: Practical strategies for pushing these configs to new (and existing) clients. Real-World Application: Exactly how we automated our Purview deployments to slash onboarding time. Stop clicking through portals and start deploying standard excellence.

Getting Copilot is the easy part. The real challenge is shifting company culture from "How does this AI thing work?" to "How can we work better using AI?" We believe you don't need to be a developer to master AI—you just need the right adoption framework. Because you need to understand it first, before you can decide if it fits you(r work), and then implement it. Join us as we share our field-tested strategies for onboarding entire organizations to the AI era. We will move beyond generic training and show you practical, human-centric implementations that actually drive engagement. We will share our recipe for: The "AI Cafe": Creating safe, social spaces for users to experiment and fail forward. "Wake Up Calls": Proactive engagement techniques that turn skeptics into power users. Business case driven: How we use Copilot Studio to build knowledge groups and measure feedback in real-time. The Scorecard: Metrics that matter—going beyond "daily active users" to measure actual efficiency gains.

As an M365 Admin or Developer, you now have two powerful options to manage tenant configuration, deploy a "golden" template or monitor configuration drift: the battle-tested Microsoft 365 DSC framework and the new Unified Tenant Configuration Management (UTCM) APIs. The question is: Which one should you use? Dennis and I are here to clear the fog. We will break down the similarities and critical differences between these tools. We will show you real-world code examples of how to define a "Golden State" using both methods, highlighting the pros and cons of each workflow. Key Takeaways: Compare & Contrast: A feature-by-feature breakdown of DSC vs. UTCM. Code Demo: See the difference between writing a DSC Resource and a UTCM JSON template. Decision Framework: A checklist to help you decide which tool fits your specific project or client. Because as always... "It depends"

Deploying Microsoft Purview isn't just a technical task; it’s an organizational change. Too often, consultants only deploy a "Golden Config" and leave, only for the organization to struggle with over-blocking and user frustration. Join us as we break down our proven "Purview Fasttrack" methodology. We will show you how we combine a standardized technical baseline (covering the critical 60-80%) with a robust adoption program to ensure a "soft landing" for the business. We will open our playbook on: The 8-Week Timeline: How we structure the journey from education to requirements, roadmap, and deployment. The "Soft Landing" Strategy: Why we target 60-80% coverage first and iterate "special" data. Copilot Readiness: How this approach specifically prepares your data estate for the safe introduction of AI. Stakeholder Education: How we teach the "Why" and "How" to IT, users, and leaders so they become champions, not blockers.
