The document provides an overview of considerations for organizations that have migrated to Office 365 but are still operating with a "classic" approach. It discusses adopting a "modern workplace" mindset that is intent-driven rather than technology-driven. Key changes include moving from a product-focused to intent-focused governance, rethinking the site architecture to be flat rather than hierarchical using Office 365 groups, and enabling self-service options like Microsoft Teams while establishing appropriate policies. The document recommends organizations modernize their planning and provisioning processes, implement cross-product governance policies, and evaluate how IT is delivered by focusing on customer needs and adopting a "product team" approach.
