This webinar presents an update on developments in the Guild Manufacturing Reference Model and Companion Guide. In 2024, the team's major activities involved drafting and revising six business architecture scenarios, relating to the Manufacture Product, Acquire Material, Develop Product, Delivery Initiative, Deploy Asset, and Acquire Product value streams. 2025 thus far has seen development of expanded value stream-capability cross maps, proposal and review of model modifications, and enhanced planning and administration aids. Manufacturing Reference Model 5.0.1 is anticipated, bringing the model into conformity with the revised Common Reference Model and adding new manufacturing-specific enhancements. For those interested in leveraging business architecture to drive manufacturing efficiency and innovation, please join us for this informative session. Time will be allotted at the end of the session for questions, comments, and suggestions.
