We are a global organization leading a global change. With affiliates, compliant software alliances and instructors throughout the world we are changing the way businesses plan, operate, think and evolve. The Demand Driven Institute (DDI) was founded in 2011 by Carol Ptak and Chad Smith. Collectively, Ms. Ptak and Mr. Smith have authored or co-authored several published works on Demand Driven Principles, Finance and Information and Planning Systems. Their book Demand Driven Material Requirements Planning is THE authoritative work on the emerging DDMRP method. DDI educational products are a powerful suite of enterprise education designed to enable companies to begin and sustain an implementation of a Demand Driven Operating Model (DDOM) and the Demand Driven Adaptive Enterprise (DDAE) model. DDI offers a comprehensive series of professional endorsement certificates. These endorsement certificates are the gold standard in ensuring and identifying an individual’s understanding, ability to apply, analyze, evaluate and create value using Demand Driven methods. DDI evaluates and certifies software ensuring that a specific software has enough features and/or functions to implement, sustain and even improve a DDMRP implementation. This objective evaluation and certification is provided free of charge to software entities. If you are considering a software claiming DDMRP functionality look for the DDI compliance label.
