Spending hours re-explaining or revising data models when stakeholders push back
The situation this course is for
Even certified MDM professionals face challenges when peers demand justification for entity resolution rules, hierarchy designs, or source system authority. Without concrete reasoning, decisions get delayed or overturned.
Who this is for
A data governance professional who has formal MDM training and now needs to assert judgment in high-stakes, cross-functional settings
Who this is not for
Those seeking introductory MDM concepts or platform-specific configuration guides
What you walk away with
- Articulate the why behind any master data decision using documented precedents
- Reference industry patterns and implementation trade-offs under pressure
- Reduce rework caused by stakeholder skepticism or late-stage challenges
