I very recently had the opportunity to work with a large telecommunications company as they embarked on an enterprise data modeling effort. Building an Enterprise Data Model (EDM) of an entire corporation is no small feat and there can be a large initial investment in time and money followed by a maintenance effort for the life of the EDM.
Here’s the challenge. You are the manager of this newly formed enterprise modeling group and you need to “sell” the EDM to senior management. You plan on explaining the benefits of increased business understanding across departments, higher quality data, and lower software development costs over the long term. But…you know they will ask you what the Return On Investment (ROI) will be for the EDM. How would you answer the question, “What is the EDM ROI?”
