I want to ask an FDD question regarding the feature list for the DM layer. We derived feature lists for the PD, UI, SI and DM layers, however our main FDD person is now telling me that we should scrap the DM list as DM features are never client valued. He says that such development work should be amortised within the PD feature list.
The only documentation that I have found on the topic is the following thread:
In it Jeff discusses the 4 layers but dismissed the DM layer as a layer that you never build anymore, but rather buy a solution. For a green fields project I entirely agree. However as our project has already been built using home grown data management, and considering our current release is not big enough to justify a full replacement of the DM layer, we are stuck supporting the layer. In this case should we or shouldn't we derive a DM feature list?
