With a clear and complete functional specification, a knowledgeable resource can configure a Data Mart very quickly. This makes it worth the time to create a good implementation plan at the start. The following sections provide information on how to start to develop an implementation plan.
Inventory the Fields and Groupings to be Supported
The first step in planning a Data Mart is to take as complete an inventory as possible of all the fields and groupings you plan to support in your information delivery project. The more complete the inventory, the better you can create a logical and economical design of models, model extensions and groupings. This does not mean that use of the Mart is an all or nothing or big bang step, only that within the scope of the data to be supported in the Mart, a complete inventory of it makes for a better plan.
