This approach is classic Waterfall [such as CMMI]. BRUF [Big Requirements Up Front] is the antithesis of an Agile approach. At the start of the project, the ONLY thing that should be done is the creation of High Level (broad in scope) User Stories (Epic's). As the development processeds these are factored down to smaller user stories, and eventually into Tasks which are placed on the Product Backlog. At the start of a sprint a certain number (typically based on Story Points) is moved to the Iteraction Backlog. Agile is all about defering every decision until the point where delaying it one minute longer would cause Harm.
