Would you build a house without a blueprint? Why would you build a model without one?
As a first step in building a new model, a map was prepared to illustrate the flow of the inputs and outputs and to visualize and identify interdependencies critical to determining the structure of the model.
The blueprint was key to aligning stakeholders and driving mutual understanding of the model drivers and the resulting reporting. It also served as an essential reference document in the FP&A process.
