Question

What is the difference between a map with base case, high case, and low case top structure?

i.e. what is the difference between the different "case" terminologies?

Answer 1

Base case:

Financial model, or financial projections. The expected case of the model using the assumptions that management deems most likely to occur. The financial results for your base case should be better than those for your conservative case but worse than those for your aggressive, or upside case.

high case and low case:

In cost accounting, the high-low method is a way of attempting to separate out fixed and variable costs given a limited amount of data. The high-low method involves taking the highest level of activity and the lowest level of activity and comparing the total costs at each level.
