Ease of use is heavily impacted by:
1. The depth of analysis that can be performed, particularly how well the system allows a user to navigate back and forth between summary level performance numbers and the root causes that are deeper down, even down to the transaction level
2. The accuracy of the system, and how much the user must venture beyond it (implying swivel-chair/spreadsheet data integration) to verify that the numbers are right
3. The degree of integration between operational, financial, and process data, and how tightly those elements are wed in the system’s underlying schema. Loose or non-existent integration of these elements will result in tedious spreadsheet jockeying, if such manual integration is even possible.
In turn, Ease of Use also affects broader organizational buy-in.
