A method for operating a computer to enhance profitability of a portfolio
using a profitability model includes prompting a user to enter at least
one workload driver for the portfolio, prompting a user to enter a
trigger level for each entered workload driver and allocating portfolio
and underwriting expenses, based upon workload drivers and their trigger
levels. In an exemplary embodiment the method is implemented using a
server and a database to evaluate deal economics within portfolios based
on workload requirements relative to market pricing levels. Workload
drivers and trigger levels cause the model to be activity based rather
than average cost based.
