Abstract: The invention provides a system and method for analyzing data from sales staff for multiple active business-to-business (B2B) sales opportunities—and generating a sales revenue forecast, along with additional valuable information to give the business management insight into future potential changes in revenue. The present invention lets a user define stages of selling progress based on steps known as Customer Decision Elements (CDEs) that deliver value to the customer's decision-making process, as input data, as well as the dollar value of the active sales opportunity. The sales progress in completing these defined stages is also entered into the system of the present invention.
