The Forrester Growth Engine Planning Tool captures the key processes and parameters of aligned sales and marketing planning. The tool supports a structured approach to quantifying when and how many inquiries must be generated to achieve a defined marketing contribution to revenue, and the resources necessary to support the qualification of the resulting leads. With this tool, planners can easily conduct the calculations required for a best-in-class revenue engine planning process. The tool establishes a framework for modeling the demand engine and performs the calculations so that planners can focus on modeling the inputs to maximize results.
