But you've got to do the math. Most of the time it boils down to answering just two questions:
Let's leave out sales cycle length for now, to keep things simple. Let's just look at leads-to-opportunities-to-sales.
To build the model, you need a handful of inputs:
If you don't know these figures explicitly, come up with a reasonable but somewhat conservative guess. With this input, you can build a model telling you:
And with that model, if the inputs are isolated and the lead/opportunity/sales figures are calculated with simple formulas, you can make adjustments to the inputs to see what the sales and/or revenue impact would be if you:
