This model describes a simple diffusion process, where Potential Customers of a product are influenced into buying the product by word of mouth from Customers (who already own the product). The first view shows the diffusion process. The second view will add a production capacity variable which will potentially limit the quantity of product sold at any one time. The third view will describe the sales revenue generated from sales of the product.
Some of the theory behind models of this type is discussed in Chapter 4 of the Modeling Guide.
