How to select an analog product/technology?

In most applications of the Bass model, the selection of analog products will be the critical decision in the successful implementation of the model.

Although similarities of product/technology features between the focal product and the analog are one aspect to consider in selecting suitable analogs (particularly the price points of the two products), the primary consideration should be similarities between the focal product and the analog(s) with respect to expected customer behaviors.

Here is a list of criteria developed in the seminal work of Rogers (1962) that is useful to keep in mind:
(1) ease with which the customer can try the product/technology before purchase,
(2) relative advantage of the product over existing alternatives,
(3) compatibility of technology with existing practices,
(4) Ease of use of the technology, and
(5) Observability of the “benefits in use” of the technology.
