Services incorporate the four I's of product marketing. How would each of these four elements apply to a stock brokerage service?

The four unique elements of services are: (1) intangibility-a brokerage service is intangible because it cannot be seen, held, or touched before the purchase decision; (2) inconsistency-the quality of a brokerage service will vary because different people, who vary in their job performance, provide this service; (3) inseparability-consumers cannot separate the service (stock purchase) from the deliverer of the service (stockbroker) or the setting in which the service occurs; and (4) inventory-brokerage services have little inventory carrying costs because the brokers work on commission. If a broker does not make any sales, commission costs will be lower.
