"dev guy" differs from a "Salesman"
in that he does not have a quota, is not bound by selling
from a defined list of offers, and is expected to initiate
efforts to create new offers, secure revenue based partnerships
and new business.
His time horizon is generally 3-5 quarters or 2-4 times
the sales cycle.
(please pardon our use of the male pronoun,
it is regrettably accepted.)
