When there is an opportunity for a person who owns a system created by components from two different vendors to be more streamlined, those vendors don’t often propose that value because while it represents possibly doubling the business, it could also mean losing what business you have if they standardize to the other vendors components.
This is a double-edge sword and it should only be wielded when there is an elevated chance of a favorable outcome. However, it’s also an opportunity. The other vendor feels the same way, so when something comes along such as a feature that breaks the possible stalemate, it may be time to test the waters. If you can focus on the feature that would be the tipping point, then you can wield that double-edged sword with more safety.
