Very good commentary around why PivotLink chose Boomi as a data connector vendor. I agree with your reasoning and approach. In this day and age, organizations must focus on their core competency and try to leverage partner network where ever possible to maximize organizational, customer and partner value.

There are so many examples in other areas of industries where industries/businesses know where to draw a line and where to engage partners. For example, take airline industry…. most of the major airline carriers are in transportation business. But Airline industry does not provide transportation services from door to door to its passengers. They rely on local mode of transportation (Taxis, Limos etc…) or even rely on customers to drive in to the airport. Airlines specialize in flying people from one airport to another that is their core competency (to fly people from one location to another in a economically effective manner with highest possible safety and accuracy). Another example is your physician. Physicians will take care of your general health and involve subject matter experts for their competencies. When you want to do cholesterol or sugar testing, doctor will recommend you to lab and will rely on lab to do the blood work. Ultimately Physician will interpret the results and decide the course of action (which is their core competency).
Good luck with the partnership and hope things work out for both of you.
