I am part of a new team and have been working on an innovative project which brings great benefits to customers and has a big revenue pipeline behind it. The project we worked on aligns requirements from customers of all teams and delivers a solution which is efficient, long-term and in demand.
We have executive sponsorship, but execs want me to align with other teams in the organisation, from other regions.
With some teams things are working fine.
Some teams are lukewarm - they are happy to discuss, but not too happy.
Some of these teams are deliberately ignoring my project, even when their customers would like to hear more.
Another team has been recreating our work "in their own words" and putting their name on it.
These teams will not push projects which are not theirs, and don't seem to be happy that there is a solution out there to help their customers. I know that some key stakeholders would be happy to see our big project shut down, so that their own local initiatives can advance.
I was asked to create a "WIN-WIN" situation: indeed, our project will help their customers and help their revenue numbers. Even then, they want our project dead and buried.
How do I get buy-in for a project which goes beyond what my colleagues were working on?
