Remember this famous line from the movie "Jerry Maguire" where the character of Cuba Gooding said, "show me the money!"
In collaboration and partnership, the true test where there is partnership and collaboration is the mandate/project.
Collaboration for collaboration's sake is nonsense.
There is no collaboration or promise of collaboration where there is no single uniting focus of where the collaboration will be.
Promises are never guaranteed, unless we are talking of real, tangible benefits and rewards and the "work" that needed to get done by all the collaborators.
It is not just 'tit for tat'- it is more than that. It is about collaborating on a specific mandate that is too good to leave on the table and yet to powerful to be done by one organization or entity alone.
Show me the money (or in some instances -the mandate) and I will show you how we can partner together.
