The material gathered here is a glimpse into the process of forming these collaborations.
Communication is a constant challenge.
Expect to disagree. Develop a healthy mechanism for ironing out differences, or you will be getting together only when things go wrong. It won't last if it's just built from the top. It's important to recognize and acknowledge early on the strengths of the medium of each partner. To the extent the partners have flexibility, assign maintenance of the partnership to staffers who enjoy building consensus.
