How to make other employees involved in boosting user engagement?

How did you gain support within your organization to ensure everyone recognizes the value of community and actively helps boost engagement? How did you shift the mindset so that community engagement isn’t seen solely as the community manager’s responsibility?

I think, in the situation when behind a community there is a whole company, the community manager acts as a bridge representing the company in the community and the community inside the company. It means that the CM should use more or less the same techniques within the company as they do within the community. In the case that you described, I think I would do two things. First of all, I would work on my relationships with co-workers. I would also try to understand what they are interested in and what their strongest skills are. Then, when I would look for the opportunities where my colleagues can show off their skills in the community. As a chance arises, I would kindly ask them for help, pointing to the opportunities available.
