We started a 4-day training program with a 2-day session in a forest retreat including dining and an overnight stay to foster team building and informal cross-departmental relationships. Through this event colleagues get to know each other better, which creates and strengthens internal connections and accelerate internal networking. By improving understanding of each other’s services, cross-sell opportunities emerged naturally. The relaxed setting made it easier for teams to reach out and collaborate across departments, which continued long after the training.
