FULL DAY TEAM BUILDING EXPERIENCES
If significant team building or management development is needed, then setting aside a full day lays the foundation and makes it clear the purposes are real and time is allocated to get effects.
Humans see a day unit as a logical meaningful period and hence what is done in that period is also seen as meaningful.
So, in addition to giving more time, a day program carries with it a focus and commitment that works. It also allows for consolidation of the learning experience before returning to everyday life/work.
