Before the day of team building arrives, you should have a clear picture of what you expect to learn. In fact, the objectives from the team building day should have been established by you before you went ahead and booked the event.
All the staff participating in the team building day should have a clear understanding of what the day is going to involve. This way, they will know what clothes they will need, among other things, and give them time to organise their home life accordingly. Ideally, every effort should be made to ensure they understand that though the team building day is a test, it is not a test in the sense of pass or fail, but rather to discover how well the team performs.
Of course not all tests are related around team based events, some are tailored for individuals, others are personality based tests, more to discover limits and insights. The scope for the team building day is limitless in terms of what it can offer to companies and organisations.
The team building day could well be a day "away from the office", if a well deserved rest is needed. These always go down well among staff, as it is seen as a treat from the company or organisation.
Many companies and organisations use team building days as an invaluable tool to increase efficiency, and promote camaraderie between team members, who inevitably bring the positives from a team building day back to the workplace.
