Dear Harish,
This in addition to what senior member Mr Nathrao has written.
For the team building activities, tell the members to wear sports shoes. Secondly, they may wear casuals but there is possibility of getting their clothes soiled therefore, they may not wear branded costumes. I say so because, once I was the trainer for outbound training. Occasionally, I found that few members shied away from participating because they felt that their costly T shirt or bermuda or even shoes costing Rs 5,000/- could get soiled. Secondly, tell women staff members not to wear high-heel footwear. No staff member should wear tight-fitting clothes.
In the outbound team building games, there is possibility of someone falling and hurting himself/herself. However, staff members should take their fall sportingly and they should not blame the trainer for causing them injuries.
In the team building games, people go little overboard and sometimes they pass caustic remarks against their colleagues. This in turn sows seeds of discord. Therefore, staff members should maintain decorum.
One more important point is carrying cash and valuables. Women staff members may wear jewellery as minimum as possible. In case if they bring the jewellery, then preferably it should be kept in the room itself. However, for the safety of the jewellery pieces, the individual is responsible.
Last but not the least, since you are making policy, then it merits inclusion on measurement of ROI on such activities as well. In many companies the spirit of the teamwork wears off just after few days or weeks after the outbound event. Therefore, one should be well clear who will measure ROI, how will it be measured and when it will be measured.
Thanks,
