Most of the time this is thought about as having special items brought in for a team to accomplish. Or perhaps it is thought about as a special seminar for the team. But exercises are excellent if they are done thoughout the year. These are not the normal practicing or day to day activities. They are events that are thought up to stregthen the team.
It may be a project that is short term that the whole team works on or just a few members of the team. It may be one member taking care of the maintenance of equipment. Another member that schedules certain parts of the day. It could be reorganing the office with figuring out how to make it more efficient or easier to work in. It could be geting the team together to have a brainstorming session on how to solve problems.
The suggestion is to think of different ways to have the team work together so it becomes a habit with each member expecting this. Yet it becomes something that simply occurs becuase of going through the exercises over and over.
