If you are not achieving the results you want, you need to get the team involved, and deal with the underlying issues surrounding team effectiveness.
On day 13 you will be meeting with the entire team for the day. Have the room set up with round tables for five people at most per table and have a flip chart and markers next to each table group. If your team is less than 10 people, try to create two groups. If less than five, work with only one group.
After greetings and opening remarks, give each table group a post-it pad and ask each team member to write down a percentage on a post-it, anywhere between 1-100 percent, that reflects how effective you currently are as a team.
Encourage each member of the team to answer honestly. All responses are to be kept confidential. Once each team member's percentage is recorded on a post-it, have them fold the paper and place it in the center of the table.
