The ideal tour is experienced as a team. The impact is greatest when two or more people from the same organization have the same experience, develop a common vision and commit together to improve towards it. The ideal size for one group is 15 – 20 people, but significant change can be made by groups of 5 – 10 people. We recommend forming a cross-functional group of leaders and influencers, from among the following:

• Business owners, executives and senior managers
• Functional managers, middle managers, change agents
• Supervisors, union representatives, informal opinion leaders
• Trainers, lean experts, improvement specialists
