When a problem cannot be solved quickly by an individual, it is necessary to form a Team. The team will engage in the investigation and resolution of the problem. Many factors are critical to establish a group and to ensure that the group can work effectively together. Using a team approach is not just a step in the problem solving process, but an overriding framework for decision making.
It is necessary to reevaluate team membership continually.
Cross-functional teams minimize visible layers of supervision originating solely from any specific functional group - Engineering, Manufacturing, Quality, etc.
A Team is a small group of folks with the process / product knowledge, allocated time, authority and skill(s) in the required technical disciplines to solve the problem and implement corrective actions. The group must have a designated champion.
Team members must be empowered with the potential to ‘change the rules’.
