Once a problem has beenbought to our attention, a
team must be formed to
tackle the problem.
Ideally, this will be a team
of people with a variety ofskills and knowledge

What action can be taken immediately?
Do we have stocks that need sorting?
Are we still manufacturing parts withthe problem?
Will the actions that we take causeother problems?
D3. Containment Action
