Where are we going? • What is a problem anyway? • Problem Solving Methodologies • Using DMAIC as a Model • One Powerful Technique
Problem What is a problem, anyway?
What is a problem anyway? • prob·lem/ˈpräbləm/Noun: 1.A matter or situation regarded as unwelcome or harmful and needing to be dealt with and overcome. • 2.A thing difficult to achieve or accomplish.
What is a problem anyway? • Can we separate problems from causes and solutions? It isn’t easy.
Some Problems are Difficult • Lack of clarity • Multiple goals • Complexity • Dynamics
