The symtom, the desease and the cure

Identify the symptom is useful for understanding the problem and setting priorities to overcome it.

The disease focuses the attention on the underlying causes of the problem.

The cure focuses on the actions to remove the cause and also take into account negative collateral effects.

The lack of understanding of these three concepts is making the execution of a six sigma project to be more complicated than expected.

Why? people are limiting their actions to removing the symptoms.
