Analysis of Problems
• Tools which are used to obtain and structure ideas during the cycle

• Tools that are used to gather and analysis numerical data during the cycle.
The 5 Principles :-
• Problem Definition
• Identify Root Cause
• Customer Protection and Countermeasure(s)
• Confirm Effectiveness of Countermeasure
• Feedback / Feed forward
The different types of problem solving
• This looks at putting in place solutions prior to abnormalities occurring. Best identified during the design stage prior to transfer to manufacturing using Advanced Quality Tools.
• This looks at the current standards and by analysing data using the 7 quality control tools seeks to make kaizen improvements.
• This looks at the abnormalities that have occurred and by gathering and analysing data using some of the 7 quality control tools aims to provide a customer protection and countermeasure .
