Problem Solving

Problem solving can take many forms but, if you try problem solving without any structure, you may end up with a bigger problem. 6 sigma training

Definition of Problem :

l Something that needs a solution.

l Can be either positive or negative.

Frequencies:

Chronic - Ongoing and Accepted problems

Spasmodic - Sudden change to normal process.

Problem Levels

l Level 0 - Abnormality only affecting those directly related to the process and contained.

l Level 1 - Abnormality that affects the processes ability to achieve Q,C and D.

l Level 2 - Abnormality that affects the next process and may have an impact on the final customer.

l Level 3 - Abnormality that has affected the final customer.

The different types of problem solving

l Preventative:

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.

l Pro- active:

This looks at the current standards and by analysing data using the 7 quality control tools seeks to make kaizen improvements.

l Reactive:

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 .
