Focus the Improvement
To achieve the maximum improvement, we must first focus the improvement efforts. "If I put you in a room with 50 rabbits, you will never catch all of them, but if I send them in a few at a time, you will catch all the rabbits."
We can't do everything so we must focus on the 20% that will give 80% of the return on investment. Quality planning is driven by the voice of the customer. Have you used surveys ,focus groups, and complaints to gather the Voice of the Customer?
