A. Identify waste and find out that most often occurs in the production process.
2. Identify and find the cause of waste that affect product quality.
3. Identify and compare the results of the causes of potential failures, the FMEA method and the method MAFMA.
4. Provide recommendations for improvement that aims to improve quality.
