Lucas-TVS Quality Engineer Interview Questions and Answers

There are 5 levels in PPAP (Production Part Approval Process).

• PPAP has 5 levels: Level 1, Level 2, Level 3, Level 4, and Level 5.

• Each level represents a different stage of the PPAP process.

• Level 1 includes documentation submission, while Level 5 involves customer approval.

• The higher the level, the more comprehensive the PPAP requirements become.

• PPAP is used to ensure that suppliers meet the quality standards of their c

Cp measures the capability of a process to meet specifications, while Cpk measures the capability of a process to meet specifications considering centering.

• Cp is a short-term capability index, while Cpk is a long-term capability index.

• Cp considers only the spread of the process, while Cpk considers both the spread and the centering of the process.

• Cp is calculated using the formula Cp = (USL - LSL) / (6 * standard devia...read more

• CAPA is a key component of quality management systems.

• It involves identifying the root cause of a problem, implementing corrective actions to address the immediate issue, and preventive actions to prevent recurrence.

• CAPA processes typically include steps like problem identification, investi...read more

The 10:1 rule is a guideline used in quality engineering to determine the sample size needed for statistical analysis.

• The 10:1 rule states that for every 1 defect found, there are approximately 10 defects that have gone undetected.

• It helps in estimating the total number of defects in a population based on the number of defects found in a sample.

• The rule is often used in quality control processes to determine the approp...read more
