Question 1

Which five components make into Kaizen?

Accepted Answer

Teamwork, Personal Discipline, Improve Morale, Quality Circles, Suggestions for Improvement

Answer

Kaizen is a Japanese philosophy focused on continuous improvement, involving everyone from top management to the shop floor. Its five foundational components, often referred to as its core principles, include fostering teamwork, promoting personal discipline, improving morale, utilizing quality circles for problem-solving, and encouraging suggestions for improvement from all employees. This holistic approach drives incremental positive changes.

Question 2

What are the five principles of lean?

Accepted Answer

Identify Value, Map the Value Stream, Create Flow, Establish Pull, Seek Perfection

Answer

The five core principles of Lean methodology, as articulated by Womack and Jones, provide a framework for creating maximum value for the customer with minimum waste. They involve first identifying what truly adds value from the customer's perspective, then mapping the entire value stream to identify waste, ensuring a smooth flow of value-adding steps, establishing a pull system where work is initiated only when demanded, and continuously seeking perfection in all processes.

Question 3

Accurate measurement is achieved when:

Accepted Answer

the measured value has little deviation from the actual value.

Answer

Accuracy in measurement refers to how close a measured value is to the true or actual value of the quantity being measured. A measurement is considered accurate when the difference between the observed result and the true value is minimal. This is distinct from precision, which refers to the consistency or reproducibility of measurements.

Question 4

Approximately 68% of the data in a normal distribution will fall within:

Accepted Answer

+/- 1 standard deviation

Answer

According to the empirical rule (or 68-95-99.7 rule) for normal distributions, approximately 68% of the data falls within one standard deviation of the mean. This means that if you go one standard deviation above and one standard deviation below the mean, you will encompass about 68% of all data points. This rule is fundamental for understanding data spread in statistical analysis.

Question 5

The Risk Priority Number (RPN) in an FMEA exercise is determined as follows:

Accepted Answer

severity x occurrence x detection

Answer

In a Failure Mode and Effects Analysis (FMEA), the Risk Priority Number (RPN) is a quantitative assessment used to prioritize potential failure modes. It is calculated by multiplying three factors: Severity (how serious the effect of the failure is), Occurrence (how frequently the failure is likely to happen), and Detection (how easily the failure can be detected before it reaches the customer). A higher RPN indicates a higher priority for corrective action.
