1. What is Quality Score?

The Quality Score is a metric that converts pass rate percentage into a score from 0 to 100. It's commonly used in quality control for small battery-operated calculators.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Pass Rate — The decimal value of pass percentage (e.g., 0.95 for 95%)

Explanation: The formula converts the decimal pass rate to a percentage score.

3. Importance of Quality Score

Details: Quality Score provides a standardized way to compare product quality across different production batches and manufacturing facilities.

4. Using the Calculator

Tips: Enter the pass rate as a decimal between 0 and 1 (e.g., 0.95 for 95% pass rate).

5. Frequently Asked Questions (FAQ)

Q1: What is a good Quality Score?
A: Typically, scores above 90 are considered good, above 95 excellent, and below 80 may indicate quality issues.

Q2: How is pass rate determined?
A: Pass rate is calculated by dividing the number of units passing QC by the total number of units tested.

Q3: What affects Quality Score?
A: Manufacturing consistency, component quality, and testing standards all impact the score.

Q4: Should this be used for all products?
A: This simple metric works well for basic products like small calculators, but complex products may need more sophisticated metrics.

Q5: How often should Quality Score be calculated?
A: For consistent monitoring, calculate for each production batch or at regular intervals (weekly/monthly).
