Product Qualification Rate (PQR)
Product Qualification Rate (PQR) measures the percentage of products that meet quality standards and pass the qualification tests during the production or testing phase. This metric is crucial for manufacturing and software development companies to ensure product reliability and customer satisfaction.
HOW TO MEASURE
Calculate PQR by dividing the number of products that pass the qualification tests by the total number of products tested, then multiply by 100 to express it as a percentage.
HOW TO IMPROVE
Enhance Quality Control Processes: Implement more stringent quality control measures and regular audits to identify and correct defects early in the production process.
Employee Training: Invest in training for employees on the latest production techniques and quality standards.
Feedback Loop: Incorporate feedback from the testing phase back into the design and manufacturing processes to prevent recurring issues.
Technology Upgrades: Utilize advanced technologies and equipment that enhance precision and consistency in production.
FORMULA
PQR = ( Number of Products that Pass Qualification Tests / Total Number of Products Tested ) × 100%
EXAMPLE
A software company conducts tests on 100 new software builds, and 90 of these builds meet the specified quality criteria without major bugs or issues. The Product Qualification Rate would be: PQR=(90/100)×100%=90%. This indicates a high level of product quality and readiness for release.
DEPARTMENT USAGE
Engineering: To gauge the effectiveness of development processes and make improvements.
Quality Assurance: To monitor and ensure product quality throughout the testing phase.
Product Management: To make decisions about product readiness and improvements.
Leadership: For strategic planning based on product quality and market readiness.
