Summary of Quality Management and TQM in Business
Quality Management and TQM in Business: A Student Guide
Introduction
Quality management helps businesses make products and services that meet standards and customer needs. This guide breaks down core concepts, explains Total Quality Management (TQM) elements (except Continuous Improvement and Customer Satisfaction which are covered elsewhere), and shows how quality systems and practices work in real businesses. Practical examples and short definitions are included to help you learn and remember key ideas.
1. Core quality concepts — simple parts
What is quality?
Quality: The ability of a product or service to satisfy specific needs and meet set standards consistently.
- Quality is judged by factors such as appearance, reliability, durability, and after-sales support.
- Example: A smartphone with long battery life, a strong screen, and reliable software is considered high quality.
Quality control (QC)
Quality control: A system that checks the final product to ensure it meets required standards.
- Focus: Inspect finished goods and identify defects before products leave the factory.
- Activities: final inspections, sampling tests, performance checks.
- Example: Testing a sample of bottled drinks for correct volume and seal integrity before shipping.
Quality assurance (QA)
Quality assurance: Processes and checks performed during and after production to ensure standards are met throughout.
- Focus: Prevent defects by building correct processes and monitoring every stage.
- Activities: process audits, standard operating procedures (SOPs), employee training on methods.
- Example: Using a checklist at each assembly station so errors are caught immediately rather than at the end.
Quality management
Quality management: The set of activities used to ensure the business produces products or services of consistently high standard.
- Focus: Tools and techniques to design and maintain product quality and to assign accountability across functions.
- Example: A company using documented procedures and regular performance reviews to keep product quality stable.
Quality performance
Quality performance: Measurement of each department’s results against agreed quality standards.
- Focus: Evaluate outcomes (products, processes, customer feedback, statistics) to see if standards are met.
- Example: The production department measures defect rate per 1,000 units; the finance team tracks cost of rework.
2. Comparing QC and QA
| Quality Control (QC) | Quality Assurance (QA) |
|---|---|
| Inspects finished products to find defects before delivery. | Checks and improves processes so defects are rare or prevented. |
| Ensures finished products meet standards. | Ensures standards are met at every stage of production. |
| Uses tests and inspections on output. | Uses process design, documentation, and training. |
| Corrects problems after they occur (detect and fix). | Aims to get it right the first time (prevent problems). |
| Examples: sampling tests, final inspection. | Examples: SOPs, process audits, staff training. |
3. Comparing quality management and quality performance
| Quality Management | Quality Performance |
|---|---|
| Tools and techniques to design and control product/service quality. | The measured results of departments against quality standards. |
| Focuses on methods and accountability across business functions. | Focuses on outcomes like defect rates, product tests, and user surveys. |
| Example: Implementing process documentation and training. | Example: Reporting monthly defect percentages per department. |
4. Quality management systems (QMS)
Quality management system: A framework a business uses to manage key organisational processes to achieve quality objectives.
- Purpose: Document processes, assign responsibilities, and provide resources to meet quality goals
