The Two Dimensions of Quality — Your Prior Blank Spot
These kept not coming. Burn them in.
| Dimension | What It Measures | Example |
|---|---|---|
| Performance Quality | How well the product’s features meet consumer needs | The taste and aroma of Godiva chocolate — it delivers on what premium chocolate promises |
| Quality Reliability | Consistency of quality from unit to unit | Every Marriott hotel worldwide providing the same service standard — not just some of them |
The critical insight: A product can excel on one and fail on the other.
- High performance quality, low reliability = great product, inconsistent manufacturing (luxury goods with high defect rates)
- High reliability, low performance quality = consistent but mediocre (a fast food chain with a reliable but unremarkable product)
TQM targets both. “No defects tolerable” applies to consistency (reliability), but the product must also be worth making (performance).
Exam scenario approach: If the question says “features meet needs,” “does what it’s supposed to do” → Performance Quality. If it says “consistent,” “unit to unit,” “same every time” → Quality Reliability.
Internal vs. External Failures — You Know This, Now Add Precision
| Failure Type | When It Occurs | Cost Level | Examples |
|---|---|---|---|
| Internal | During production, before leaving the facility | High | Rework, scrap, overfilling, rejected parts — costs caught here stay internal |
| External | After the product reaches the customer | Far higher | Recalls, refunds, warranty claims, lawsuits, lost customers, reputation damage |
Why external is worse: every cost is multiplied by the number of affected customers, plus you pay legal costs, plus you lose future revenue from customers who don’t come back. An internal failure costs you money once. An external failure costs you money repeatedly.
The 9 TQM Tools — By Category
Source: TotalQualityManagement
This has never been tested. It will be.
Category 1 — Analysis Tools
| Tool | What It Does |
|---|---|
| 1. Competitive Product Analysis | Disassemble and test a competitor’s product to identify where yours can improve. “Legal industrial espionage.” |
| 2. Value-Added Analysis | Audit every step, material, and process to eliminate activities that consume resources without adding customer value |
| 3. Quality/Cost Studies | Identify where quality-related money is wasted — separates Internal Failures from External Failures by cost |
Category 2 — Process Control & Improvement
| Tool | What It Does |
|---|---|
| 4. Statistical Process Control (SPC) | Uses math to monitor production variance. Two sub-tools: Process Variation Studies (normal range of variance) and Control Charts (early warning when a process drifts toward failure) |
| 5. Quality Improvement (QI) Teams | Cross-departmental employee groups that meet regularly to define, analyze, and solve quality problems |
| 6. Benchmarking | Compare performance to a reference point — Internal (vs. your own past) or External (vs. an industry leader) |
Category 3 — System-Wide Standards & Redesign
| Tool | What It Does |
|---|---|
| 7. ISO 9000 & ISO 14000 | International certification: ISO 9000 = quality management standards; ISO 14000 = environmental performance standards |
| 8. Business Process Re-Engineering (BPR) | Fundamental rethinking and radical redesign from scratch — not incremental tweaks. Used when minor fixes can’t close the gap |
| 9. Getting Closer to the Customer | Systematically gather and act on customer feedback to shape product and service design |
The Quality Wheel (Heskett, 1987)
Quality is a self-reinforcing cycle that starts with people: Satisfied Employees → High-Quality Output → Satisfied Customers → Firm Success → Employee Recognition → back to Satisfied Employees
You cannot have TQM without first attending to employee satisfaction. Quality is downstream of people, not machinery.
