4.6 Planning & Managing Quality
Key Takeaways Explain This Topic AI
Quality is defined as the degree to which a set of inherent characteristics fulfills requirements - it is about meeting requirements, not exceeding them
Cost of Quality (COQ) includes Cost of Conformance (prevention and appraisal) and Cost of Nonconformance (internal and external failure costs)
The 7 Basic Quality Tools are: cause-and-effect diagrams, flowcharts, check sheets, Pareto diagrams, histograms, control charts, and scatter diagrams
Prevention costs (training, planning) are less expensive than appraisal costs (testing, inspection), which are less expensive than failure costs (rework, warranties)
- Quality management follows the principle: plan quality into the project rather than inspect it in
- Last updated: January 2026
Quality management is about ensuring the project produces deliverables that meet requirements and satisfy stakeholder expectations. The focus is on prevention rather than inspection - building quality in rather than inspecting defects out.
Quality Management Processes
- Process Purpose Key Output
- Plan Quality Management Identify quality requirements and standards Quality Management Plan
- Manage Quality Translate quality plan into executable activities Quality Reports
- Control Quality Monitor and record quality results Verified Deliverables
- Quality vs. Grade
- Concept Definition Example
- Quality Degree to which characteristics fulfill requirements A product works as specified
- Grade Category assigned based on functional use Business class vs. economy class
- Low quality is always a problem (defects, rework, customer dissatisfaction)
- Low grade may be acceptable (a basic product that works as designed)
- Cost of Quality (COQ)
- Cost of Quality = Cost of Conformance + Cost of Nonconformance
- Cost of Conformance (Good Money)
Investment to prevent failures from occurring:
- Category Description Examples
- Prevention Costs Preventing defects before they occur Training, planning, process documentation, equipment
- Appraisal Costs Evaluating products for quality Testing, inspection, audits, quality reviews
- Cost of Nonconformance (Bad Money)
Costs incurred due to failures:
- Category Description Examples
- Internal Failure Costs Defects found before delivery Rework, scrap, re-testing
- External Failure Costs Defects found by customer Warranties, returns, lawsuits, lost reputation
- COQ Principle
- Prevention is cheaper than inspection, which is cheaper than failure. LEAST COSTLY MOST COSTLY
- ↓ ↓
- Prevention → Appraisal → Internal Failure → External Failure
- COQ Example
- Category Amount % of Total
- Prevention $50,000 10%
- Appraisal $100,000 20%
- Internal Failure $150,000 30%
- External Failure $200,000 40%
- Total COQ $500,000 100%
The goal is to shift spending toward prevention to reduce overall COQ.
Quality Management Plan
The Quality Management Plan describes how quality policies will be implemented:
- Component Description
- Quality Standards Standards and regulations to follow
- Quality Objectives Measurable quality goals
- Quality Roles Responsibilities for quality activities
- Deliverables Subject to Review What will be inspected or tested
- Quality Control Activities How quality will be verified
- Quality Tools Techniques and tools to be used
- The 7 Basic Quality Tools
These tools, originally proposed by Dr. Kaoru Ishikawa, are fundamental for quality management:
1. Cause-and-Effect Diagrams (Fishbone/Ishikawa)
Identifies potential causes of problems:
- Structure : Problem at the "head," major categories as "bones"
- Categories : Often use 6Ms - Manpower, Methods, Materials, Machines, Measurement, Mother Nature (Environment)
- Purpose : Root cause analysis using "5 Whys"
- 2. Flowcharts
Shows process steps and decision points:
- Purpose : Visualize processes, identify waste or problems
- Use : Process improvement, documentation
- 3. Check Sheets (Tally Sheets)
Structured form for collecting data:
- Purpose : Collect data consistently
- Use : Defect tracking, frequency analysis
- 4. Pareto Diagrams (80/20 Rule)
Bar chart showing problems in descending order:
- Principle : 80% of effects come from 20% of causes
- Purpose : Prioritize problems to address first
- Use : Focus improvement efforts on biggest issues
- 5. Histograms
Bar chart showing distribution of data:
- Purpose : Visualize data patterns and variation
- Shows : Central tendency, dispersion, shape of distribution
- 6. Control Charts
Monitor process stability over time:
- Element Purpose
- Center Line Mean or target value
- Upper Control Limit (UCL) +3 standard deviations
- Lower Control Limit (LCL) -3 standard deviations
Rule of Seven : 7 consecutive points on one side of the mean (but within limits) indicates the process is out of control.
7. Scatter Diagrams
Plot two variables to show correlation:
- Purpose : Identify relationships between variables
- Shows : Positive, negative, or no correlation
- Additional Quality Tools
- Design of Experiments (DOE)
Statistical method for identifying optimal conditions:
- Tests multiple variables simultaneously
- Identifies which factors most affect results
- More efficient than one-at-a-time testing
- Statistical Sampling
Inspecting a subset rather than 100% of items:
- Sampling Type Description
- Attribute Sampling Conforming/not conforming (pass/fail)
- Variable Sampling Measuring on a continuous scale
- Quality Metrics
Quality Metrics define what will be measured and how:
- Metric Type Example
- Defect Rate Number of defects per 1000 units
- Customer Satisfaction Survey score (1-10 scale)
- Process Compliance % of processes followed correctly
- Rework Rate % of work requiring rework
- On-Time Delivery % of deliverables delivered on time
- Manage Quality vs. Control Quality
- Manage Quality Control Quality
- Translates plans into executable activities Monitors and records quality results
- Process-focused Product-focused
- Audits and process analysis Inspection and testing
- Continuous improvement Verification of deliverables
- Proactive Reactive
- Quality Principles
- Key Quality Concepts
- Principle Description
- Customer Satisfaction Meet customer requirements
- Prevention over Inspection Build quality in, don't inspect it in
- Continuous Improvement Kaizen - always seeking to improve
- Management Responsibility Leadership must support quality
- Cost of Quality Invest in prevention to reduce total cost
- Quality Gurus and Concepts
- Guru Key Concept
- Deming Plan-Do-Check-Act (PDCA), 14 Points
- Juran Quality Trilogy (Planning, Control, Improvement)
- Crosby Zero Defects, Quality is Free
- Ishikawa 7 Basic Quality Tools
- Key Takeaways
- Quality is meeting requirements, not exceeding them
- Cost of Quality = Conformance + Nonconformance costs
- Prevention is cheaper than inspection or fixing failures
- The 7 Basic Quality Tools are essential for quality management
- Manage Quality is proactive; Control Quality is reactive
- Quality should be planned and built in , not inspected in
