Quality Management for PMP

Quality management is a core Process domain topic. The exam tests your understanding of quality planning, assurance, and control — and the PMI mindset that prevention beats inspection.

The Quality Management Process

1. Plan Quality Management — define quality standards and how to achieve them
2. Manage Quality (Quality Assurance) — ensure processes are followed
3. Control Quality — inspect deliverables against standards

Quality Planning

Define what "quality" means for this project:

• Quality standards — industry, regulatory, organizational
• Quality metrics — defect density, failure rate, customer satisfaction
• Quality checklists — verification criteria
• Quality assurance approach — process audits, reviews

Quality Assurance (Manage Quality)

Quality assurance is process-focused and proactive:

• Ensure quality processes are being followed
• Perform process audits
• Identify process improvements
• Prevent defects before they occur

PMI mindset: Quality is built in through good processes, not inspected in after the fact.

Quality Control

Quality control is product-focused and reactive:

• Inspect deliverables against quality standards
• Identify defects
• Verify deliverables meet requirements
• Use inspection and testing

The Seven Basic Tools of Quality

1. Cause-and-effect diagram (fishbone) — identifies root causes
2. Flowchart — visualizes process steps
3. Check sheet — structured data collection
4. Histogram — shows frequency distribution
5. Pareto chart — 80/20 rule — prioritize the biggest issues
6. Scatter diagram — shows correlation between variables
7. Control chart — monitors process stability over time

Control Charts

A control chart monitors process stability. Key concepts:

• Upper and lower control limits — typically ±3 standard deviations
• Mean (centerline) — average
• Out of control signals:
  • A point outside control limits
  • Seven consecutive points on one side of the mean (rule of seven)
  • Seven consecutive trending up or down

Cost of Quality (COQ)

Category	Description
Prevention costs	Training, process improvement, quality planning
Appraisal costs	Inspection, testing, audits
Internal failure costs	Rework, scrap before delivery
External failure costs	Warranty, recalls, lost customers

PMI mindset: invest in prevention — it's cheaper than failure costs.

Quality Theorists to Know

• Deming — PDCA cycle, 14 points, prevention over inspection
• Juran — fitness for use, quality trilogy
• Crosby — zero defects, "quality is free"
• Ishikawa — cause-and-effect diagram, seven basic tools

The PMI Mindset for Quality

1. Prevention over inspection — plan quality in
2. Process-focused — good processes produce good products
3. Continuous improvement — PDCA cycle
4. Customer satisfaction — quality is defined by the customer
5. Management responsibility — quality starts at the top

Common Quality Exam Traps

• Confusing assurance (process) with control (product)
• Forgetting the rule of seven in control charts
• Picking inspection when the scenario calls for prevention
• Missing that Pareto prioritizes the biggest issues (80/20)

Final Thoughts

Quality management rewards the PMI mindset: prevention, process, continuous improvement. Know the difference between assurance and control, memorize the seven basic tools, and you'll handle quality scenarios with confidence.
