Understanding the Pioneers of Quality Improvement
To build a strong foundation in quality, it’s important to familiarize yourself with the philosophies and contributions of the early quality gurus. Their teachings often show up as topics in the CQIA exam topics, including principles of process control, leadership in quality, customer focus, and cost of quality.
Walter Shewhart originated the concept of Statistical Process Control (SPC) and introduced the Plan-Do-Check-Act (PDCA) cycle, which remains fundamental for continuous improvement efforts. His work emphasized data-driven control of processes rather than inspection alone, guiding how processes can be monitored for consistent quality.

Why These Are Essential for Your CQIA Exam and Practical Work
These quality pioneers’ teachings are not just historical footnotes; they are the DNA of quality improvement today. Understanding these basics helps you approach exam questions with clarity and also enables you to contribute effectively when working in teams or leading small quality initiatives.
In the CQIA exam, questions will often test your knowledge of these concepts, their practical tools, and their applications in real-world scenarios—such as how to use PDCA for problem-solving or how leadership impacts quality culture. Being fluent in these principles strengthens your ability to analyze quality challenges and identify appropriate solutions.
Moreover, these foundational ideas align with the CQIA Body of Knowledge domains, including continuous improvement techniques, customer-supplier relationships, and problem-solving methodologies. Mastering their core concepts provides the confidence to answer exam questions correctly and to apply quality improvement basics effectively in your workplace.
Real-life example from quality improvement associate practice
Imagine a Certified Quality Improvement Associate joining a cross-functional team tasked with reducing rework in a customer service process. The associate starts by reviewing process data using Shewhart’s control charts to understand variation and identify any signs of instability.
Next, the associate leads the team through a cause-and-effect diagram (Ishikawa) to explore all potential sources of rework, involving frontline staff to gather insights. Using Deming’s PDCA cycle, they test a small process change: standardizing a customer feedback form to reduce data entry errors, a known cause from the fishbone analysis.
The associate tracks impact through data collection on rework rates, demonstrating a measurable reduction. They then prepare a report showing cost savings linked to Crosby’s “quality is free” principle, highlighting how prevention reduces waste and improves customer satisfaction. Finally, the associate presents these results and lessons learned to management, emphasizing total quality involvement aligned with Feigenbaum’s vision.
