Quality assurance is necessary to maintain quality and services in the pharmaceutical and life science industries. Quality assurance demonstrates that the logic and practice of problem solving can integrate both program efficacy and regulatory compliance. This title is divided into three parts; the first part discusses the process by which a problem in regulated industry is identified, for example a manufacturing deviation that leads to an adulterated drug product, and reviews the decision-making steps involved in remedying the problem. The second part delves into the staff training requirements of revised procedures. The third part expands on this discussion by considering piloting the proposed module, preparing assessments of trainee proficiency, evaluating the training module, including integrating rigorous evaluative designs with formative program improvement, and documenting the entire effort.
