Quality by Design

Quality by Design is a concept around doing sound science in the delivery of innovative medical treatments

Quality by Design (QbD) is a concept that has defined a harmonized pharmaceutical quality system applicable across the life cycle of the product emphasizing an integrated approach to quality risk management and science. QbD is a systematic approach to pharmaceutical development that emphasizes the importance of understanding the product and process. It focuses on building quality into the product from the outset, rather than testing for quality at the end of production. The key principles of QbD include:

  • Understanding the Product and Process: Thoroughly characterizing the product and its intended use, as well as understanding how the manufacturing process affects product quality.
  • Defining Quality Attributes: Identifying critical quality attributes (CQAs) that need to be controlled to ensure the desired quality of the final product.
  • Risk Management: Employing risk assessment tools to identify and mitigate risks associated with the product and process.
  • Design Space: Establishing a defined range of conditions under which a process can be expected to operate consistently and produce a quality product.
  • Continual Improvement: Incorporating feedback and data from manufacturing and quality control to optimize processes over time.
