ROI CalculatorQuality by Design is extremely important in industries such as life sciences as far as design, development, and introduction of new products into the market are concerned.
One of the main ideas behind the process is that one should not just test quality of products after they have been delivered, but also prepare products for such testing in advance.
Thus, one of the main aims of QbD is to ensure that all variability is recognized and solved before launching the previously designed product into the market. The end product must conform to the requirements from the beginning, and one should eliminate all deviations from the norm to obtain the product of the needed quality.
QbD can solve several problems connected with finances and resources, sales targets, customer dissatisfaction, and even burnouts in the team due to constant stress.
Quality by Design aids both the customer and the manufacturer. The QbD process is significant because life sciences companies face several challenges in the initial periods of building a new product. These may include gaps between the:
The manufacturer’s understanding of the customer’s needs and the customer’s own understanding
The manufacturer’s understanding of the customer’s needs and the actual product design
Product design and the final execution of the product
Process development assumptions and real-world manufacturing variability
Knowledge held within one team and how it’s communicated across R&D, manufacturing, quality, and regulatory groups.
Quality assurance by design benefits both ends of the manufacturing chain, the customer and manufacturer. The QbD concept is of high importance to life sciences firms since they encounter many issues when constructing a novel product in the early stages of production.
Launched for the first time as an international QbD principle and strategy between 2009 and 2021, the concept has been defined by QbD rules as a "systematic approach to development which starts from a set of predefined goals and aims to result in product and production understanding and control by using high-quality science and risk management."
The QbD procedures are often integrated with the Process Analytical Technology concept, which enables meeting the highest standards of quality for products.
Quality by Design generally comprises five main steps: Define, Discover, Design, Develop, and Deliver.
At the start of the process, the requirements of the end product are defined according to the needs of the customers, safety, and efficacy of the product.
While not defined in ICH guidelines, the following five-step framework summarizes how Quality by Design principles can be applied across the product development stages:
Defining a product quality profile that consists of a quantitative description of the clinical safety of the product along with the product KPI to be followed by the developers.
Making a summary of the available information and identifying knowledge gaps for risk reduction.
The design of the product takes place so that the necessary quality characteristics can be determined in line with the product quality profile.
An adjustable process for the product is developed according to the quality characteristics indicated previously.
Setting an essential specification of the product and its characteristics to receive required results.
An extensive control strategy is determined for the implementation of all aspects of the manufacturing process along with its risk assessment and steps.
Regular auditing of the manufacturing process and making changes to ensure product quality.
