Critical To Quality (CTQ) is a concept that is widely used in the manufacturing and design industries to ensure that products and services meet the needs and expectations of customers. It is a methodology that focuses on identifying the most critical aspects of a product or service that impact its overall quality and performance. By understanding these critical factors, businesses can prioritize their efforts and resources to optimize the quality of their products and services. One key aspect of CTQ is its focus on customer needs and requirements. By understanding the specific needs and preferences of customers, businesses can tailor their products and services to meet those needs and exceed their expectations. This requires a deep understanding of the customer, their needs, and their pain points, as well as an ability to translate those needs into specific product or service features. Another important aspect of CTQ is its emphasis on data-driven decision making. By collecting and analyzing data on product performance, customer feedback, and other key metrics, businesses can identify areas for improvement and make informed decisions about how to optimize their products and services. This requires a robust data infrastructure and a culture of data-driven decision making, where decisions are based on hard evidence rather than intuition or guesswork. Finally, CTQ requires a commitment to continuous improvement. By constantly monitoring and analyzing product performance, customer feedback, and other key metrics, businesses can identify areas for improvement and make iterative changes to optimize their products and services. This requires a culture of experimentation and a willingness to take risks and try new things in pursuit of better outcomes.

The concept of Critical To Quality (CTQ) has its roots in manufacturing and was developed as a way of ensuring processes are designed to achieve the desired quality of the product or service. In the context of design, CTQ can be used to identify and prioritize the features and characteristics of a design that most affect its overall quality and performance. By analyzing the factors that influence how well the design meets its requirements and users’ needs, designers can more effectively apply their efforts in areas that will result in a more successful product. The four CTQ parameters that are most commonly used in design include: aesthetics, usability, cost, and reliability. Aesthetics refer to the attractiveness of the design and its ability to meet the aesthetic goals of the user. Usability includes factors such as how easy it is for users to use the product, how intuitive the design is, and how user friendly it is. Cost considerations include the cost of materials, labor, and engineering to develop the design. Finally, reliability encompasses the ability of the design to perform its intended function over time as desired by the user.

Critical To Quality (CTQ) is a concept focused on identifying and managing customer needs and requirements in order to deliver the desired outcomes of a product or service. It is a model used to prioritize the customer needs in all aspects of a company's operations and activities, from design, production and delivery, to customer service and satisfaction. CTQ is based on the concept of customer requirements and preferences as the main focus of all business decisions. The model focuses on understanding customer needs, prioritizing them and creating a plan to deliver the desired outcomes. The aim of CTQ is to provide customers with the best possible experience, by meeting their needs and exceeding their expectations.
