Quantitative data is data that can be verified and quantified using numbers. Quantitative data is more defining than qualitative data which is often used as a description.
Quality Engineering is a discipline with the engineering circle that is focused on improving and innovating the all things related to the quality of a process or product. Quality Engineering is an important philosophy to understand within the continuous improvement umbrella.
Qualitative gives reference to the use of "qualities" rather than "quantities."

Quality Function Deployment is a methodology developed by Dr. Yoji Akao. The methodology attempts to accomplish all major requirements of the customer. It does this by identifying the voice of the customer and working to ensure the needs are met or exceeded. QFD is also often viewed as a set of communication and translation tools. QFD tries to eliminate the gap between what the customer wants and what they get.
Quality is the standard by which something is measured and how well it meets those measurements. It is also a speciffic characteristic or attribute of an item or service. When Quality is measured it is typically in terms of how well a product, process or service is meeting the expectations set forth by a customer.
