Which tool is specialized for translating general customer requirements into specific requirements?

1. Quality function deployment

2. Kano analysis

3. Affinity diagram

4. Critical to quality tree

The correct answer is: Critical to quality tree

The specialized tool for translating general customer requirements into specific requirements is Quality Function Deployment (QFD). QFD is a structured approach that takes broad customer needs and translates them into detailed product and service specifications. This process often involves creating a matrix known as the "House of Quality," which visually represents the relationship between customer demands and how those demands are addressed in the design and development stages. This tool focuses on ensuring that customer voices are not just heard but also effectively incorporated into the development process by linking customer desires with relevant engineering characteristics. By doing so, QFD fosters a thorough understanding of the requirements that must be met to ensure customer satisfaction and ultimately guides teams in prioritizing features and functions that align with customer expectations. In contrast, Kano analysis is used to categorize customer preferences and prioritize features based on their impact on customer satisfaction but does not directly translate those requirements into specific design criteria. The affinity diagram is a brainstorming tool that organizes ideas and insights into relevant groups but doesn't focus specifically on translating customer needs into requirements. The critical to quality tree identifies which aspects are crucial for quality but does not encompass transforming general needs into detailed specifications.
