Unlocking Customer-Centric Products: The Power of Quality Function Deployment
In today’s competitive market, creating products that meet customer expectations is crucial for success. Quality Function Deployment (QFD) is a powerful methodology that prioritizes the voice of the customer (VOC) throughout the product development process. By gathering customer opinions, QFD turns insights into a satisfactory product for prospects.
Understanding QFD
QFD was created in the 1960s by Yoji Akao and Shigeru Mizuno to effectively translate VOC into specific product features. It serves as a framework for identifying significant product features through meticulous analysis of customer feedback. Global companies like Ford, Toyota, General Motors, AT&T, and Hewlett-Packard have adopted QFD, and it has been integrated into the ISO 16355 standard.
Key Components of QFD
Before diving into the detailed process of QFD, it’s essential to understand its key components. These foundational components empower you to analyze and prioritize customer requirements.
- House of Quality: A core tool of QFD, containing several “rooms” that create a house-shaped matrix. The rooms include customer requirements, competitive analysis, technical or engineering specifications, relationship matrix, potential conflicts, and importance rating.
- Voice of the Customer (VOC): Summarizes customers’ needs, wants, preferences, and desires associated with a product or service. To develop the VOC, you need to create a solid market research report using methods like surveys, user interviews, focus groups, reviews, feature requests, sales feedback, and product analytics.
The 4 Phases of Quality Function Deployment
While there may be variations in the QFD methodology, the four phases below comprise the closest thing to a standard model:
- Product Planning: Begins with gathering customer feedback to develop the VOC. Identify control factors, which are usually technical requirements, and recognize the relationship between the VOC and technical specifications.
- Product Development: Technical requirements move to the left side of the house of quality matrix, and a new set of control factors are put on top. The goal is to recognize the key parts or specs to build a feature.
- Process Planning: Based on the product and component specifications found in the previous phase, this section identifies processes necessary to build features and deliver functionality.
- Process Quality Control: Designed to help you identify the best way to check the quality of the processes identified in the previous phase.
Practical Example of a QFD Implementation Process
Here’s a step-by-step example of how a product team can implement the QFD methodology:
- Develop the VOC by gathering customer feedback.
- Identify key features and assign weighted scores.
- Add control factors and conduct competitor analysis.
- Identify relationships using the relationship matrix.
- Review interrelationships and calculate importance ratings.
- Move to the next QFD phase.
Frequently Asked Questions about QFD
- What is the meaning of QFD? QFD stands for quality function deployment, a structured framework to turn customer feedback into actionable technical requirements.
- What are the phases of QFD? There are four phases of QFD, which have a waterfall effect.
- What is QFD in Six Sigma? Six Sigma uses QFD as part of its methodology to prioritize customer needs and enhance product quality.
- What is an example of QFD? An example of QFD is a family-friendly vehicle, where a product team gathers feedback from the targeted audience about what they want in their family’s vehicle.
- What is the purpose of QFD? The purpose of QFD is to gather customer feedback and discover the product features that are most important to them.
Conclusion
Quality Function Deployment ensures the VOC is prioritized throughout the product development lifecycle. It positions customer needs and preferences as the driving force in creating a product suite that meets their expectations. By aligning customer needs with technical requirements, QFD helps build successful products that satisfy customers.
