Six Sigma Methodology at Verso Measure CTQ Tools

Verso Six Sigma Article 14

In the preceding article, we presented a comprehensive overview of the Critical to Quality (CTQ) concept and its associated tools, including Process Mapping, Pareto analysis, and Fishbone diagram. Building upon that foundation, our exploration now extends to the Quality Function Deployment.

CTQ Tools:

Process Mapping – improving efficiencies

Pareto – using the 80-20 rule

Fishbone – getting to the root cause

FMEA (Failure Modes and Effects Analysis) – when the process is critical

Quality Function Deployment – when the customer “wants” are not well defined… “Diffused VOC”

CTQ Drill Down Tree – Alignment with the company’s key goals

Quality Function Deployment – when the customer “wants” are not well defined:

In 1972, the origin of a transformative concept emerged in Japan through the collaborative efforts of Mitsubishi and the visionary professors Mizuno and Akao. This groundbreaking idea aimed to revolutionize the design of an oil tanker by translating the abstract "wants and needs of the customer" into tangible and measurable parameters. The approach involved a strategic shift, focusing on embedding customer satisfaction directly into the design of a product or process. This innovative method sought to convert subjective preferences into concrete, quantifiable criteria, marking a significant milestone in the evolution of product and process design methodologies.

Customer needs

Stay tuned for Article number 15, where we will explore the CTQ Drill Down Tree in greater detail. Our intention is to delve into the intricacies of this tool, providing a comprehensive guide that offers insights into its effective utilization for identifying and prioritizing key elements essential to ensuring the quality and success of processes or products.
