Six Sigma Methodology at Verso Measure CTQ Tools




Verso Six Sigma Article 12

Measure Six Sigma

In the preceding article, we offered an overview of the CTQ and its associated tools. Now, we shift our focus to a more comprehensive exploration of the CTQ Tools within the Measure phase.


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


Pareto:

Originating from the Italian economist Vilfredo Pareto, the Pareto Principle states that 80% of wealth is owned by 20% of the population. Applying this principle to problem-solving, we ask:


  • What 20% of sources are causing 80% of the problems (80/20 Rule)?

By identifying these key factors, we can strategically focus our efforts where they will yield the greatest improvements.



80/20 rule


Fishbone:

Originating from Prof. Kaoru Ishikawa in 1943, initially used at Kawasaki Steel Works, the Fishbone Diagram illustrates the hierarchical relationship between causes and the outcome under study. Its application varies across industries:

In the Service Industry, it encompasses the 8Ps: People, Product/Service, Price, Promotion, Policies, Processes, Procedures, and Place/Plant/Technology.

In the Manufacturing Industry, it revolves around the 6Ms: Manpower, Machine, Methods, Measurements, Materials, and Mother Nature (environment).
