A critical to quality (CTQ) is the flowchart process of identifying quality features or characteristics in regard to the customer and to identify the problems. This is the process of analyzing the inputs and outputs and find out the path that influence the standard or quality of process outputs. CTQ analysis consists of the physical measurement of height, width, depth and weight. They depict the necessities of quality but have deficiency in the specificity to be measurable.
“Six Sigma - Critical to Quality” aims to provide innovative solutions to improve quality and also management to amend within the small and medium enterprises (SMEs). The flowchart of critical to quality helps in the process of finding out quality features of the product keeping in view the customer and also with the outlook to categorize the problems. Put simply, critical to quality determines the inputs and outputs of processes and find out the path that influence the standard or quality of process outputs. CTQ analysis consists of the physical measurement. The physical measurements depict the requirements of quality and also have insufficiency in the particularity to be measurable.
The unit that is produced under restriction is really worthy. Even if it is lost, additional constraints time must be used to replace or rework it. As constraints time determines net profits of the entire system, the loss goes beyond what is found on the data and rework reports. CTQ projects done under restricted time period attain priority at its zenith
Process of Implementation of CTQ:
- CTQ is used to find out the quality features or characteristics, which are related to the customer.
- It must be included while drawing a detailed flowchart of a business process.
- The flowchart developed by CTQ identifies problems as well as finds out their root causes.
- It also uses to create development in a process.
The critical to quality concept is an essential part of six sigma projects. CTQs are developed in order to fulfill the needs of valuable customers. Customer satisfaction is a primary factor in the development of CTQ parameters. Considering the cost, one may remain focused to customer needs at the initial stage. The performance level of CTQ should be at such a level that it may meet the requirement of the customer. They harmonize improvement or design efforts in tune with customer requirements.
CTQs (Critical to Quality) analyze the characteristics of the service or product that are termed by both the internal and external customer. They may include the upper and lower specification limits or any other factors related to the product or service. According to the interpretation of a valued customer, a perfect CTQ analysis is an actionable and qualitative business specification methodology.
Steps to Find Critical to Quality:
- Critical to quality is implemented when the quality of output is affected.
- It is applicable where an input determines what happens next in the process.
- It is usually applied for measuring whether inputs or outputs are meeting needs.
It is recommended to create a critical to quality tree in order to describe the requirements of a customer in particular manner.
Advantages of CTQ Tree are:
- It helps in transforming unspecific customer requirements into precise requirements.
- It aids sigma teams in detailing broader specification.
- It gives assurance that all the characteristics of the requirements are to be fulfilled.
Steps to Implement and also create a CTQ Tree:
- Determine the Basic Requirement of the Customer: Initially, the sigma team finds out the basic requirement of the customers for the service or the given product. Generally, this basic requirement is pointed out in the comprehensive terms in order to accomplish the requirement of the customer.
- Identify the First level of Requirements of Customers: Secondly, the sigma team finds out two or three requirements that can solve the basic customer's need mentioned in the initial stage of the critical to quality tree. This ensures that the phones are responded instantly by the professionals.
- Identify the Customer's Second Tier of Requirements: Thirdly, again the sigma team finds out three or two requirements which can solve the basic customer's need mentioned in the second stage of the critical to quality tree. This ensures that the professionals are available round-the-clock to respond to the queries of the customers.
- Bring to an end when the Quantifiable Requirements Reaches the limit: The fourth step is implemented when the team arrives at the requirement which can easily be measured.
- Confirm Final Requirements with the Customers: The last step is applicable when all the needs on the Critical to Quality tree reach a standard level after due confirmation with the customer.
