Critical to Process (CTP)

Critical to Process (CTP) are the key process input variables. These are the process parameters which influences other critical approaches – Critical to Quality (CTQ), Critical to Delivery (CTD) and / or Critical to Cost (CTC). To illustrate CTP in terms of process, we must mention it as the critical x’s in the function -> y […]

Critical to Delivery

Critical to Delivery (CTD) characteristics are services to manufactured goods, and/or transactional characteristics that significantly influence one or more CTSs in terms of Delivery. It represents the customers who have stated needs in relation to delivery. It is of late delivery. However, early delivery might create problem for some of the customers as it may […]

Critical to Cost (CTC)

Critical to Cost (CTC) analysis is the input to the Quality Function Deployment activity designed for the satisfaction of customers’ requirements. This is the process of analyzing the inputs and outputs and find out the path that influence the cost of process outputs. CTC are similar to CTQ but the former deals entirely with the […]

Critical to Quality

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 […]

Critical Path Method

CPM (Critical Path Method) is considered as an important project management technique that regulates the existing projects, plans, schedules and undertakes new and complex projects for various industrial processes. The technique helps management in controlling the work of the project. CPM has twofold streams, one for industrial process and the other military.

Cpk

Cpk Process Capability Index (Cpk) measures the process potential and performance of processes. Process capability evaluates the productivity of an in-control process to the requirement limits by using capability indices. It can be applied only when the output response displays a normal distribution.

Cp

Process Capability (Cp) is the indices used to measure how closely and consistently the process can reach the optimum level of satisfaction of customers. Six sigma is the vast commercial way to drive away errors which are resulted by all processes at levels of performance. It takes in all the possible elements and tools including […]

Correlation

Correlation Correlation has a significant place in six sigma. Correlation measures relation between two or more variables. It investigates the relationship between two quantitative and continuous variables. If the value of one variable increases when the value of the other also increases, they are said to be positively correlated. If the value of one variable […]

Cost of Quality (COQ)

A Cost of Quality (COQ) constructs a chart displaying prevention, appraisal, and failure costs over time in order to demonstrate the cost of poor quality. The Cost of Quality can be categorized into two divisions: The Cost of Poor Quality (COPQ), and The Cost of Good Quality (COGQ). The cost of poor quality looks over […]
