The PlanDoCheckAct (PDCA) cycle is a disciplined and systematic method for problem solving and ongoing improvement. The PDCA cycle is still followed in practise when steps for a process are outlined linearly.
A prepared plan based on a product, process, problem, or change that has to be improved ...
The PPM approach compares total defects to the total sample size and normalizes the data to a standard rate in order to evaluate a process = ( defective units / total sample size ) x 100
The overall sample size is equal to the sum of the defective and passed units.
A defective unit is one t...
What
to maintain control over internal production procedures and goods.
Why
• To keep track of process or component variability across the short and long terms.
• To make sure the PDCA process is being used to monitor the Quality plan.
• To look for trends, variations, and adjustments in part measurement...
What
Measuring a process's inherent variance (bell-shaped curve) is part of a process capacity study. Process capacity, which is the process's six standard deviation (6s) spread, is a function of a process's variation. Cp and Cpk are two indexes that are frequently used to compare process variance an...
