What is a Product capability template?
The repeatability and consistency of a production process in relation to client needs in terms of specification limits of a product parameter are known as process capability. This metric is used to objectively assess how well your process meets or fails to satisfy the standards.

Capability indices have been created to visualize that metric graphically. Capability indices allow you to plot your process's distribution against the product specification boundaries. Capability indices should be used to examine if the process is capable of reaching the stated criteria, given its inherent variance. It's also a measure of the product's ability to be manufactured using the supplied techniques.

Benefits of creating a product capability template:
When a process' capacity is recognized and recorded, it may be used to track continuous improvement using trends over time, prioritize process changes, and determine whether or not a process is capable of achieving client needs. Variation in a process may be reduced by implementing process controls, conducting measurements, and using dependable, well-maintained equipment. The procedure may be capable of consistently generating satisfactory results.

How to Create a product capability template?
Determine if the data is continuous or discrete.
If the data is discrete, use the Capability Analysis (Binomial).
Check the process stability if the data is continuous.
The I-MR control chart may be used to verify process stability.
We cannot compute the process capability if the process is not stable; we must correct or alter the data to make it steady.
We examine the process normalcy whether it is steady.
We can determine the Capability for normal data if the data is normal and steady.
If the data is not normal, it must first be normalized; if this is not possible, the Box-Cox transformation must be used.
Calculate the process capability once the data has been restored to normal.

Tips for Creating a Product Capability Template:
Once the process capability is within statistical bounds, it provides long-term performance. It examines the process' ability as well as the abilities of people, machines, measurements, and methodologies.
In manufacturing, there are upper and lower specification limitations for any measurement. In certain businesses, there may be only one restriction, either a maximum or a minimum.
EdrawMax is one such tool that comes with several similar-looking templates that ease your efforts in creating product capability templates.
