Specification limits are defined by …………..1. Process data2. The customer3. The Master Black Belt4. The supplier

The correct answer is 2. The customer.

Explanation

Specification limits are critical parameters that define the range of acceptable values for a product or service from the perspective of the customer. These limits are established based on customer requirements and expectations regarding quality and performance. Customers communicate their needs through formal specifications, which may include dimensions, tolerances, material properties, and functional capabilities.

While other factors, such as process data, supplier capabilities, or insights from experienced professionals like a Master Black Belt in Six Sigma, can influence the specification limits, they do not define them. Ultimately, the customer's demands and requirements are the primary determinants of these limits, ensuring that the final product meets their needs and expectations in terms of quality and functionality.
