Question

A customer has recently tightened the specs for a part your company supplies. The specs are now much tighter than the machine being used for the job is capable of. Briefly, how identify alternatives you might consider to resolve this problem. (See Figure 10.15C)

### Understanding Process Capability and Specifications

**Figure 10.15: Process capability and specifications may or may not match**

This figure consists of three separate graphs demonstrating the relationship between process variability and specifications. It illustrates how process variability can align with, fall within, or exceed specified limits. Each graph has a bell-shaped curve representing process variability with two vertical lines indicating the lower and upper specifications.

#### A. Process Variability Just Matches Specifications
- **Description**: 
  In the first graph (A), the bell curve spans the entire distance between the lower and upper specification limits.
- **Explanation**: 
  The process variability just matches the specifications, implying that the process performance is on the edge of the acceptable range. Any small shift in variability could lead to products falling outside the specification limits.

#### B. Process Variability Well Within Specifications
- **Description**: 
  In the second graph (B), the bell curve is located well within the lower and upper specification limits.
- **Explanation**: 
  This indicates good process control where the variability is significantly within the acceptable range. This scenario represents a robust process with lesser chances of production defects.

#### C. Process Variability Exceeds Specifications
- **Description**: 
  In the third graph (C), the bell curve exceeds both the lower and upper specification limits.
- **Explanation**: 
  Here, the process variability is larger than the allowed specifications, meaning that a significant amount of output will fall outside the acceptable range. This scenario signals a need for process improvement to reduce variability and ensure outputs meet the specification limits.

Understanding and managing process variability is crucial for ensuring product quality and consistency. The graphs in Figure 10.15 provide a visual representation of different scenarios in process capability, helping to identify where improvement efforts may be necessary.
