- Control limits (upper and lower) for detecting out-of-control conditions
- Center line representing the process average
- Tools for identifying trends, shifts, or fluctuations
- Applicable across manufacturing, service industries, and project management
- Supports decision-making for process improvements
Pros
- Provides real-time insights into process stability
- Helps prevent defects and reduce waste
- Facilitates data-driven decision making
- Widely applicable across various industries
- Simple to interpret once understood
Cons
- Requires proper statistical understanding to implement effectively
- Can be misused if control limits are set improperly
- Not suitable for small sample sizes or non-stationary processes
- May lead to over-adjustment if false alarms occur
