5. SPC (Statistical Process Control)
SPC monitors stability and signals special cause variation before customers feel pain. Control charts, capability, and disciplined reaction plans keep processes centered and predictable.
Why It's Important
It turns noise into knowledge. Early warnings cut scrap, rework, and warranty, while boosting throughput and confidence.
How to Improve SPC (Statistical Process Control) Skills
- Start with MSA: A shaky measurement system ruins SPC. Validate bias, linearity, stability, and GR&R first.
- Choose the right charts: X̄-R, X̄-S, I-MR, p, np, c, u—select based on data type and subgrouping logic.
- Use rational subgrouping: Group data so within-subgroup variation reflects common cause only.
- Calibrate control limits to process: Avoid tampering; recalc limits only after validated changes.
- Define reaction plans: Clear roles, timers, and containment when rules trigger.
- Go real-time: Stream data from equipment/MES to flag trends early; close loops fast.
- Tie to capability: Track Ppk/Cpk and entitlement. Improve centering and spread deliberately.
