Is this for you?
- Control charts are filled in, but nobody can say what they show.
- Your Cpk looks good, yet customers still find problems.
- Operators adjust the machine after every measurement "to be safe".
- People confuse Cp with Pp, or think they need different data for each.
Who should attend
Quality and process engineers, supervisors, line leaders, and operators who record SPC data. Mixed groups work well: operators collect the data; engineers decide what to do with it.
What participants practise
- Running a live process on the free SPC simulator: centred, off-centre, too wide, tool wear, batch-to-batch jumps, an over-adjusting operator
- Choosing the right chart: I-MR, X̄–R or X̄–S, and why the subgroup matters
- Calculating control limits by hand once, so the software is no longer a black box
- Reading signals: points beyond limits, runs and trends, and what usually causes each
- Cp, Cpk, Pp and Ppk from the same data: why they differ and what the gap tells you
Choose the format
| Format | For | What it covers |
|---|---|---|
| Awareness (4 hours) | Operators, supervisors | What a control chart shows, when to act and when not to |
| Practitioner (1 day) | Engineers, quality team | Chart selection, control limits, signals and capability indices, on the simulator |
| Practitioner (2 days) | Engineers with live data | More chart types and studies, plus your own data from the line |
4 hours includes a tea break; a full day is about 8 hours, with lunch and two tea breaks. This course is also part of the core tools courses. A full review of your own control charts and capability studies is consulting work, not part of the course. Ask us about it.
What changes afterwards
Your team stops reacting to noise and starts reacting to real signals. Capability numbers get calculated correctly and explained correctly to customers.
Questions people ask
Which reference do you follow?
The AIAG SPC reference manual. Please use a licensed copy; Kattamaipu is independent and not affiliated with AIAG.
Do participants need statistics?
No. Basic arithmetic is enough. The simulator does the heavy lifting.
Can you cover attribute charts (p, np, c, u)?
Yes, if they matter for your process.
