## What is my8data?

my8data is a web-based SaaS solution for quality engineers, metrologists and production managers in the manufacturing industry. The platform enables the execution and documentation of statistical analyses according to industry standards (VDA, AIAG, Bosch).

## Key Features

### Measurement System Analysis (MSA)
- **MSA Method 1 (Cg/Cgk)**: Capability verification of gauges using reference standards
- **MSA Method 2 (Gage R&R)**: Analysis of repeatability and reproducibility with multiple appraisers
- **MSA Method 3**: Simplified Gage R&R for automated measurement systems
- **MSA Method 7/7A**: Attribute measurement system analysis using Kappa statistics

### Machine Capability (MFU)
- Calculation of Cm, Cmk, Cp, Cpk
- Normality tests (Anderson-Darling, Shapiro-Wilk)
- Support for multiple distribution types

### Process Capability (PPK)
- Calculation of Pp, Ppk, Cp, Cpk
- Long-term process capability analysis
- Process stability assessment

### Statistical Process Control (SPC)
- Control charts: X̄-R, X̄-S, I-MR
- Automatic calculation of control limits
- Process capability indices Cp, Cpk, Pp, Ppk

### Additional Tools
- **Boxplot / Charts**: Statistical diagrams and graphical evaluations
- **Raw Data Viewer**: Import and analysis of raw datasets
- **Data Generator**: Synthetic test data generation
- **DFQ Converter**: AQDEF/DFQ file conversion

## Key Metrics & Industry Thresholds

| Term | Meaning |
|------|---------|
| Cg/Cgk | Gauge capability indices (Method 1) |
| %GRR | Share of measurement system variation in total tolerance |
| ndc | Number of Distinct Categories (resolution) |
| EV | Equipment Variation (gauge scatter) |
| AV | Appraiser Variation (operator scatter) |
| Cm/Cmk | Machine capability indices (short-term) |
