However, in many quality applications errors occur in different forms and time frames:
- Some errors occur sporadic, i.e. only occasionally
- Some errors show a clear trend over the last days or weeks
- Others are critical in terms of total numbers.
The EIT IVE project uses data analytics to address this issue and highlight errors that “fly under the pareto radar”. The following parameters are calculated from rework data sets:
1. Frequency of occurrence
3. Infrequency (sporadic)
4. Time effort for rework
To make the results available in operations, an overall error score is calculated and displayed to operators in rework and in line. This helps identify critical quality issues that lead to rework efforts and thus reduce these efforts.
