8. The data Source
The production reports data are exported from the ERP (or MES)
The mandatory data
9. The Data in Disco
The Production data are configured and imported to Disco for process discovery
10. The Process in Reality
The actual process is animated based on the production data
To view the animation press here.

11. The Actual Process Model
A visual map displays the flow of the process based on the sequence of operations
Boxes represent the operations
Arcs display the sequence of the operations performed on work orders
Numbers at the arcs and in the boxes represent frequencies of operations and paths
The thickness of the arcs and the coloring of the boxes visually support these numbers.
13. Revealing Deviations from Routing
For some work orders, the process starts with different operations then defined in the
routing (circled in red)
14. Locating the Slow Work Orders
The Performance filter is used to retrieve the desired work orders by duration
15. The Model of the Slow Work Orders
Numbers in the boxes represent the mean duration of the operations
Numbers at the arcs represent the mean idle time between operations.
The thickness of the arcs and the coloring of the operations visually support these numbers.
19. The Process Model by Work Cells
Boxes represent the work cells and the operations done in them
Arcs display the paths of the work orders among the work cells
Numbers in the boxes represent work orders in work cells
Numbers at the arcs represent work orders transferred between work cells
The thickness of the arcs and the coloring of the boxes visually support these numbers.
20. Locating the Longest Idle Times
The Performance filter is used to retrieve the work cells with the longest idle times between
operations
21. Longest Idle Times in Work Cells
The numbers at the arcs represent the longest durations of idle time between operations
in the work cells
The yellow arrow represents a repeating operation in the same work cell.
22. Statistics About Work cells
A statistics display about the work cells with the long idle time
28. The Impact of a Breakdown on a Selected Part
The operation with the ellipse was reported as a breakdown
The red arrow points at a delay in the process (compared to one indicated by the green
arrow)
