Repair Time

The Repair Time Report in WATS Analytics provides detailed insight into the time elapsed between the detection of failures in a unit and its successful repair. It offers a streamlined layout along with expanded statistical controls for more granular analysis of repair processes.

Grid

The grid displays the following default columns:

• Part number
• Product name
• Test operation
• Repair operation
• Total repair time (avg)
• Failed to repair (avg)
• Repair to Passed (avg)
• Unit #

Toggle visibility for extended statistics relating to Total repair time, Failed to repair, and Repair to Passed:

• Median
• Minimum
• Maximum
• Standard Deviation

Charts

Time from First Failed UUT to First Passed UUT with Linked UUR

This column chart shows the total turnaround time from the first failed Unit Under Test (UUT) to the first passed UUT associated with a Unit Under Repair (UUR) record.

• X-axis: Time buckets
• Y-axis: Number of units in each time bucket

Time from First Failed UUT to Linked UUR

This chart highlights the lag time between identifying a failed UUT and starting a linked repair (UUR).

• X-axis: Time buckets
• Y-axis: Number of units in each time bucket

Time from Linked UUR to First Passed UUT

This view focuses on the repair execution time once the repair process has started, i.e., from the creation of a linked UUR to the first passed UUT.

• X-axis: Time buckets
• Y-axis: Number of units in each time bucket

Usage Tips

• Use the report filter panel to narrow down by date range, product lines, sites, or stations.
• Enable median, min, max, and stdev columns when you need more in-depth statistical analysis.
• Review the three charts in combination to pinpoint if delays occur before repairs start or during repairs.
• Comparisons between the first and third charts help identify whether bottlenecks are due to initiation delays or execution delays.
