Case study

Mirion’s Detector line reached 100% on-time delivery

Mirion improved Detector delivery from 50% in 2021 to 100% achieved, with performance separately reported as stabilized and maintained above 90%. AMT and Mirion addressed supplier timing, rework and cross-training through distinct operating changes.

At Mirion Technologies (IST) Corporation, Detector on-time delivery to major customers was 50% in 2021. MI Cable subassembly production was identified as the main source of delay.

The documented result

50%

Detector on-time delivery in 2021.

100%

Detector on-time delivery achieved.

Above 90%

On-time delivery maintained, reported separately.

What the investigation found

AMT conducted high-level process mapping with a cross-functional Mirion team around MI Cable subassembly production. The work identified late suppliers, elevated rework, and insufficient cross-training in critical operations. Additional cross-functional teams then took on the distinct sources of delay.

What changed

Supplier lead times were adjusted for post-COVID conditions. Teams investigated major rework causes and created training programs to increase coverage of critical operations.

Three conditions, three operating responses
  • SupplyExpected lead times match operating conditions.
  • ReworkTeams investigate the major causes.
  • Critical skillsTraining increases task coverage.

How the change became part of the work

The training programs aimed to increase the number of people able to perform critical operations, alongside the separate supplier-timing and rework workstreams. AMT and Mirion established morning meetings in critical shop-floor areas to sustain the changes and gather employees’ improvement ideas.

The routine connected continuing observation to the teams responsible for supplier timing, rework and skill coverage. Its value was keeping those distinct corrections in the work and bringing new improvement ideas forward. The published account does not isolate the contribution of any one workstream to the delivery result.

How the result was measured

Detector on-time delivery reached 100%. The account separately reports on-time delivery stabilized and maintained above 90%.

The percentage is the reported Detector on-time-delivery score with major customers, beginning at 50% in 2021 and reaching 100%. The account does not define whether it counts orders, lines, units, or shipments, or which promised date is used. The separate above-90% sustainment figure has no stated observation window; it does not establish permanent 100% delivery or a result across all Mirion operations.

The operating decision

One delivery result can combine conditions requiring different responses. Supplier timing, repeated work, and skill coverage call for different operating changes. The sustaining meeting has a purpose: keep those changes working and bring emerging problems into view.

Which supplier, quality or skill conditions are converging on the same late job—and who owns each response?
