Round 82

Maintenance Strategy for Aging Production Line

A mid-size manufacturer runs a 15-year-old production line that is central to output but increasingly prone to unplanned stoppages. Leadership must choose a maintenance strategy for the next two years. Constraints: capital budget is limited, skilled maintenance technicians are scarce in the local labor market, unplanned downtime costs roughly $40,000 per hour, and the line cannot be fully shut down for more than 72 hours at a stretch without breaching customer delivery commitments. Data quality from existing sensors is inconsistent, and OEM support contracts are available but costly. The operations team must balance upfront investment, ongoing labor needs, downtime risk, and long-term flexibility, knowing that whichever approach is chosen will shape budgeting, staffing, and vendor relationships for years to come.
