Backlog Weeks
Backlog weeks estimates how many weeks of available maintenance labor are required to complete a defined backlog.
What this term means in maintenance
Backlog weeks estimates how many weeks of available maintenance labor are required to complete a defined backlog.
Formula
Backlog weeks = Backlog estimated labor hours ÷ Available weekly maintenance labor hours
Practical example
Ready backlog contains 1,000 estimated hours and weekly available labor is 250 hours.
Backlog = 4 weeks
Which backlog to use
Organizations may calculate total backlog weeks or ready-backlog weeks. The definition should be stated.
Limitations
The measure depends on accurate estimates and realistic available labor.
Risk review
Backlog weeks should be reviewed with criticality, age, priority, and readiness.
Common mistake
Using all paid hours as available labor understates the true backlog.
How this term differs
Backlog Weeks is the labor-capacity estimate of how many weeks are needed to complete a defined backlog. It is related to Maintenance Backlog, Ready Backlog, and Backlog Prioritization, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.

Maintenance Backlog
Maintenance backlog is approved maintenance work that has not yet been completed, commonly measured by job count, estimated labor hours, age, risk, or weeks of available labor capacity.
Ready Backlog
Ready backlog is approved maintenance work that has been sufficiently planned and has the parts, labor, information, access, and safety requirements needed for scheduling.
Maintenance Capacity Planning
Maintenance capacity planning determines how much labor and skill availability exists for planned work during a future period.
