How many crew-weeks is your maintenance backlog?
This free calculator converts your outstanding maintenance work into crew-weeks, the standard way to size a backlog, by dividing total outstanding work hours by available maintenance hours per week. A healthy ready backlog is around 4 to 6 crew-weeks.
Backlog is easiest to judge in crew-weeks rather than raw hours or job counts. Enter your outstanding work and weekly capacity to see where you sit against the healthy 4 to 6 week range. The calculation runs entirely in your browser. If it is useful, you can choose to email yourself the result.
Estimated labour hours in all outstanding (incomplete) work orders.
Crew size x productive hours available for backlog work each week.
A rough sizing. Healthy ready backlog is about 4 to 6 crew-weeks. Much more, or a figure that keeps growing, signals deferred work accumulating as future failures.
