How many crew-weeks is your maintenance backlog?

Quick answer

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. Nothing leaves your browser.

hrs

Estimated labour hours in all outstanding (incomplete) work orders.

hrs/wk

Crew size x productive hours available for backlog work each week.

How it is calculatedBacklog (crew-weeks) = total outstanding work hours / available maintenance hours per 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.

Frequently asked questions

What backlog level should I aim for?
Around 4 to 6 crew-weeks of ready, planned work. Less and crews wait between jobs; much more, or growing, and you are deferring work that returns as failures.
