How risk scores are calculated

In the work order insights report, each work order is assigned a risk score, which is a number between 0-1000 that represents how risky the work order is relative to other similar work orders.

The way this number is calculated differs depending on whether the work order is already delayed.

Delayed work orders

If a work order is already delayed, it is automatically assigned a score between 850-1000. The longer the work order has been delayed past its suggested completion date, the higher its risk score.

The other factors described in the section below are not taken into account for delayed work orders.

All other work orders

If a work order isn’t delayed (because either it doesn't have a suggested completion date, or the date is still in the future), its risk score is based on how much work it represents and how likely it is to be delayed.

We calculate the amount of work in a work order using the following data:

  • Estimated time

  • Time spent (i.e. logged hours)

  • Number of assets

  • Number of parts

  • Number of tasks

  • Number of task changes

  • Number of technicians assigned

The work order is assigned an initial score for its workload  based on how much it differs from other work orders for the same asset, maintenance type, and priority.

Next, for work orders with a suggested completion date, our algorithm calculates how likely the work order is to be delayed. If the algorithm identifies a risk of delay, the work order is assigned an additional score that represents this risk (where a higher score equals a higher risk of delay). This score is then added to the initial score that was assigned based its workload.

For work orders without a risk of delay (or without a suggested completion date), we use the initial score that was based solely on its workload.


We have 4 example work orders:

  • Work Order 1 is still open past its suggested completion date. As a result, it is automatically assigned a risk score between 850 and 1000 (the longer the delay, the higher the risk score).

  • Work Order 2 is not predicted to be delayed, so its risk score is based solely on how much its workload differs from other work orders with the same asset, priority, and maintenance type.

  • Work Order 3 has a similar workload to other work orders, but is predicted to be delayed. As a result, its risk score will be based mostly on its risk of delay.

  • Work Order 4 is predicted to be delayed, and has a very different workload compared to other work orders. Its risk score is the sum of both its workload anomalies and its risk of delay. As a result, this work order will have a very high risk score.
