🎯 Risk Drivers

This screen enables you to:

1. Identify what’s driving the risk profile of a specific activity
2. Compare your Risk drivers across updates

Identify what’s driving the risk profile of a specific activity

You can quickly understand what drives the risk profile of a specific activity. From the Risk drivers tab under Schedule, select the activity, and the p-position you care about. You will immediately gain access to an interactive visualization that shows all the activities that drive the p-position with a clear breakdown of risk events and duration uncertainty for each activity.

You can limit the visualization to show only the portion of duration uncertainty or risk events using the ‘for what drivers?’ drop-down.

You can also gain access to what’s driving the P80 of specific activity from the risk screen (or any p-position). Simply select the activity you care about and click on the risk drivers button on top of the screen, you will be redirected to the Risk Drivers tab with a visual of all drivers of your P80.

Compare your Risk drivers across updates

You can quickly compare how your risk drivers are trending compared to your previous update. From the risk drivers tab, simply enable the option ‘Compare with previous update’.

Search for project wide risk drivers 

We added the option to search for project wide risk drivers. It's not always the last activity! Just click on search and search for "Project Wide" drivers.

Remove the additional drivers and the breakdown

You may want to simplify your reports and remove the "additional drivers" and the "Breakdown" options to simplify your reports simply click on those options at the right. 

Understand the Percentage Values on the Driver’s Screen

The percentages displayed on the driver’s screen represent normalized values derived from the correlation of risk drivers within N&L models. Although the initial correlation values are used to compute risk drivers, these outputs are adjusted to ensure that their total sums up to 100%.

For example, if three risk drivers have correlation values of 0.75, 0.5, and 0.75, they would be normalized to 37.5%, 25%, and 37.5%, respectively.

It's important to note that when negative risk drivers are involved, the percentages for individual risk drivers might exceed 100%. Despite this, the combined total of all risk drivers will still equal 100%. For instance, with correlation values of 0.75, 0.5, and -0.75, the normalized percentages would be 150%, 100%, and -150%, respectively.

Understand the Day Values for Risk Drivers

N&L risk drivers models use correlation methods to calculate the values for each risk driver. These correlation values are first normalized to sum up to 100%. The normalized percentages are then converted to days using the P80 delay of the target activity.

For example, consider a target activity with a P80 delay of 200 days and three risk drivers with correlation values of 0.75, 0.5, and 0.75. After normalizing these correlation values, they become 37.5%, 25%, and 37.5%, respectively. These normalized percentages are then multiplied by the P80 delay of the target activity, resulting in 75, 50, and 75 days for each risk driver.
