By default your prioritization settings are based on an equal or weighted scoring approach (learn more about our focus score).

However, advanced users may want to customize the prioritization formulas for your **factors** as well as your **focus score** (the number in the blue bubble).

The **factor formulas** define the factors scores and how your items get plotted on the 2x2 priority chart.

Per factor formula (e.g. "Y") you can only use the corresponding criteria variables (e.g. "Y1" or "Y2").

To change the equations, you can use numbers, mathematical operators, and variables (e.g. Y, Y1, Y1_MAX, ...). Supported mathematical operations are: +, -, *, /, ^, sqrt, log, abs, min, max.

Intercom's famous RICE prioritization framework is a great custom formula example. Let's look at how you can utilize the custom formulas to calculate a normal as well as a normalized RICE version.

**RICE**: Using this focus score formula ("Y1 * Y1_MAX * (Y2 * 0.75 + 0.25) * Y3 / max(1e-12,X)") you will get values that go beyond 100.**Normalized RICE**: Using this formula min((Y1 * Y2 * Y3 / max(1e-12,X) * 100),100), your focus scores will get normalized to a range between 0 and 100 (like in the airfocus default).

Of course you can also manage your factors (X, Y, R) as well as their underlying criteria the same way you do that in the other scoring modes. Add new criteria (e.g. Y1, Y2, ...) or change the details of existing factors and criteria by clicking their names.**Have questions?** Please get in touch via chat. We reply usually within minutes.
