What is the Likelihood in Pega ? Why to put values from 1 to 100 ?
Likelihood : To choose which Flow action first from the different flow actions present in a flow. A likelihood is a value between 1 and 100, interpreted as an assumed or known probability associated with a flow action.
For example, a likelihood of 66 on a flow action labeled Accept means that users completing an assignment linked to that flow action are expected to choose the Accept flow action two times out of three.
Likelihood values are recorded as you edit a flow rule using Visio, and appear in the Diagram tab of a flow rule. They normally determine the order of presentation of connector flow action choices on the Perform form — highest likelihood appears first. (Alternatively, your application can display these choices in alphabetical order or other orders.)
When editing a flow rule using Process Modeler, click the icon to display likelihood values.
After the flow rule is saved and deployed, developers can compare the actual results with the likelihood factors. Click the Flow Analysis button on the Design tab of the flow rule to retrieve and summarize this data.
A likelihood is a value between 1 and 100, and it represents an assumed or known probability linked with a flow action.
Please find the great example explained in the below documentation
A likelihood is a value between 1 and 100, interpreted as an assumed or known probability associated with a flow action.
For example, a likelihood of 66 on a flow action means that users completing an assignment linked to that flow action are expected to choose the flow action two times out of three.
You can get a good example of its working in case of fork where all the output connector results are coming as true. In that case Pega will select the connector which has the highest likelihood.
Likelihood refers to the likelihood of accepting a particular action or condition, based on the values from 1 to 100 are used to represent the confidence score and likelihood score, where a higher value indicates a higher confidence or likelihood of accepting a condition.
