Proactive retention is a strategy that anticipates potential customer churn and takes actions to

prevent it before it happens. It uses predictive analytics to identify customers who are at risk of

leaving

and

offers

them

incentives

or

solutions

to

retain

them.

The pxResult property is used to access the output of a prediction that is driven by a PMML model. It

contains the predicted value or class for each record in the input data set. Reference:

When you increase the performance threshold setting of an adaptive model rule, the number of

active predictors may decrease. The performance threshold is the minimum performance that a

predictor must have to be included in the model. If you increase this value, some predictors may not

meet

the

criteria

and

be

excluded

from

the

model.

The rank property is automatically recomputed for each decision component. It indicates the order in

which the actions are presented to the customer, based on their priority and propensity. Reference:

The Monte Carlo method is a way to create a data set that includes mock-up customer data. You can

use this method to generate random values for customer properties, such as age, gender, income,

etc.,

based

on

predefined

probabilities

and

distributions.

A prediction helps in proactive retention by predicting the customer’s churn risk. A prediction is an

estimate of the likelihood of a future outcome based on historical data and statistical models. A

prediction can help identify customers who are at risk of leaving and target them with appropriate

actions

to

retain

them.

According to the Data Scientist Student Guide1, page 18, the correct answer is B. A predictive

model and C. A control group. A predictive model is a mathematical representation of a real-world

process that can be used to predict an outcome based on input data. A control group is a subset of

customers who are not exposed to a treatment (such as an offer) and are used to measure the

effectiveness of the treatment by comparing their behavior with the treated group.

Two results of an adaptive model are propensity and performance. Propensity is the probability that

the customer will accept or respond to an offer. Performance is a measure of how well the adaptive

model

predicts

customer

behavior

over

time.

These factors indicate how accurate and explainable the models are, which are key measures of

model health. The number of responses and decisions are related more to model usage rather than

health.

The implementation of Next-Best-Action must involve defining business issue and group hierarchy,

which are used to organize and categorize propositions based on business objectives and customer

needs. Reference: https://academy.pega.com/module/one-one-customer-engagement/topic/nextbest-action-designer
