ICICI Bank : Posidex Dedupe

The credit card issuance process involves evaluating credit worthiness of the

applicant based on a number of market driven parameters and standardized

processes. For this, the credit decisioning system (NACS) interfaces with

various systems and external agencies as part of the decision making process.

Hence a need was felt to allow for a more robust, flexible and dynamic system

which will be parameterized, with no vendor involvement. Integration of NACS

with Posidex for positive dedupe functionality and Blaze Rule Engine (BRE) for

scoring allowed for a dedupe to be much tighter and scoring to be parameterized

and in user control thereby allowing for better control and TAT. Dedupe is an

application matching logic used to catch the applications of the same applicant

who had applied earlier for a credit card.

In this project, the dedupe and Blaze Rule Engine (BRE) databases are hosted

on different servers with GUI options to allow for rapid changes in parameters

to keep up with market dynamics and changes in policy decisions. In the old

dedupe setup, 90% of the applications were having an average of 1-2 matches per

application, while with Posidex, 85% of the applications are having about 1-10

matches per application.

This has resulted in an average dedupe percentage of 47% with Posidex as

against the 21% with the older logic. The total estimated savings will be Rs 225

million PA assuming a 5% increase in approval and decline rates under the

Posidex dedupe match logic and Rs 450 million PA with an assumption of 10%

increase in approval and decline rates. All this has led to an almost 10 times

improvement in processing speeds with minimal hardware requirements.
