Credit Card Segmentation

Data Available:

  • CC GENERAL.csv

Business Context:

A Bank wants to develop a customer segmentation to define marketing strategy. The sample dataset summarizes the usage behaviour of about 9000 active credit card holders during the last 6 months. The file is at a customer level with 18 behavioural variables.

Business Requirements:

Advanced data preparation: Build an enriched customer profile by deriving “intelligent” KPIs such as:

  • Monthly average purchase and cash advance amount
  • Purchases by type (one-off, instalments)
  • Average amount per purchase and cash advance transaction,
  • Limit usage (balance to credit limit ratio),
  • Payments to minimum payments ratio etc.
  • Advanced reporting: Use the derived KPIs to gain insight on the customer profiles.
  • Identification of the relationships/ affinities between services.
  • Clustering: Apply a data reduction technique factor analysis for variable reduction technique and a clustering algorithm to reveal the behavioural segments of credit card holders
  • Identify cluster characteristics of the cluster using detailed profiling.
  • Provide the strategic insights and implementation of strategies for given set of cluster characteristics.
