From marketing and origination to customer management and collections it is now more critical than ever to provide the best quality of service to your clients. Statistical models have been proven to help organisations make decisions based on predictions across the customer life cycle. Building these models, however, can be very challenging from both a resource and project management perspective.
If companies cannot adapt their decisions promptly to take into account changes in their target market or business processes then there can be a negative financial and regulatory impact.
Getting the best data available
All standout statistical models are built on strong and relevant data so before you start to think about modelling, it is necessary to extract and verify the relevant data. This can be a difficult and lengthy process in itself, depending on how the historic data is stored and the infrastructure of the organisation. It is also worth considering if information from external sources could add benefit to the model development, or help make it more predictive.
Designing the modelling sample
Once the modelling team has acquired the data, they need to fully understand it and design a development sample. This is typically the most challenging part of the whole model development process. The analysis to determine the best sample needs to take into account several factors. The data needs to be robust, representative of the current or future target portfolio, and be as predictive as possible.
Building the model
The ideal scenario is where there is a lot of data available to build linear or logistic regression models. But it is possible to adopt alternative approaches on a case per case basis. Regardless of the modelling methodology employed, the key here is to build the most predictive, accurate models whilst ensuring that the results do not disregard business logic or objectives.
