Westpac bank has approximately 80 applications to manage their core product functions and 100 more applications to provide additional capabilities. A core product application supports only a small number of products such as bank accounts, credit cards, investments etc. Delivery mechanism of the core product is tightly coupled in the core product application, thus resulting into a product silos.
