Analyst(s): Kurt Brenneman


Management Summary Core processing systems form the basis of the retail bank's IT platform, providing the central accounting, customer information management and transaction-processing functions. Traditionally running on IBM mainframes, these systems are offered by a select group of vendors that have long been intertwined with banking technology. There are five components to a core processing system: the deposit processing system, the loan accounting and servicing system, the general ledger system, the customer information system, and the reporting tools. This Context Overview Report provides a description of these components for core processing systems, describes the outsourcing of these products, which is one of the principle means of delivery, and discusses additional issues involved with these core systems.
