An improved method and system for developing a reinsurance administration system. Developers may build application programs for reinsurance administration with increased re-use of existing functionality and decreased development time. A business process framework may include common functionality for a plurality of business processes and a template for executing steps in the business processes. The common functionality may include behavior for GUI elements such as windows and buttons, error logging, and database commit and rollback transactions. One or more business process subclasses may be derived from abstract business process classes in the business process framework. One or more support processes in the business process framework may be specified for a business process. The support processes may include support processes for data or syntax validation, GUI, persistent data storage, security, and/or precondition checks. One or more hook methods in the business process framework may be overridden by a business process to identify methods to be performed at various points during execution of the business process. The business processes may be combined to build one or more application programs.
