An aspect of the present disclosure generates instruction sets implementing business rules designed to update business objects of financial applications. In one embodiment, business rules designed to update business objects used by a financial application are processed to form a set of buckets (of rules) such that each bucket contains rules that do not have inter-dependency in execution order. Then, for each bucket, subsets of rules designed to update a common business object are determined, and a corresponding single instruction set is generated for each determined subset of rules. The instruction sets generated for the subsets of rules contained in each bucket are then executed concurrently.
