The disclosed embodiments generally relate to systems and methods for computerized decisioning, and more particularly, to systems and methods for standardized coding and deployment of attributes for financial decisioning systems coded once and deployed to multiple decisioning systems and environments. Consistent with disclosed embodiments, an attribute management system may include one or more memory devices storing instructions, and one or more hardware processors configured to execute the instructions to perform operations. Upon executing the instructions, the processors may receive a financial service request, and identify a decisioning system for processing the request. The processors may determine that an attribute is required for processing the request using the decisioning system. Then, the processors may initiate an attribute calculation service for determining an attribute value for the attribute. The processors may receive the attribute value from the attribute calculation service, and process the financial service request using the received attribute value.
