![]() This, however, carries many risks, including complex system maintenance, human resources, and high cost. The complete credit risk decision process can be fully customized and proprietary to a financial institution. This can significantly shorten a change management cycle and improve the decision-making process. Any performance degradation of existing predictive models is captured using the model monitoring capability that, in turn, provides automated feedback into machine learning models, enabling real-time self-correction. For improved decision-making, advanced business processes may incorporate adaptive analytic techniques by using model monitoring capabilities and machine learning algorithms. Model management and monitoring are also important components of an EDM system. Return on investment (ROI) analysis – measuring the impact of business decisions – can also be the part of the business process, informing the optimal decision strategy. In addition, many optimization levels can be added in the process flow considering different objective functions such as minimizing operational cost or maximizing the margin. Many predictive models can be utilized within a business process flow assessing various risk elements, such as fraud, delinquency, default and churn, or calculating applicants’ affordability and lifetime value. Overriding decisions are based on specific company rules and exclusion criteria. Overrides can either approve applications that the score cutoff would’ve otherwise rejected, or reject applicants who would’ve been scored above the score cutoff. Overrides are a form of business decision that can overrule decisions based on a credit score cutoff value. A mix of business rules and advanced analytics is typically considered when creating a decision requirements diagram for credit risk (Figure 1).īusiness rules can be extensive encompassing internal and external policies, regulations, and best practices typical examples of business rules include age requirements, employment status, credit history, bankruptcy and write-off history, different fraud rules, in-house records on exiting products, and more. Decisions are consumed within a business process flow and can be reused in other processes. Heterogeneity with diversity of data sources, synchronous and asynchronous processes, both local and remoteīusiness decisions are the key outputs of an EDM system.Transparency (so technical and non-technical professionals can understand, share, assess and audit business processes).Scalability, (the capacity to handle a growing amount of processes that are both easy to change and extend).A decision management system is only valuable if it can fulfill the following: With its three fundamental components: data, logic, and interface, an EDM system provides the framework for translating data into actionable decisions using data-, model-, knowledge-, communication-, and document-driven decision-making processes. Making the full EDM picture requires bringing additional pieces together, including customer application processing, internal and external data gathering, policy rules, additional analytical models for fraud detection and risk management, optimization, overrides, and more. However, this is still insufficient for executing the complete credit-risk decision process. By putting these pieces together, we can start building a bigger picture of the enterprise decision management (EDM) system.
