IBM Operational Decision Manager

Systems that apply business logic through rule-based engines (e.g., if-then-else structures) to automate decisions. These are often used in compliance-heavy domains and customer decision flows. In most cases rules systems make calls to data, analytics, AI, or experts in their execution.

Technologies that model systems or environments to test decisions under various scenarios. These tools help forecast outcomes, test risk scenarios, or explore decision impacts in controlled digital environments. Simulation includes vendors delivering feature driven what-if scenario analysis for particular use cases all the way to creating top down full digital twin models of a business, industry, or market.
