    2. 2. Confidential and Proprietary2• Encompasses processes to improve, streamline andautomate operational decision making within organizations.• Use all available organizational resources to increaseprecision, consistency and agility of decisions.• Treat decisions as reusable assets and leverage technologyat key decision points to automate the process.• Uses tools such asPredictive AnalyticsBusiness IntelligenceBusiness RulesAdaptive ControlArtificial IntelligenceDECISION MANAGEMENT

    7. 7. Confidential and Proprietary7• Clients - internal cloud or external cloud?• Self service – all components need to be provisioned on a self service basis. Provideflexibility to cherry pick from various available components.• Multi-tenancy – for internal cloud, each team/domain can be a tenant within thecloud decision management infrastructure. Each tenant is isolated and gets all theservices in the cloud based decisioning infrastructure.• Web based rules & models management – Web based interface to managepolicies that lead up to the decision as well perform verification & validation.• Managed APIs – Provide REST APIs to interact with both design time aspects(repository, rule definitions, data models etc.) and run time (execute rules, ruleanalytics etc.).• Simulations – Invoke decisions against a sample set of input data to determineimpact and optimize decisions.• Data Mining – Capture decisions for adaptive controls or correctionsDECISION ENGINE IN THE CLOUD -CONSIDERATIONS

    10. 10. Confidential and Proprietary10• Each tenant should be configurable by adding parts• Built with parts− A database part (for user, preferences, rules, simulation data etc.)− A simulation application part for running simulations on eligible decision services− A rules maintenance part for managing decisions and creating new.• Group parts into patterns− A pattern for design time authoring. Some patterns may omit parts (for e.g.simulation not required all the time)− Another pattern for executing decisions (runtime).• Group patterns into virtual systems deployed in virtual environments− The design time data pattern and app pattern assembled together to form a virtualsystem for decision maintenance.INDIVIDUAL TENANT ORGANIZATION
