Notas del editor
- With digital transformation, organizations are seeking to automate more and more of their business decisions. With the complexity of these decisions continuously growing. Trisotech is delivering on the DMN promise by providing a complete Decision as a service platform.
- Digital businesses are insights driven. To turn insights into action, they rely on their ability to make the right business decisions The challenge is that complex business decisions require real-time processing of hundreds of factors, and data sources.
- Today’s dominant Decision Automation solutions are based on Business Rule Management Systems which are just a box full of rules. Current AI resurgence are driven by deep neural networks which are just a box full of nodes.
- Neither of these solutions meets current needs. Rules are continuously changing and produce decisions as side effects and current Machine Learning approaches lead to black box AI with business decisions that are unexplainable.
- A Black Box solution will not cut it. Explainable AI is required if not mandatory. Transparency, Provability and Explainability are hard requirements of business decisions. Companies must be able to explain to their customers how machine decisions are made.
- DMN: The Decision Model and Notation standard from OMG elevates Decisions as first-class citizen, provides a simple visual representation of decisions making it simple for business users, and offers a what you model is what you execute paradigm.
- Trisotech is making the DMN vision a reality with the availability of the Trisotech Decision Management Suite. The Trisotech Decision Management Suite is the first complete Decision as a Service Platform based on DMN.
- The Trisotech Decision Management Suite is composed of a DMN Modeler, a Cloud Execution Engine and a Services library that together enables the creation, packaging, testing and management of DMN based decisions Services.
- Such a platform offers forward looking digital organization with a launch pad for composite apps, knowledge distribution, microservice architecture, business automation and potential new revenue models by publicly exposing decision services for a price.
- It is a full lifecycle management platform of Decision Service APIs for composite apps. These decision services can be exposed for internal usage, for B2B purposes or can be exposed publicly to be orchestrated by various types of applications.
- Business users can create Decision Models and Decision Services using the Trisotech DMN Modeler, that can then be deployed to the Trisotech Cloud Execution engine. Deployed Decision Services can then be discovered from the Service Library and used by applications.
- Trisotech DMN modeler is a simple to use complete DMN modeling tool, supporting not only the full FEEL box expressions but also the creation of Decision Services, test cases, import and re-use and a platform wide dictionary.
- The Trisotech Cloud Execution Engine is a fast and scalable decision engine that fully supports DMN decision service execution, service documentation, service testing and service usage audits. It is an enterprise grad execution engine that can address even the most demanding situations.
- The Trisotech Service Library is a catalogue of services deployed on the Trisotech Cloud Execution Engine. It offers a user-friendly interface to select various API options of the deployed services including invocation templates and services tests.
- Decision Services can be orchestrated by external applications using a REST API. The API supports 3 input mappings: JSON, Standardized XML as per the DMN TCK and XML using best guest mapping. Two output mappings are available: JSON and XML based on DMN TCK.
- The Trisotech Decision Management Suite offers Decision Service Documentation via the OpenAPI version 2 standard. OpenAPI is vendor-neutral, portable, and open specification for providing technical metadata for REST APIs.
- Decision Service Testing is based on the DMN TCK format. There are two potential sources of test cases for Decision Service testing. Test cases serialized within the Decision Model itself and external test cases provided on the REST call.
- The Trisotech Decision Management Suite also offers a Rich HTML form for all defined Decision Services. This interface displays a form to provide the decision service inputs and displays the decision results in return. This interface also supports excel import of collections.
- Finally, the number of invocations by period by decisions can be traced from the engine. One can specify to trace the user who did the invocation, the date and time of the invocation and any error messages generated. These statistics can then be used for reporting and tend analysis purposes.
- You can now see that Trisotech is delivering on the promise of DMN decision as service. Providing a simple one click user experience, centralized dictionary, validation and testing, complete governance of both design and execution time and decision services that can be orchestrated in any applications.
