Building decision services

Decision services are where you create and verify your decisions. You can create an empty decision service or start from a sample decision service.

Before you begin

You need to have a decision automation where you create your decision service. For more information about decision automations, see Building decision services in Decision Designer.

About this task

A decision service contains decision artifacts that implement a decision:

Data model
The representation of business concepts in the form of data types. Use data models to describe all the data that you need to make your decisions.
Decision model
The representation of a decision. It contains a diagram that describes a decision, its subdecisions, the data that is required to make these decisions, and how they are related to each other. It includes rules and decision tables that describe the decision logic.
Generative AI model
A generative AI model is an element within an AI system designed to interpret and process prompts to generate specific outputs. This model leverages machine learning models, such as language models, to produce content that aligns with the given instructions and context.
Predictive model
The representation of a prediction based on a machine learning model. Predictions are consumed by decision models and task models.
Task model
The implementation of a decision. It contains rule artifacts and a ruleflow to organize their execution.

Procedure

  1. From your decision automation, open the Decision services tab and click New decision +.
  2. Choose whether to create an empty decision service or to create a decision service based on a sample:
    Option Procedure
    Create a decision service from scratch
    1. Click Create decision service.
    2. Enter a name for the decision service.
    3. Select a language.
    4. Add a description.
    5. Edit the group ID of the decision service.

      You need to follow a naming convention when you enter a group ID. For more information about group IDs, see Editing group IDs.

    6. Click Create.
    Import existing decision services

    You can import .zip files. These files can contain multiple decision services.

    1. Select Import decision service.
    2. Click Browse to select a file on your machine.
    3. Click Import.
    Import a sample
    A collection of samples is available in the Discovery tutorials, Industry samples, and Localized samples tabs:
    • The samples under Discovery tutorials are designed to help get you started in Decision Designer.
    • The samples under Practice tutorials are designed to help you learn best practices for modeling decisions.
    • The samples under Industry samples allow you to discover decision services tailored for specific business applications.
    • The samples under Localized samples show you an example of a simple decision service in the different languages supported by Decision Designer.

    To import a sample, select the sample that you want to import and click Import.

    Tip: You can find instructions for using the Discovery tutorials and Practice tutorials under Learning resources.

Results

Your decision service is created. You can now start working on models for the decision service.
