Graal Designer

Version 4.0

Graal Designer provides to analysts and agile product owners the ability to specify the users needs and their interactions with a system.

The Graal methodology allows the modeling of business systems by focusing on the user needs and his interactions with the system. By analyzing the tasks a user should be able to perform, the Graal methodology allows the analyst to define tasks, use cases, user stories and interaction aspects a system should offer.

Graal is well adapted for product owners in SCRUM methodology, as it provides specifications easily understandable by non IT users.

This module uses a dedicated Graal metamodel provided by Obeo Network community and it implements the following diagrams:

  • Tasks graph
  • Action plan
  • Use cases
  • Actors
  • User stories
  • Layers to indentify tasks related to selected user stories

This modeling tool can be used in conjunction with other designers:

  • Cinematc Designer for UI cinematic
  • SOA Designer for services
  • Entity Designer for domain model
  • Some users reports they succeeded to generate functional tests from Graal with an Acceleo generator for JBehave.

    This designer is Open Source (EPL license).
    You can easily modify it with Obeo Designer to adapt each diagram to your needs or combine it to your own DSL. To start customizing this module, just download the community edition and import the source code of Graal Designer from Github.
