Instantaneous Feedback Loop

An essential piece of a seamless authoring experience is an instantaneous feedback loop. A feedback loop on asset authoring happens when some portion of or all asset input is captured, analyzed, and used to provide insight to improve a future users’ authoring experience.

Providing such instantaneous feedback is crucial to a fluid authoring experience. But what does this mean for DMN authoring?

Automatic Form Generation

On every change of your DMN model, the DMN runner introspects it and automatically generates the input form for your DMN execution. The data that you input on it will be later used on the execution loop.

Automatic DMN evaluation

As soon as the DMN runner is connected to your session, on every change of your DMN model, we will combine your DMN model and your form input and evaluate it on the DMN Engine.

The awesome part of this workflow is that it is really fast, looking almost instantaneous. See it in action:

Automatic DMN validation

Another cool feature of DMN Runner is that together with DMN evaluation, we also validate your DMN models. Take a look at it:
