Concepts
eXvisory dev is a web-based development framework for building deep logic product support chatbots able to troubleshoot complex problems. Its main component is a visual editor based around a fault containment hierarchy.
The concepts you need to understand to use eXvisory dev are deliberately simple, to enable you to build deep logic networks without being overwhelmed by accumulating complexity.
You create and configure logic rules from a limited palette of logic rule types (faults, fault groups, eliminators, query tests and synthetic tests) and fit them together into a visual fault containment hierarchy that models how experts troubleshoot product support issues. This creates a deep logic network from which eXvisory dev automatically generates a chatbot. Inference is the route eXvisory takes through the fault containment hierarchy (and its underlying deep logic network) so that the chatbot asks the right questions in the right order with relevant help and explanations.
Most product documentation starts with a simple "Hello World" example. But eXvisory dev is about enabling you to build and maintain complex deep logic networks, so we thought we'd take a different approach and start with an easy to understand but more complex example.

As you read through the documentation keep the sample-mobile deep logic network open in another browser window or tab so you can experiment with eXvisory dev while learning by example about each of its concepts.
​Logic rules - introduces you to each of the logic rule types.
​Inference - learn how the fault containment hierarchy works and the order in which fault nodes are evaluated.
​Expressions - store test results in logic variables and logically combine test results.
​Resources - string templates used to communicate with end users.
​Variants - create alternative versions of logic rules, depending on previous test results.
​Architecture - eXvisory's cloud-based architecture.
These introductory pages are designed to give you a good idea of how eXvisory dev works and how you can use it to develop your own chatbot. See the Reference pages for the gory details.
