The Safety Case Diagram is enriched
with pre-render checks. These checks are based on certain standard and rules.
All the rules necessary for a GSN diagram are implemented in these diagrams,
thus providing a great ease to user. Now there is no need to check all the
standard rules manually. All this would be done automatically, when the
user would select to draw the Safety Case Diagram.
The new implemented rules to draw GSN diagram and their short description
are given below.
- Root must be a Goal.
According to this rule, the root object
of the Safety Case Module must be a Goal.

Module to draw a GSN diagram.
