Imran Khan is presenting on Kiviat diagrams & Goal Structuring Notation. Kiviat diagrams, also known as radar charts, are a graphical method to display multivariate data using axes representing quantitative variables. Goal Structuring Notation is a graphical argumentation notation used to explicitly represent safety arguments by showing requirements, claims, evidence and their relationships. It has been adopted in safety-critical industries like aerospace and defense to present safety justifications and arguments.

2. 1. Kiviat Diagrams

3. Kiviat Diagrams
A (Kiviat Diagrams) or radar chart is
a Graphical method of
displaying multivariate data in the form
of a two-dimensional Chart of three or
more quantitative variables
represented on axes starting from the
same point. The relative position and
angle of the axes is typically
uninformative.

12. Kiviat Diagrams (Application)
I.
II.
One application of radar charts is the
control of Quality Improvement to
display the performance metrics of
any ongoing program.
They are also being used in sports to
chart players' strengths and
weaknesses, where they are usually
called spider charts.

13. Kiviat Diagrams (Limitations)
I.
radar charts have been criticized as
poorly suited for making trade-off
decisions
II.
t is hard to visually compare lengths of
different spokes

14. 2. Goal Structuring Notation

15. Goal Structuring Notation
The Goal Structuring Notation (GSN) is
a
graphical argumentation notation –
explicitly
represents the individual elements of
any
safety
argument
(requirements, claims,
evidence and context)
and (perhaps more significantly) the
relationships that
exist between these elements.

16. Goal Structuring Notation (Example)

17. Goal Structuring Notation
(Principal Elements Of GSN)

18. Goal Structuring Notation
In Europe, GSN has been adopted by
a
growing number of companies within
safety critical industries (such as
aerospace, railways and defence) for
the presentation of safety arguments
within safety cases.

19. Application of Goal Structuring Notation
The following list includes some of the
applications of GSN to date:
