Kiviat diagrams & Goal Structuring Notation

1. Kiviat Diagrams

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.

Kiviat Diagrams

Other Names:

I. Web chart

II. Spider chart

III. Star chart

IV. Star plot

V. Cobweb chart

VI. Irregular polygon

VII. Polar chart

Kiviat Diagrams (Radar Chart

Types)

Kiviat Diagrams (Application)

I. One application of radar charts is the

control of Quality Improvement to

display the performance metrics of

any ongoing program.

II. They are also being used in sports to

chart players' strengths and

weaknesses, where they are usually

called spider charts.

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

2. Goal Structuring Notation

Goal Structuring Notation

The Goal Structuring Notation (GSN) isa

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.

Goal Structuring Notation (Example)


(Principal Elements Of GSN)


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.

Application of Goal Structuring Notation

The following list includes some of the

applications of GSN to date:
