Why Dynamic Testing?
Why ? How ? When? What? What's the purpose?
Benefits of the tests?
When do I do the test?
How do I do the tests?
What's wrong with the routing well proven test
ethodology?
Is it faster! "etter and eaningful?

Why Dynamic Testing?
#ewer Prote$tion s$hees are ore %ople&
Powerful
More fle&i"le
More $ustoia"le
(iffi$ult to test with the siple routing tests
(ynai$ testing provides
Meaning full testing %ustoied tests to $he$) the whole s$hee or
