powerful development software that has evolved recently.”

Question 10

Why RAD?

Answer 10

Traditional development lifecycles, are too slow and
rigid to meet the business demands of today’s
economy
A new methodology must be implemented, one
that allows organizations to build software
applications faster, better, and cheaper.
RAD enables such development.
