Answer Posted / indudhar devanath
While analyzing and designing a system, we take into
consideration the flexibility, scalability, performance,
maintainability and testability. When these capabilities
are not taken into consideration, we see a high probability
for system failure. Conversely, if too much of analysis and
design goes into building a system, we see similar symptoms
of failure. Considerable skill and practice goes into
building successful systems. It is worth to note that only
20% or less of the software projects ever succeed.
