Answer / katti
Top down methodology is one where overall picture of the
system is defined first. Then we go into the details of the
sub-systems in the next level and so on. So to brief this,
first the complex system is seen as a whole and then this
is broken down to smaller simpler pieces.
Top down approach is preferred when understanding of the
complete system is done. Sufficient knowledge of the system
is required.

Answer / mansi
In a top down approach an overview of the system is first
formulated, specifying but not dealing any first level
subsystem, Each subsystem is then refined in yet greater
detail, sometimes in many additional subsystem levels, until
the entire specification is reduced to base elements.

Answer / mansi
Separating the low level work from the higher level objects
leads to a modular design.
Modular design means development can be self contained.
Having skeleton code illustrates clearly how low level
module integrate.
No functionality will exist until development of low level
objects is complete
