Q. Illustrate Partitioning in stepwise refinement?
Problems are frequently too large and complex to be understood as a whole. Therefore we tend to partition such problems into parts that can be easily understood and establish interfaces between the parts thus that overall function can be accomplished.

1) Exposing increasing detail by moving upright in the hierarchy or
2) Functionality decomposing the problem by affecting horizontally in the hierarchy.
