Discusses the concept of refining a design using a blueprint-like approach. ... In a nutshell, the concept of "stepwise refinement" is to take an object and move it from a general perspective to a precise level of detail. Architects have used such an approach for years, as have engineers building products.

A top-down approach is essentially breaking down a system to gain insight into its compositional sub-systems. In a top-down approach an overview of the system is first formulated, specifying but not...

step-wise refinement A technique of writing software where you gradually add error checking and functionality. Usually you take the intermediate results to show the end user to see if experimenting with that prototype changes his mind at all about the overall program specifications.

PRINCIPLES OF STEPWISE REFINEMENT ; In order to verify complex systems against their requirements one needs intermediate levels of abstraction. This can be achieved best by deriving a system formally by stepwise refinement.

A guideline in the process of stepwise refinement should be the principle to decompose decisions as much as possible, to untangle aspects which are only seemingly interdependent, and to defer those decisions which concern details of representation as long as possible.

As for stepwise refinement and top-down design, let us first comment that despite the fact that we will here advocate a top-down design method, sometimes in real world problems a bottom-up approach is needed.
