Solution

The correct option is A informal design review

The preliminary evaluation of top-down design before programs are written is referred to as an informal design review.

Top-down and bottom-up are both strategies of information processing and knowledge ordering, used in a variety of fields including software, humanistic and scientific theories, and management and organization. They can be seen as a style of thinking, teaching, or leadership.

A top-down approach is essentially the breaking down of a system to gain insight into its compositional sub-systems in a reverse engineering fashion. In a top-down approach an overview of the system is formulated, specifying, but not detailing, any first-level subsystems.

Informal design review are a useful mechanism whereby the design of a product can be optimised through a systematic review of and feedback on design process outputs. Typically a number of formal and informal reviews are conducted during the duration of a design project.
