High level of preliminary need statement-

The higher the level, the wider is the span of concerns, but lesser is the possibility of attention to the details. An architect while designing the overall relationships among the spaces she creates has to worry about the location of windows and shutters. However, she obviously cannot be expected to consider the details of hinges and sashes to be used on the window frames. It is usually the interior designer who has to worry about these details, but if she too decides to design at the level of the inter-relationships between spaces rather than forever have an unfinished project on our hands. Somebody has to design at the lowest level of scope as well.
