Design

For us, Design means two things. The process of designing, and the aesthetic properties of de result. Well designed software should be like Design furniture, functional and good looking, both from the users point of view as from the constructors point of view.

Design vs. Architecture
Software design more or less starts where software architecture ends. That is, once the software architecture defines the overall static and dynamic structures of the system, software design is about designing how all the user needs are going to be met by the system.

Like for an apartment building, the building's archirect defines the shape and overall structure of the building. Then the interior designers design each individual apartment to meet the needs of its owners, within the overall structure defined by the architecture of the building.
