!!! Overview [{$pagename}]s are generally limitations imposed on an a specific [Architecture]. [{$pagename}]s, most commonly referred to as Design constraints, [{$applicationname}] feels these are more accurately referred to as [Architecture] [{$pagename}]s. There are two common perspectives on the process of architectural [design]. __The first__ is that a designer starts with nothing--a blank slate, whiteboard, or drawing board--and builds-up an [architecture] from familiar [design] components until it satisfies the needs of the intended system. __The second__ is that a designer starts with the system needs as a whole, without [{$pagename}]s, and then incrementally identifies and applies [{$pagename}]s to elements of the system in order to differentiate the [Architecture] and allow the forces that influence system behavior to flow naturally, in harmony with the system. ([null style]) Where the first emphasizes creativity and unbounded vision, the second emphasizes restraint and understanding of the system [context]. [{$pagename}]s are classified into: * [Functional Requirements] - such as specifications of features ** [User Experience] - to applicable laws, regulations and standards. * [Non-functional requirements] - Requirements that specify intangible elements of an [Architecture]. For example, a non-functional requirement that a building be accessible. ** [Regulatory compliance] - ** [Commercial Constraints] - such as time and budget !!
