It should provide standardbehavior through standard abstractions and mechanisms. Thus, a key aspect indesigning a software architecture is the definition and the selection of themechanisms that designers use to give "life" to their objects.In Architectural Analysis, it is important to identify the analysis mechanisms for thesoftware system being developed. Analysis mechanisms focus on and address thenonfunctional requirements of the system (that is, the need for persistence, reliability,and performance), and builds support for such non-functional requirements directlyinto the architecture.Analysis mechanisms are used during analysis to reduce the complexity of analysis,and to improve its consistency by providing designers with a shorthand representationfor complex behavior. Mechanisms allow the analysis effort to focus on translating thefunctional requirements into software abstractions without becoming bogged down inthe specification of relatively complex behavior that is needed to support thefunctionality but which is not central to it.5 - 19
