▁the ▁correct ▁balance ▁among ▁compet ing ▁high - level ▁requirements ▁in ▁the ▁functional ▁and ▁non - function al ▁analysis ▁domains . ▁ ▁System ▁analysis ▁and ▁design ▁interact s ▁strongly ▁with ▁distributed ▁enter prise ▁architecture , ▁enter prise ▁I . T . ▁Architecture , ▁and ▁business ▁architecture , ▁and ▁re lies ▁heavily ▁on ▁concepts ▁such ▁as ▁partition ing , ▁interfaces , ▁person ae ▁and ▁roles , ▁and ▁deployment / oper ational ▁model ing ▁to ▁arrive ▁at ▁a ▁high - level ▁system ▁description . ▁ ▁This ▁high ▁level ▁description ▁is ▁then ▁further ▁broken ▁down ▁into ▁the ▁components ▁and ▁modules ▁which ▁can ▁be ▁analyz ed , ▁designed , ▁and ▁constructed ▁separately ▁and ▁integrated ▁to ▁accomplish ▁the ▁business ▁goal . ▁ ▁SD LC ▁and ▁S AD ▁are ▁corner st ones ▁of ▁full ▁life ▁cycle ▁product ▁and ▁system ▁planning . ▁ ▁Object - orient ed ▁analysis ▁▁ ▁Object - orient ed ▁analysis ▁( O O A ) ▁is ▁the ▁process ▁of ▁analyz ing ▁a ▁task ▁( also ▁known ▁as ▁a ▁problem ▁domain ), ▁to ▁develop ▁a ▁concept ual ▁model ▁that ▁can ▁then ▁be ▁used ▁to ▁complete ▁the ▁task . ▁ ▁A ▁typical ▁O O A ▁model ▁would ▁describe ▁computer ▁software ▁that ▁could ▁be ▁used ▁to ▁satisfy ▁a ▁set ▁of ▁customer - defined ▁requirements . ▁ ▁During ▁the ▁analysis ▁phase ▁of ▁problem - sol ving , ▁a ▁programmer ▁might ▁consider ▁a ▁written ▁requirements ▁statement , ▁a ▁formal ▁vision ▁document , ▁or ▁inter views ▁with ▁st ake hold ers ▁or ▁other ▁interested ▁parties . ▁ ▁The ▁task ▁to ▁be ▁addressed
