▁( dom ains ), ▁and ▁relate ▁to ▁the ▁SD LC ▁phases ▁as ▁shown ▁in ▁the ▁figure . ▁ ▁To ▁manage ▁and ▁control ▁any ▁SD LC ▁initi ative , ▁each ▁project ▁will ▁be ▁required ▁to ▁establish ▁some ▁degree ▁of ▁a ▁work ▁break down ▁structure ▁( W BS ) ▁to ▁capture ▁and ▁schedule ▁the ▁work ▁necessary ▁to ▁complete ▁the ▁project . ▁The ▁W BS ▁and ▁all ▁program m atic ▁material ▁should ▁be ▁kept ▁in ▁the ▁" project ▁description " ▁section ▁of ▁the ▁project ▁not ebook . ▁The ▁W BS ▁format ▁is ▁mostly ▁left ▁to ▁the ▁project ▁manager ▁to ▁establish ▁in ▁a ▁way ▁that ▁best ▁describes ▁the ▁project ▁work . ▁ ▁There ▁are ▁some ▁key ▁areas ▁that ▁must ▁be ▁defined ▁in ▁the ▁W BS ▁as ▁part ▁of ▁the ▁SD LC ▁policy . ▁The ▁following ▁diagram ▁describes ▁three ▁key ▁areas ▁that ▁will ▁be ▁addressed ▁in ▁the ▁W BS ▁in ▁a ▁manner ▁established ▁by ▁the ▁project ▁manager . ▁The ▁diagram ▁shows ▁coverage ▁sp ans ▁numerous ▁phases ▁of ▁the ▁SD LC ▁but ▁the ▁associated ▁M CD ▁has ▁a ▁subset ▁of ▁primary ▁ma ppings ▁to ▁the ▁SD LC ▁phases . ▁For ▁example , ▁Analysis ▁and ▁Design ▁is ▁primarily ▁performed ▁as ▁part ▁of ▁the ▁Ac quisition ▁and ▁Im plementation ▁Domain ▁and ▁System ▁Build ▁and ▁Pro totype ▁is ▁primarily ▁performed ▁as ▁part ▁of ▁delivery ▁and ▁support . ▁ ▁Work ▁break down ▁struct ured ▁organization ▁▁ ▁The ▁upper ▁section ▁of ▁the ▁work ▁break down ▁structure ▁( W BS ) ▁should ▁identify ▁the ▁major ▁phases ▁and ▁mil est ones ▁of ▁the ▁project ▁in ▁a
