▁a ▁job , ▁problem ▁or ▁assignment . ▁ ▁Task s ▁in ▁project ▁management ▁are ▁activity ▁that ▁needs ▁to ▁be ▁accomplished ▁within ▁a ▁defined ▁period ▁of ▁time . ▁ ▁Task ▁analysis ▁is ▁the ▁analysis ▁or ▁a ▁break down ▁of ▁exactly ▁how ▁a ▁task ▁is ▁accomplished , ▁such ▁as ▁what ▁sub - tasks ▁are ▁required ▁ ▁Time ▁limit ▁is ▁a ▁narrow ▁field ▁of ▁time , ▁or ▁a ▁particular ▁point ▁in ▁time , ▁by ▁which ▁an ▁objective ▁or ▁task ▁must ▁be ▁accomplished . ▁ ▁Tim eline ▁is ▁a ▁graph ical ▁representation ▁of ▁a ▁chron ological ▁sequence ▁of ▁events , ▁also ▁referred ▁to ▁as ▁a ▁chron ology . ▁It ▁can ▁also ▁mean ▁a ▁schedule ▁of ▁activities , ▁such ▁as ▁a ▁tim et able . ▁ ▁U ▁▁▁ ▁Un ified ▁Process : ▁The ▁Un ified ▁process ▁is ▁a ▁popular ▁iter ative ▁and ▁increment al ▁software ▁development ▁process ▁framework . ▁ ▁The ▁best - known ▁and ▁extens ively ▁documented ▁ref in ement ▁of ▁the ▁Un ified ▁Process ▁is ▁the ▁R ational ▁Un ified ▁Process ▁( R UP ). ▁ ▁V ▁▁ ▁Value ▁engineering ▁( VE ) ▁is ▁a ▁system atic ▁method ▁to ▁improve ▁the ▁" value " ▁of ▁goods ▁and ▁services ▁by ▁using ▁an ▁exam ination ▁of ▁function . ▁ ▁Value , ▁as ▁defined , ▁is ▁the ▁ratio ▁of ▁function ▁to ▁cost . ▁ ▁Value ▁can ▁therefore ▁be ▁increased ▁by ▁either ▁impro ving ▁the ▁function ▁or ▁reducing ▁the ▁cost . ▁ ▁It ▁is ▁a ▁primary ▁ten et ▁of ▁value ▁engineering ▁that ▁basic ▁functions ▁be ▁preserved ▁and ▁not ▁be ▁reduced
