WGU C790 - SDLC | STUDY GUIDE AND
FORMULAS | 2026 UPDATE WITH
COMPLETE SOLUTION ALREADY GRADED
A+
walking skeleton - ANSWERS-iterative development approach -
complete system structure Is built but with bare-bones functionality
later iterations flesh out/add functionality
project initiation - ANSWERS-identify problem, secure approval
project planning - ANSWERS-plan, organize and schedule
analysis - ANSWERS-discover/understand details of problem/need
design - ANSWERS-configure/structure new system
implementation - ANSWERS-programming and testing
deployment - ANSWERS-install and use
, support - ANSWERS-maintain and upgrade
predictive approach to the SDLC - ANSWERS-approach assumes
project can be planned in advance - new information system developed
according to the plan
adaptive approach to the SDLC - ANSWERS-approach assumes project
must be more flexible and adapt to changing needs as the project
progresses
waterfall model - ANSWERS-SDLC approach assumes phases can be
completed sequentially with no overlap
"no going back" - most predictive (aka not flexible)
incremental development - ANSWERS-SDLC approach completes
portions of system in small increments across iterations
each increment being integrated into the whole as it is completed
system development life cycle - ANSWERS-SDLC
conceived
design
build
