WGU C790 – SDLC: Questions With In-Depth
Solutions
Predictive approach to the SDLC Correct Answer - approach
assumes project can be planned in advance - new information
system developed according to the plan
Adaptive approach to the SDLC Correct Answer - approach
assumes project must be more flexible and adapt to changing needs
as the project progresses
Waterfall model Correct Answer - SDLC approach assumes
phases can be completed sequentially with no overlap
"no going back" - most predictive (aka not flexible)
Incremental development Correct Answer - SDLC approach
completes portions of system in small increments across iterations
Each increment being integrated into the whole as it is completed
Walking skeleton Correct Answer - iterative development
approach - complete system structure Is built but with bare-bones
functionality
Later iterations flesh out/add functionality
Project initiation Correct Answer - identify problem, secure
approval
Project planning Correct Answer - plan, organize and schedule
