WGU C179 SDLC Questions and Answers
with Complete Solutions 100% Correct | 2025
Update
systems development life cycle (SDLC) - ANSWER a highly structured, phased
approach to implementing a new information system
SDLC is divided into the following five phases: - ANSWER 1) planning or Define
System
2) analysis or Determine Requirements
3) design
4) implementation
5) maintenance
Two structures used to help manage the SDLC - ANSWER work breakdown
structure and
Gantt chart.
The work breakdown structure - ANSWER An outline view of the tasks to be
completed, which are organized by phases. This document provides a scope and
schedule of the major systems development tasks in systemic order.
Gantt chart - ANSWER Project management software used to manage the
project from a higher-level perspective. Displays tasks and dependencies in a
matrix view.
, If any task changes, updating the task produces an updated chart.
SDLC Strengths - ANSWER •Ability to monitor and maintain control over large
projects
•Detailed phases that guide systems development in a controlled manner
•Good documentation
•Great user input into requirements
•Easy systems maintenance
•Ability to make changes to the information technology staff without affecting the
development process
(in theory!)
SDLC Weaknesses - ANSWER •Longer development time than other
methodologies
•Increased development costs
•Need for well-defined systems at outset, before development starts
•Rigid process
•Some difficulty in estimating scheduling and budgeting
•Limited user input
SDLC Phase 1: Planning - 3 major tasks - ANSWER 1) Define the scope of the
system
2) Conduct Feasibility Studies
3) Form a Project Team
