Software Development Life Cycle Models fully solved 2023SDLC Model - correct answer A framework that describes the activities performed at each stage of a software development project Waterfall model - correct answer Requirements, design, implementation Requirements - correct answer defines needed information, function, behavior, performance and interfaces. Design - correct answer data structures, software architecture, interface representations, algorithmic details Implementation - correct answer source code, database, user documentation, testing Waterfall strengths - correct answer -Easy to understand, -Provides structure to inexperienced staff -Milestones are well understood - Sets requirements stability - Good for management control -quality is more important Waterfall Deficiencies - correct answer -requirements must be known upfront -inhibits flexibility -false impression of progress -does not reflect problem-solving nature -integration at end -little opportunity for customer to preview system When to use Waterfall model - correct answer -Requirements are very well known - Product definition is stable - Technology is understood - New version of an existing product - Porting an existing product to a new platform. V-shaped SDLC Model - correct answer variant of waterfall that emphasizes verification and validation -Testing of product is planned in parallel V-shaped Weaknesses - correct answer Does not -handle concurrent events -dynamic changes in requirements -risk analysis when to use V-shaped model - correct answer -systems requiring high reliability -all requirements are known up-front solution and tech are known Structured Evolutionary prototyping model - correct answer -developers build a prototype
