SDLC Quiz

Define SDLC.

Answer explanation

SDLC stands for Software Development Life Cycle. It is a structured process that outlines the stages of software development, including planning, design, implementation, testing, deployment, and maintenance.

What is the purpose of SDLC?

Answer explanation

The purpose of SDLC (Software Development Life Cycle) is to provide a structured approach for developing software, ensuring quality, efficiency, and meeting user requirements through defined phases like planning, design, implementation, and maintenance.

List all the phases in SDLC in order.

Answer explanation

The phases in the Software Development Life Cycle (SDLC) are: 1) Planning, 2) Analysis, 3) Design, 4) Implementation, 5) Testing, 6) Deployment, and 7) Maintenance. This order ensures a structured approach to software development.

What is the importance of planning & requirement analysis phase?

Answer explanation

The planning and requirement analysis phase is crucial as it defines project scope, identifies stakeholder needs, and sets clear objectives, ensuring that the development process aligns with user expectations and reduces risks.

What is the importance of design phase?

Answer explanation

The design phase is crucial as it establishes the blueprint for the project, ensuring that all requirements are met and guiding the development process. It helps in identifying potential issues early, saving time and resources.

Differentiate functional and non-functional requirements.

Answer explanation

Functional requirements specify what a system should do (features), while non-functional requirements define how a system performs tasks (usability, reliability). Both are essential for comprehensive system design.

What are black box and white box testing?

Answer explanation

Black box testing evaluates software functionality without knowledge of internal code, focusing on inputs and outputs. White box testing involves examining the internal logic and structure of the code, ensuring all paths are tested.

List the 4 types of testing discussed in this chapter.

Answer explanation

The four types of testing discussed in this chapter are unit testing, integration testing, system testing, and acceptance testing. Each type serves a specific purpose in the software development lifecycle.

What are the popular SDLC models in industry now?

Answer explanation

Popular SDLC models include Agile, Waterfall, DevOps, and Spiral. Agile emphasizes iterative development, while Waterfall follows a linear approach. DevOps integrates development and operations for faster delivery, and Spiral combines iterative and risk-driven elements.

What is waterfall model?

Answer explanation

The waterfall model is a linear and sequential approach to software development. It consists of distinct phases: requirements, design, implementation, testing, deployment, and maintenance, where each phase must be completed before the next begins.
