What is the Software Development Lifecycle (SDLC)?

The Software Development Lifecycle (SDLC) is a step-by-step process used to create software. It guides developers from the first idea to the finished product and maintenance, ensuring quality and efficiency.

Name the common phases of the Software Development Lifecycle.

The common phases are:<br>1. Planning<br>2. Analysis<br>3. Design<br>4. Implementation (Coding)<br>5. Testing<br>6. Deployment<br>7. Maintenance

beginner

Why is the Testing phase important in SDLC?

Testing finds and fixes errors before the software is used by people. It ensures the software works as expected and is safe to use, like checking a car before driving it.

What happens during the Maintenance phase of SDLC?

Maintenance means fixing problems and updating the software after it is released. It keeps the software working well and adds new features if needed, like servicing a machine regularly.

beginner

How does the Planning phase help in software development?

Planning sets goals and decides what the software should do. It helps avoid confusion later, like making a map before a trip.

Which phase of SDLC involves writing the actual code?

A Testing

B Design

C Implementation

D Planning

Implementation is the phase where developers write the software code.

What is the main goal of the Testing phase?

A To fix bugs and ensure software works correctly

B To plan the project timeline

C To design the user interface

D To deploy the software to users

Testing finds bugs and checks that the software works as expected.

During which phase do developers decide what features the software should have?

A Analysis

B Maintenance

C Deployment

D Implementation

Analysis is when requirements and features are decided.

What is the purpose of the Deployment phase?

A To write the software code

B To release the software for users to use

C To test the software

D To plan the project

Deployment means making the software available to users.

Which phase comes after Deployment in the SDLC?

A Planning

B Testing

C Design

D Maintenance

Maintenance follows Deployment to keep software updated and fix issues.

Explain the main phases of the Software Development Lifecycle and what happens in each phase.

Think of SDLC as a journey from idea to finished software and beyond.

Why is following a Software Development Lifecycle important for creating software?

Consider how a plan helps in building a house or completing a project.
