Software Development Life Cycle Quiz

The purpose of SDLC is to design, develop, and test high-quality software that meets or exceeds customer expectations, and to ensure that the software reaches completion within time and cost estimates. It is a process used to produce high-quality software for a software project within an organization.

1. Classical Waterfall Model: This model follows a linear and sequential approach to software development, with each phase dependent on the deliverables of the previous phase.
2. Iterative Model: This model involves repeating the development phases, allowing for feedback and refinement throughout the process.
3. Incremental Model: In this model, the software is developed and delivered in increments, with each increment adding new functionality.
4. Agile Model: This model emphasizes flexibility and customer collaboration, with a focus on iterative and incremental development.

OPJU stands for OP Jindal University, which is located in Punjipathra, Raigarh, India.

The key objectives of SDLC are to produce high-quality software, meet or exceed customer expectations, and ensure the completion of the software within time and cost estimates.

SDLC consists of a detailed plan describing how to develop, maintain, replace, and alter software within a software organization.

The Classical Waterfall Model for Software Development is characterized by a linear and sequential approach, where each phase must be completed before the next one begins. The phases include requirements gathering and analysis, system design, implementation, testing, deployment, and maintenance. This model is rigid and does not accommodate changes well once a phase is completed.

The iterative model for software development involves the repetitive refinement of the software through multiple iterations or cycles. Each iteration includes phases similar to the waterfall model, but with the flexibility to revisit and revise previous stages. Advantages of this model include the ability to accommodate changes, early detection of defects, and the generation of working software early in the project timeline.

The incremental model for software development follows the principles of dividing the software into small, manageable modules or increments, with each increment delivering a portion of the functionality. It emphasizes the delivery of a fully functional part of the system in each increment, allowing for incremental development and testing.

The Agile Model for Software Development is characterized by its iterative and flexible nature, allowing for adaptive planning, evolutionary development, early delivery, and continuous improvement. In contrast, the Classical Waterfall Model follows a linear and sequential approach, with a focus on completing each phase before moving to the next. The Agile Model also prioritizes customer collaboration and responds well to changes, while the Classical Waterfall Model is less adaptable to change once a phase is completed.

The main objective of the SDLC is to produce high-quality software that meets or exceeds customer expectations, reaches completion within time and cost estimates, and follows a structured process for development, maintenance, replacement, and alteration within a software organization.
