Software Development Life Cycle By Team Orange (Dept. of Pharmacy)

Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality software. The SDLC aims to produce a high-quality software that meets customer expectations, reaches completion within times and cost estimates.

7. Waterfall Model The Waterfall Model was the first Process Model to be introduced. It is also referred to as a  linear-sequential life cycle model . It is very simple to understand and use. In a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. Fig 2: Waterfall Model 4/19/2024 7

8. V Model Requirement Design System Design Architecture Design Module Design Acceptance Test System Test Integration Test Unit Test Coding The V-model is a style of software development that splits the process into three parts: design, implementation, and integration qualification testing. The letter V is a symbolic representation of the development flow. Fig 3: V Model 4/19/2024 8

9. Iterative Model In this Model, you can start with some of the software specifications and develop the first version of the software. After the first version if there is a need to change the software, then a new version of the software is created with a new iteration.

10. Spiral Model The spiral model combines the idea of iterative development with the systematic, controlled aspects of the waterfall model. This Spiral model is a combination of iterative development process model and sequential linear development model i.e. the waterfall model with a very high emphasis on risk analysis.

11. Agile Model The Agile Model was primarily designed to help a project adapt quickly to change requests. So, the main aim of the Agile model is to facilitate quick project completion. To accomplish this task, agility is required. Fig 6: Agile Model 4/19/2024 11

12. Discussion Just as the SDLC provides a systematic approach to developing software, legal professionals also rely on structured processes to ensure the correct outcome for their clients. Without such a method in place, it can be challenging for attorneys to navigate complex legal matters and determine the appropriate course of action to secure justice for their clients. By applying the principles of systematic methods like the SDLC to other industries, such as law, professionals can enhance efficiency, accuracy, and ultimately achieve better outcomes for their stakeholders. It's great that your teacher helped you draw parallels between software development and other fields, highlighting the universality of structured approaches in achieving success. 4/19/2024 12
