4. INTRODUCTION
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.

Requirement Analysis
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.

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.

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.

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.
