In systems engineering, information systems engineering, engineering, and software engineering, the systems development life cycle, also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system.

4. Introduction

The software development lifecycle (SDLC)
is the cost-effective and time-efficient process
that development teams use to design and
build high-quality software.
The goal of SDLC is to minimize project risks
through forward planning so that software
meets customer expectations during
production and beyond.

8. V Model

Fig 3: V Model
The V-model is a type of SDLC
model where the process executes in a
sequential manner in a V-shape. It is
also known as the Verification and
Validation model.
It is based on the association of a
testing phase for each corresponding
development stage.

The Iterative Waterfall Model is a software development approach
that combines the sequential steps of the traditional Waterfall
Model with the flexibility of iterative design.

10. Spiral Model

Fig 5: Spiral Model
The Spiral Model is a SDLC model that provides a systematic and
iterative approach to software development. In its diagrammatic
representation, looks like a spiral with many loops.

11. Agile Model

Fig 6: Agile Model
Agile SDLC model is a combination of iterative and
incremental process models with focus on process adaptability
and customer satisfaction by rapid delivery of working software
product.

12. Discussion

Fig 6: Agile Model
After finishing this SDLC a presentation, we now know the steps
involved in creating a software product. Every industry must
maintain the SDLC process in order to create a product that meets
all requirements, including correct timing, money, and
specifications. If not, you won't be able to accomplish your precise
goal in the right amount of time and manner.
Our teacher of the course did her best to help us in understanding
this material, which might be helpful to the legal profession as well.
It is difficult for the attorney to determine the victim's right
outcome if there is no correct systematic method in place.
