Software Life Cycle Models

A software life cycle model (also called a process model) is a visual representation of the software development process.
It outlines all the steps involved in creating a software product from its initial conception to its retirement.
Different models may order the development activities differently, but all include basic development activities.
Using a life cycle model ensures a structured and disciplined approach to software development, facilitating collaboration and project management.

The Need for A Software Life Cycle Model

Without a software life cycle model, the development process can become chaotic and disorganized.
A life cycle model serves as a roadmap for the team, defining the order of development tasks and ensuring each phase is completed before moving on.
This model defines entry and exit criteria for each development phase, allowing for consistent progress and efficient project monitoring.

Different Software Life Cycle Models

Many life cycle models exist each with advantages and disadvantages:
- Classical Waterfall Model
- Iterative Waterfall Model
- Prototyping Model
- Evolutionary Model
- Spiral Model

Classical Waterfall Model

The classical waterfall model is a linear, sequential approach to software development.
It divides the development process into distinct phases:
- Feasibility study: Determines the feasibility of the project by assessing financial and technical feasibility.
- Requirements analysis and specification: Documents the functional and non-functional requirements of the software.
- Design: Defines the architecture, modules, and interfaces of the system.
- Coding and implementation: Translates the design into code.
- Testing: Identifies errors and ensures the software meets the specified requirements.
- Deployment and maintenance: Releases the software and manages its performance after launch.
