Study Notes
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.
