Prototyping Model
Prototyping Model
A software development approach used when technical solutions are unclear. A prototype is created to explore potential issues early on.
Evolutionary Model
Evolutionary Model
A software development model where the system is built incrementally, starting with a simple working model and adding features iteratively until the desired product is complete.
Spiral Model
Spiral Model
A software development model that employs iterative loops for each phase of the project, where risk assessment guides each iteration.

Study Notes
Waterfall Model
- A sequential, linear approach to software development
- Divides development into distinct phases
- Each phase must be completed before the next can begin
Iterative Waterfall Model
- Overcomes shortcomings of the classical waterfall model
- Involves repeated cycles of the waterfall phases
- Provides feedback paths for error correction
Prototyping Model
- A prototype is a simplified implementation of a system
- Exhibits limited functionality and low reliability
- Useful for understanding user needs and clarifying technical solutions
Evolutionary Model
- Also called successive versions or incremental model
- Builds a simple working model initially
- Subsequently improves functionality incrementally
- Suitable for large projects needing incremental implementation
Spiral Model
- A risk-driven model that combines iterative development with risk analysis
- Consists of multiple iterations, each with a risk assessment phase.
- Employs prototypes to mitigate risks
- Suitable for complex projects with high risks
Requirement Analysis and Specification
- Essential for understanding customer needs before development
- System analysts gather information from the customer to understand requirements and remove ambiguities
- Includes questions like problem definition, solutions, data inputs/outputs, and possible complexities
Part of SRC Document
- Functional requirements of the system
- Non-functional requirements
- Implementation goals
Functional Requirements
- Describes the high-level functions the system performs
- Input data and output data are transformed by each function
Non-Functional Requirements
- Deals with system characteristics not expressed as functions
- Example: maintainability, portability, usability
Properties of a Good SRS Document
- Concise: Unambiguous and to the point
- Structured: Easy to understand and modify
- Black-Box View: Specifies external behavior, not internal details
- Conceptual Integrity: Clear and understandable
- Response to Undesired Events: Handles exceptional circumstances
- Verifiable: Requirements are measurable
Problems Without an SRS Document
- System may not meet customer needs
- Developers lack clarity on requirements
- Maintenance is difficult
- User manuals may be inaccurate
