What is the purpose of a prototype in system development?
- To immediately provide a full working solution to the end user
- To help the end user understand the layout and operations of the new system (correct)
- To finalize the system without any scope for improvement

Study Notes
Purpose of Prototyping
- The primary purpose of a prototype in system development is to validate assumptions and test hypotheses about the system's functionality and usability.
Evolutionary Approach
- The main characteristic of the Evolutionary approach to prototyping is that it involves a series of iterative refinements, where the initial prototype is continuously refined and improved until it reaches the desired level of functionality and quality.
Throwaway Approach
- The Throwaway approach to prototyping is distinguished by its focus on quickly building a prototype to test a specific idea or concept, with the intention of discarding it once the testing is complete, and then building a new prototype from scratch.
Benefits of Prototyping
- Prototyping provides stakeholders with a tangible representation of the solution, allowing them to visualize and interact with the system before it's fully developed.
- Prototyping enables early detection and correction of errors, reducing the risk of costly rework later in the development process.
- Prototyping offers a platform for testing and refining the system's functionality, usability, and performance, leading to a more robust and effective solution.
