Definition and Features of Prototyping
- A prototyping is an initial version of a software system.
- Demonstrate concepts.
- Try out design options.
- Find out more about the problem and possible solutions.
- Rapid, iterative development of the prototyping is essential so that costs are controlled, and system stakeholders can experiment with the prototype early in the software process.
- A software prototype can be used in a software development process to help anticipate changes that may be required:
- In the requirements engineering process, a prototype can help with the elicitation and validation of system requirements.
- In the system design process, a prototype can be used to explore particular software solutions and to support user interface design.
- A system prototype can be used while the system is being designed to carry out design experiments to check the feasibility of proposed design.
- Prototyping is also an essential part of the user interface design process.
Benefits of Prototyping
- Improve system usability.
- A closer match to users' real need.
- Improve design quality.
- Improve maintainability.
- Reduced development effort.
General Problems of Prototyping
- The prototype may not necessarily be used in the same way as the final system.
- The tester of prototype may not be typical of system users.
- The training time during prototype evaluation may be insufficient.
- If the prototype is slow, the evaluators may adjust their way of working and avoid those system features that have slow response times.
