A. B. C. D.A.
Prototype systems can provide significant time and cost savings, however they also have several disadvantages.
They often have poor internal controls, change control becomes much more complicated and it often leads to functions or extras being added to the system that were not originally intended.

Prototyping is the process of creating a preliminary model or sample of a product, system, or software to test and refine its functionality and design. Prototyping can have several advantages, including:
A. Prototype systems can provide significant time and cost savings: Prototyping can help identify potential issues and areas of improvement early in the development process, reducing the overall development time and cost. By creating a preliminary model or sample, the development team can test and refine the system's functionality and design before investing significant time and resources into building the final product.
B. Change control is often less complicated with prototype systems: Since prototypes are typically less complex than the final product, changes to the prototype are usually easier to make and test. This can reduce the risk of introducing errors or bugs into the system when changes are made. In addition, prototyping can help identify potential areas of change and allow for testing and refinement before the final product is developed.
C. It ensures that functions or extras are not added to the intended system: Prototyping can help ensure that the final product includes only the required functionality and features. By testing and refining the prototype, the development team can identify potential areas of unnecessary complexity and eliminate them before investing time and resources into building the final product.
D. Strong internal controls are easier to implement: Prototyping can help identify potential risks and vulnerabilities in the system and allow for the implementation of strong internal controls before the final product is developed. By testing and refining the prototype, the development team can identify potential security and compliance issues and address them before the system is deployed.
In summary, prototyping can provide significant advantages in terms of time and cost savings, easier change control, ensuring the intended functionality, and implementing strong internal controls.
