Which development approach involves creating an initial simplified version of an application for review and feedback?

The modified prototype model is a development approach that emphasizes the creation of an initial simplified version of an application, known as a prototype, which can be reviewed and tested by stakeholders. This model allows developers to gather essential feedback early in the development process, which helps in refining the requirements and improving the final product. Prototyping leads to a better understanding of the user’s needs and expectations, thereby reducing the risk of project failure due to misunderstandings or misaligned objectives.

This approach contrasts with other models. For instance, the waterfall model follows a strict sequenced structure where requirements are gathered upfront, and there is limited flexibility to make changes based on feedback until later stages. The agile model focuses on iterative development as well, but it does so through rapid iterations and continuous customer collaboration rather than through the upfront creation of prototypes. The spiral model incorporates risk assessment and iterative development but is not primarily focused on the initial simplification for immediate feedback in the same way the modified prototype model is. Thus, the modified prototype model is specifically designed to facilitate initial reviews and adjustments, making it uniquely suited for this purpose.
