Identification of Unsuitable Model

1. Build & Fix Model: This model lacks a formalized structure and primarily focuses on building a system and then fixing issues as they arise. It does not accommodate changes well since there is often no defined process for integrating alterations systematically.

2. Prototyping Model: This model supports change by allowing stakeholders to see prototypes that can be iteratively modified based on feedback. It is inherently flexible, making it suitable for accommodating changes.

3. RAD (Rapid Application Development) Model: RAD emphasizes user feedback and allows for frequent iterations, thus it is also quite adaptable to changes during the development process.

4. Waterfall Model: This model follows a linear approach where each phase must be completed before the next begins. It is not designed to accommodate changes easily once the development has entered a particular phase.

Conclusion

The model that is not suitable for accommodating any change is the Build & Fix Model. It lacks a structured approach to handle modifications effectively, making it unsuitable for projects where changes may be needed.
