The principles outlined in the 1999 book "The Unified Software Development Process" emphasize that modern object-oriented approaches to software development must be use-case driven, architecture-centric, and iterative and incremental. These properties are fundamental because they promote clarity, flexibility, and focus on core requirements throughout the development process. Understanding each of these properties is crucial for implementing effective and adaptive software development strategies.

First, being use-case driven means that development primarily revolves around identifying, analyzing, and fulfilling specific user scenarios or use cases. This approach ensures that the system's design aligns closely with user needs and that requirements are clearly understood and validated early in the development cycle. Use-case modeling helps in capturing functional requirements, facilitating communication among stakeholders, and guiding the design process.

Second, an architecture-centric process emphasizes designing a robust, adaptable architectural framework early in development. The architecture serves as a blueprint guiding subsequent development activities and ensuring that system components work together harmoniously. It promotes high-level planning, manageability, and reuse. By focusing on architecture, teams can better handle complexity, ensure system quality attributes (such as performance and security), and adapt to changing requirements with minimal disruption.

Third, an iterative and incremental approach involves developing the system through repeated cycles (iterations), each producing a functional subset of the final product (increments). This methodology allows early detection of issues, continuous feedback from stakeholders, and progressive refinement of features. It provides flexibility to adapt to evolving requirements and reduces risk by delivering manageable portions of the system over time.

The three models produced by an architecture-centric process are the use-case view, design view, and process view. These models describe different perspectives of the system to facilitate understanding among various stakeholders and to guide different aspects of development.

The use-case view focuses on capturing system requirements from the user's perspective. It models user interactions with the system, illustrating what the system should do. This view is instrumental in communication with end-users and stakeholders, ensuring the software aligns with business needs. It is primarily represented through use-case diagrams in UML, showing actors and their interactions with the system.

The design view provides a detailed blueprint of the system's structure, focusing on how the system is decomposed into classes, components, and subsystems. It describes the static architecture, including class diagrams, component diagrams, and deployment diagrams. This view helps developers understand the organization of system components, their relationships, and data flow, ensuring the system is modular, scalable, and maintainable.

Finally, the process view emphasizes the system's runtime behavior, handling concurrency, communication, and synchronization among components. It includes sequence diagrams, activity diagrams, and state machines, illustrating how system components collaborate during execution. This view is vital for performance tuning, concurrency management, and understanding runtime interactions, especially in distributed and multi-threaded environments.

In conclusion, the properties of being use-case driven, architecture-centric, and iterative and incremental foster agile, flexible, and requirement-focused software development practices. The three models—use-case, design, and process views—offer comprehensive perspectives to guide development from understanding user needs to designing the system structure and managing runtime behaviors. Mastery of these concepts enhances the ability to deliver high-quality software that meets user expectations and adapts to changing technological landscapes.
