Final answer:
The three characteristics of object-oriented systems analysis and design are use-case driven design for defining interactions, architecture-centric approaches for system blueprinting, and iterative and incremental development for continuous improvement.
Step-by-step explanation:
Discussing the three basic characteristics of object-oriented systems analysis and design, we focus on the methods being use-case driven, architecture-centric, and iterative and incremental development.
Use-case driven approaches use use-cases to capture functional requirements and to define the interactions between the system and its environment, often visualizing the various scenarios through which users will employ the system features.
Architecture-centric approaches involve the development of a robust system architecture early in the design process. This architecture acts as a blueprint for the system, determining how the system's elements integrate and interact.
The iterative and incremental development approach emphasizes designing and building systems through repeated cycles (iterative) and adding additional features in increments. This allows for continuous testing, refinement, and adaptation of the system as it evolves, improving quality and addressing potential issues early on.
