$1.$ Explain the concept of object$-$oriented analysis and design $($OOAD$)$ and how it relates to the Unified Modeling Language $($UML$).$ Discuss the benefits of using UML in software development.

$2.$ Describe the stages of the software development lifecycle $($SDLC$)$ where object$-$oriented programming concepts and techniques are commonly applied. Provide examples of how object$-$oriented analysis, design, and implementation are utilized in each stage.

$3.$ Discuss the main goals of object$-$oriented analysis $($OOA$)$ and object$-$oriented design $($OOD$).$ Explain how reusability, system maintenance, and minimizing the impact of changes on other objects are achieved in object$-$oriented systems.

$4.$ Explain the concept of inheritance in object$-$oriented programming. Describe how inheritance allows for the creation of new classes from existing classes, and discuss the benefits and implications of using inheritance in software design.

$5.$ Discuss the purpose and use of CRC $($Class$,$ Responsibilities, and Collaborators$)$ cards in object$-$oriented systems analysis. Explain how CRC cards help in identifying class responsibilities and facilitating collaboration within a development team.
