Need these two discussion questions answered by Noon on Saturday, 15 Nov 2014. No length requirement. One paragraph per question will be great. Content must be original Select an organization that you are familiar with and determine the most advantageous benefits of using object-oriented design in this organization and state why. In addition, explain the places within this organization that object-oriented design is not advantageous.

Evaluate the use of polymorphism in the object-oriented design of a project. Provide an example of a clear use of polymorphism and an example of an inefficient use of polymorphism.

Object-oriented design (OOD) offers numerous advantages for organizations by promoting modularity, reusability, and maintainability of software systems. For example, a retail chain organization can benefit significantly from utilizing OOD principles by modeling products, customers, and transactions as distinct objects. This approach allows for streamlined management of inventory, customer profiles, and sales processes, making it easier to update or expand functionalities without affecting the entire system. Additionally, encapsulation and inheritance facilitate code reuse and reduce redundancy, leading to more efficient development cycles. However, OOD may not be advantageous in organizations where the problem domain is inherently procedural or linear, such as simple data entry or batch processing systems, where the overhead of object management outweighs the benefits. In these cases, procedural programming approaches can be more straightforward and performant, avoiding unnecessary complexity introduced by object hierarchies.

Polymorphism in object-oriented design enables objects of different classes to be treated as instances of a common superclass, with method calls resolved at runtime. A clear example of polymorphism is in a graphics application where a base class Shape has subclasses like Circle, Square, and Triangle. Each subclass implements a draw() method, allowing the main program to invoke shape.draw() without knowing the specific shape type, thereby simplifying code extension and maintenance. Conversely, an inefficient use of polymorphism might occur when excessive layers of abstraction are introduced without clear benefit, such as creating numerous subclasses for minor variations that could be handled more efficiently through simple parameterization or conditional logic. Over-application of polymorphism can lead to increased complexity, reduced clarity, and performance degradation, especially if the dynamic dispatch mechanisms are overused in performance-critical parts of the application.
