Question

discuss at least three major contributions or advantages of Object Oriented Systems Analysis and Design to design a Business System. Use one industry of your choice to discuss your views. For example, you can initiate your discussion as: "Following are advantages I find in creating a cyber-security system to protect patient data in healthcare," or "OOSAD can be used in creating a grocery’s supply-chain management system with the following advantages." These are examples. You can pick any industry or even a specific business system that you are familiar with.

Answer 1

During the software development life cycle, development is typically broken up into stages, which are loose, abstract concepts used to separate the activities taking place within each phase of development. Often, these stages might include requirements, planning, design, coding/development, testing, deployment, maintenance, and so forth.
Advantages of Object-Oriented System Analysis and Design
1* It is easy to understand.
2* It is easy to maintain. Due to its maintainability OOSAD is becoming more popular day by day
3* It provides re-usability
4* It reduce the development time & cost
5* It improves the quality of the system due to program reuse.
One important benefit of object oriented methodology which no one tells you is that: you have the ability to design using real-world terms or domain specific terms. For example, if you are working on a software related to banking services, then you can use terms like Account, Ledger, Balance Sheet within the software code (as Names or attributes of classes).
How is this beneficial? You can design the software like real systems in the real world work. This makes it easy for you to update, modify and communicate with the customers. Hence object-oriented analysis is about identifying opportunities where you can represent real-world objects in the software world. Banking system is the real world example of OOSAD.
In banking system, we have to update the data, maintain, reuse and due to several or million types of customers OOSAD helps in to save time and cost.
