Quiz on Systems Analysis and Design

What is the first phase of the Systems Development Life Cycle (SDLC)?

• Analysis

• Implementation

• Planning

• Design

Answer explanation

The first phase of the Systems Development Life Cycle (SDLC) is Planning. This phase involves defining the project scope, objectives, and resources needed, setting the foundation for subsequent phases like Analysis, Design, and Implementation.

Which of the following is NOT a characteristic of Object-Oriented Systems?

• Polymorphism

• Inheritance

• Encapsulation

• Static binding

Answer explanation

Static binding is not a characteristic of Object-Oriented Systems. The key features are polymorphism, inheritance, and encapsulation, which enable dynamic behavior and data abstraction.

What does UML stand for?

• Universal Modeling Language

• Unified Modeling Language

• Unified Method Language

• Universal Method Language

Answer explanation

UML stands for Unified Modeling Language, which is a standardized modeling language used in software engineering to visualize the design of a system. The other options are incorrect variations.

Which phase involves gathering requirements and developing a system concept?

• Analysis Phase

• Implementation Phase

• Design Phase

• Planning Phase

Answer explanation

The Analysis Phase is crucial for gathering requirements and developing a system concept, making it the correct choice. This phase focuses on understanding what the system needs to achieve before moving to design or implementation.

What is the main focus of the Elaboration phase in the Unified Process?

• Deployment

• Testing

• Analysis and design

• Programming

Answer explanation

The Elaboration phase in the Unified Process primarily focuses on analysis and design. This phase involves refining requirements and creating detailed designs, which are crucial for successful implementation.

Which methodology is characterized by iterative and incremental development?

• Waterfall Development

• Structured Development

• Agile Development

• Parallel Development

Answer explanation

Agile Development is characterized by iterative and incremental development, allowing teams to adapt to changes quickly. In contrast, Waterfall and Structured Development follow a linear approach, making Agile the correct choice.

What is the role of a Systems Analyst?

• To write programming code

• To design user interfaces

• To manage project budgets

• To understand business processes and add value

Answer explanation

The role of a Systems Analyst primarily involves understanding business processes to identify improvements and add value, rather than focusing solely on coding, design, or budget management.

Which of the following is a supporting workflow in the Unified Process?

• Requirements

• Project management

• Testing

• Design

Answer explanation

In the Unified Process, supporting workflows include activities that assist the main workflows. Project management is essential for planning and overseeing the project, making it a supporting workflow, unlike requirements, testing, and design.

What does the term 'encapsulation' refer to in Object-Oriented Systems?

• Hiding functionality

• Combining process and data

• Creating subclasses

• Defining attributes

Answer explanation

Encapsulation in Object-Oriented Systems refers to combining process and data into a single unit, allowing for data hiding and abstraction. This is essential for managing complexity and protecting the integrity of the data.

Which of the following is a characteristic of the Agile Development methodology?

• Sequential phases

• Heavy documentation

• Flexibility and adaptability

• Fixed requirements

Answer explanation

Agile Development is characterized by flexibility and adaptability, allowing teams to respond to changes and evolving requirements, unlike traditional methodologies that rely on sequential phases, heavy documentation, and fixed requirements.
