What is the primary goal of system workflow design?

• To create complex systems that are difficult to manage.

• To optimize processes and ensure efficiency in achieving desired outcomes.

• To focus solely on reducing costs without considering efficiency.

• To increase the number of tasks performed in a workflow.

Name two common modeling techniques used in system design.

• Entity-Relationship Diagrams (ERD) and Unified Modeling Language (UML) diagrams

• Flowcharts and Gantt charts

• Class Diagrams and Sequence Diagrams

• Data Flow Diagrams (DFD) and Use Case Diagrams

What does a Data Flow Diagram (DFD) represent?

• A Data Flow Diagram (DFD) shows the physical layout of a system.

• A Data Flow Diagram (DFD) represents the flow of data within a system.

• A Data Flow Diagram (DFD) illustrates the organizational structure of a company.

• A Data Flow Diagram (DFD) represents the hardware components of a system.

How do use case scenarios help in system development?

• Use case scenarios are only useful for marketing strategies.

• Use case scenarios focus solely on technical specifications.

• Use case scenarios clarify user interactions and requirements, improving system design and validation.

• Use case scenarios eliminate the need for user feedback.

Describe the main components of system architecture.

• The main components of system architecture are hardware, software, network, data, users, and interfaces.

• Only hardware and software are components.

• Data is not considered a component of system architecture.

• System architecture only includes users and interfaces.

What is the purpose of process mapping in workflow design?

• To eliminate all steps in the workflow completely.

• The purpose of process mapping in workflow design is to visualize and optimize the workflow for efficiency and clarity.

• To create a detailed report of all tasks performed.

• To assign roles and responsibilities to team members.

Identify one advantage of using Data Flow Diagrams.

• They reduce the need for documentation.

• They enhance understanding of data processes.

• They eliminate the need for data analysis.

• They complicate the understanding of data processes.

What is the difference between a use case and a user story?

• A use case is more detailed and formal, while a user story is simpler and user-focused.

• A use case focuses on system requirements, while a user story focuses on business goals.

• A use case is always shorter than a user story.

• User stories are used for technical specifications, while use cases are for user interactions.

Explain the significance of actors in use case scenarios.

• Actors are crucial for identifying user interactions and requirements in use case scenarios.

• Actors are only relevant for technical specifications.

• Actors are optional and can be ignored in use case analysis.

• Actors do not influence the design of use case scenarios.

What are the key elements of a system architecture diagram?

• Components, modules, protocols, and services

• Key elements include nodes, connections, interfaces, data flow, layers, and external systems.

• Network configurations and security policies

• Hardware specifications and user manuals
