Questions and Answers

What is the significance of the System Development Life Cycle (SDLC) in systems analysis?

The SDLC provides a structured approach to developing systems, ensuring each phase of the project is addressed systematically.

How do use case-driven development and Agile techniques contribute to capturing functional requirements?

They focus on real-world user interactions to identify functional requirements and adapt to changes quickly.

Describe the role of a systems analyst in project management.

A systems analyst assesses user requirements, designs solutions, and ensures effective communication between stakeholders and developers.

What are Entity-Relationship Diagrams (ERDs) and their role in domain modeling?

ERDs represent data relationships and entities, helping to visualize and structure the database schema for the system. Signup and view all the answers

Explain the importance of user interface (UI) design in systems development.

UI design impacts user experience (UX) by ensuring the system is intuitive and accessible, increasing user satisfaction and efficiency. Signup and view all the answers

What distinguishes Agile methodology from traditional approaches to systems development?

Agile emphasizes flexibility, iterative progress, and continuous feedback, while traditional approaches follow a more linear, sequential process. Signup and view all the answers

Study Notes

Part 2: Systems Analysis Activities

Investigating System Requirements involves understanding stakeholder needs and workflows. Key activities include identifying stakeholders and their roles, using information-gathering techniques (interviews, questionnaires, observations), and creating workflow models (Activity Diagrams). Requirements are categorized as functional (what the system does) and nonfunctional (performance, constraints). Models are essential for documentation.
Identifying User Stories and Use Cases focuses on capturing functional requirements using Agile or traditional methods. User stories (brief descriptions of user needs, e.g., "As a user, I want to access my account so I can see my balance") and use cases (detailed interactions between users and systems) are crucial for capturing functional requirements. Techniques include the User Goal and Event Decomposition techniques. Use case diagrams visually represent relationships between actors and functionalities.
Domain Modeling aims at defining the problem domain's objects and relationships. Key tools are Entity-Relationship Diagrams (ERDs) for data relationships, Domain Model Class Diagrams for objects and their attributes, and State Machine Diagrams for object behavior. The process involves identifying entities, defining relationships, and modeling states and transitions.
Use Case Modeling details use case interactions. Components include use case descriptions (steps and exceptions), activity diagrams (workflows), and systems sequence diagrams (inputs/outputs). CRUD (Create, Read, Update, Delete) techniques ensure all actions are considered.
Traditional Approaches (Online Chapter B) explores traditional methods like Data Flow Diagrams (DFDs) for mapping data flow within a system. This section compares traditional with object-oriented approaches.

Part 4: System Development and Project Management

Approaches to System Development (Chapter 10) covers various methodologies:
- System Development Life Cycle (SDLC): A structured approach (planning, analysis, design, implementation, maintenance).
- Agile: Iterative development, collaboration, flexibility.
- Unified Process (UP): Iterations with clear milestones and deliverables.
- Extreme Programming (XP) and Scrum: Incremental delivery, adaptive planning.
Project Planning and Management (Chapter 11) highlights project management principles in systems development:
- Problem Identification: Defining project goals, objectives, and scope.
- Planning and Monitoring: Developing schedules, allocating resources, tracking progress using tools like Gantt charts.
- Key Tools: PERT/CPM Charts (visualizing task dependencies and timelines), financial metrics like Net Present Value (NPV) and Return on Investment (ROI).
Project Management Techniques (Online Chapter C) covers advanced project techniques, possibly using Microsoft Project, and standards based on the Project Management Body of Knowledge (PMBOK) from the Project Management Institute.
