Analisis Kebutuhan Sistem (Fungsional dan Non Fungsional) | Analisa dan Desain Sistem

Summary

In this video, Vida Mastika explains the concept of system requirements in the context of system analysis and design. She breaks down the two main categories of system needs: functional and non-functional requirements. Functional requirements focus on the features and capabilities the system must provide, such as user tasks and system operations. Non-functional requirements, on the other hand, define the system's quality attributes, including user experience, security, and response time. Vida also highlights the importance of both types of requirements for creating efficient and user-friendly systems, and teases the next video on how to collect system requirements.

Takeaways

• 😀 System analysis and design often focuses on defining and understanding system requirements, particularly functional and non-functional needs.
• 😀 Functional requirements describe what a system must do, such as what features and actions it should support for its users.
• 😀 Non-functional requirements describe the quality attributes of the system, focusing on user experience, such as performance, security, and usability.
• 😀 Business requirements set high-level goals like improving income, reducing costs, or enhancing customer service, which guide system development.
• 😀 User requirements capture the needs of different stakeholders, such as managers, staff, and customers, each having distinct interests and roles in the system.
• 😀 Product requirements outline the operational features and functions that the system needs to meet the business and user requirements.
• 😀 Functional requirements should be clear, simple, and unambiguous, focusing on actions, inputs, and outputs for specific tasks within the system.
• 😀 Non-functional requirements focus on system performance, such as response time, accessibility, and the technology used to enhance user experience.
• 😀 A well-defined functional requirement ensures the system can perform the necessary tasks, like inputting and modifying data in an academic system.
• 😀 Non-functional requirements emphasize the system's usability and how efficiently and securely it operates, like response times and device compatibility.
• 😀 Both functional and non-functional requirements are crucial for system development, with functional requirements focusing on capabilities and non-functional requirements focusing on quality attributes.

Q & A

What are the two main types of system requirements discussed in the video?

The two main types of system requirements discussed are functional requirements and non-functional requirements.

How do functional requirements differ from non-functional requirements?

Functional requirements describe what the system should do, i.e., the system features and capabilities. Non-functional requirements describe how the system should perform, focusing on user experience, security, and system performance.

What are some examples of functional requirements in a system?

Examples of functional requirements include tasks like inputting student data, searching for student records, changing data, and processing grades in an academic system.

Why is it important for functional requirements to be clear, simple, and unambiguous?

Clear, simple, and unambiguous functional requirements ensure that everyone involved in the system development process understands what the system is supposed to do, preventing confusion and errors.

What role does user experience play in non-functional requirements?

User experience is a key focus in non-functional requirements. A system’s usability, such as its response time and how it performs across different devices, significantly impacts user satisfaction.

What are some key factors that fall under non-functional requirements?

Key factors under non-functional requirements include system response time, security (who can access what data), technology compatibility (access on different devices), and the overall system performance.

Can a system be successful without meeting non-functional requirements?

No, even if a system meets all functional requirements, poor non-functional performance, such as slow response times or poor user interface design, can make the system frustrating to use and ultimately unsuccessful.

What is the importance of having well-defined business and user requirements?

Well-defined business and user requirements are essential for ensuring that the system meets the goals of the organization and satisfies the specific needs of various stakeholders, such as managers, employees, and customers.

Why is security considered a non-functional requirement?

Security is a non-functional requirement because it pertains to the quality and safety of the system. It ensures that data is protected and that access is restricted based on user roles, enhancing overall trust in the system.

How does the video define the term 'non-functional requirements' in simple terms?

Non-functional requirements are described as the general nature or quality of the system, focusing on aspects like user experience, system security, and technological compatibility, which improve overall system comfort and satisfaction.
