Kebutuhan Fungsional dan Non Fungsional

Summary

This video explains the importance of understanding software requirements, focusing on the distinction between functional and non-functional requirements. It offers practical insights for software engineers, showing how functional requirements define system features and operations, while non-functional requirements ensure performance, reliability, security, and usability. Using an online learning system as an example, the video highlights real-world applications, including user registration, data security, and system responsiveness. The video aims to help viewers comprehend the process of managing requirements, from identifying problems to validating specifications, ensuring successful software development.

Takeaways

• 😀 The video introduces the concept of software engineering, specifically focusing on the importance of software requirements.
• 😀 Software requirements are divided into two main categories: user requirements and system requirements.
• 😀 User requirements describe what services the system should provide to users, while system requirements define the operational and functional needs of the software.
• 😀 Functional requirements focus on the core processes or services that the system must deliver, such as data management or user interactions.
• 😀 Non-functional requirements emphasize system behaviors like performance, security, and usability, which support the functionality but aren't directly involved in the main operations.
• 😀 The process of determining requirements involves several steps: identifying problems, defining business objectives, creating scenarios, negotiating specifications, and validating them.
• 😀 In software engineering, both functional and non-functional requirements are critical for designing a system that meets the needs of its users and operates efficiently.
• 😀 Functional requirements should be specific and detailed, describing what the system will do and how it will interact with users.
• 😀 Non-functional requirements set limits on how the system should operate, such as ensuring compatibility across different devices or guaranteeing secure data handling.
• 😀 The script includes an example of a learning management system, demonstrating how both functional and non-functional requirements are defined for such a system.
• 😀 The video concludes by encouraging viewers to apply the principles of defining functional and non-functional requirements when developing software applications.

Q & A

What is the purpose of software requirements engineering?

Software requirements engineering focuses on defining what a software system should do and how it should behave. It involves gathering and analyzing both functional and non-functional requirements to ensure the system meets user and business needs.

What are the two main categories of software requirements?

The two main categories of software requirements are user requirements and system requirements. User requirements outline what the users expect, while system requirements define the software's functionality and behavior.

What is the first step in the requirements engineering process?

The first step in the requirements engineering process is problem identification. This involves understanding the challenges the software is meant to solve and the needs of the users.

What is the purpose of the negotiation step in requirements engineering?

The negotiation step ensures that all stakeholders, including users, developers, and managers, agree on the software's functionalities and design. This helps resolve conflicts and align the expectations of everyone involved.

How are functional requirements different from non-functional requirements?

Functional requirements describe the specific behaviors or functions of the software, such as registration features or payment processing. Non-functional requirements define how the software should perform, such as security, reliability, and usability.

Can you provide an example of a functional requirement for an online learning system?

An example of a functional requirement for an online learning system could be the ability for students to register for courses and instructors to track attendance.

What are non-functional requirements, and why are they important?

Non-functional requirements specify how a system should behave, such as its performance, security, and compatibility with different devices or platforms. They are important because they ensure the system is reliable, efficient, and meets the user's expectations beyond just functionality.

What is the significance of the validation step in the requirements engineering process?

The validation step ensures that the requirements accurately reflect the users' needs and that the system being developed will meet those needs. This step is crucial to avoid building a product that does not satisfy the intended goals.

How does requirements management play a role in the software development process?

Requirements management involves tracking changes to the requirements throughout the development cycle. This ensures that all stakeholders are aligned, and any changes are properly documented and addressed to avoid scope creep.

What are some common examples of non-functional requirements for an online learning system?

Some common non-functional requirements for an online learning system might include ensuring the system's compatibility with multiple browsers, maintaining data security, and providing a user-friendly interface that is easy to navigate for both students and instructors.
