System design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. The process involves a deep understanding of the system's functional and non-functional requirements, constraints, and trade-offs. The goal of system design is to create a robust, scalable, and maintainable solution that meets the needs of its users.

• To ensure requirements are met: System design ensures that the system being developed meets all the specified requirements, including functionality, performance, reliability, and security.

• To create a scalable and maintainable system: A well-designed system is one that can be scaled easily to handle future growth and is maintainable, meaning it can be updated, repaired, and enhanced with minimal effort.

• To reduce development costs: A good system design can help to reduce the overall development costs by ensuring that the system is developed efficiently and with a minimal number of defects.

• To minimize risks: System design helps to identify and mitigate risks early in the development process, reducing the likelihood of costly errors or delays.

• Understanding of business requirements: System designers should have a deep understanding of the business requirements and objectives for the system being developed. This includes the functional requirements, as well as any non-functional requirements such as performance, reliability, and security.

• Technical expertise: System designers should have a solid understanding of the technologies being used to develop the system. This includes knowledge of programming languages, frameworks, libraries, and other tools and technologies.

• Understanding of software architecture and design patterns: System designers should be familiar with software architecture and design patterns that can be used to create scalable and maintainable systems.

• Communication skills: System designers should have excellent communication skills to ensure that all stakeholders are on the same page and that everyone understands the design decisions being made.
