TLDRThis video discusses the reasons behind the need for new system development, which may include leveraging new technologies, solving existing system issues, or adopting new business methodologies. It outlines the System Development Life Cycle (SDLC) phases: planning, analysis, design, implementation, testing, and maintenance, emphasizing the significance of each. The presenter highlights the importance of the requirement phase, noting its critical role in gathering user needs, which are essential for successful system integration and satisfaction. The video also explains the waterfall model approach in system development, alongside feasibility studies (operational, technical, and economic) which are necessary to evaluate a system's viability. The requirement phase is identified as the most crucial, as it engages users to communicate their needs, ensuring the system's alignment with their expectations through various channels, such as interviews and social media.

Pertanyaan yang Sering Diajukan
Why is new system development necessary?
New system development is necessary to take advantage of new technologies, solve problems with existing systems, or adopt new business approaches.
What are the phases of the System Development Life Cycle (SDLC)?
The phases include planning, analysis, design, implementation, testing, and maintenance. It often follows a waterfall approach.
Which phase of the SDLC is considered the most important?
The requirement phase is considered the most important because it determines what users need from the system, ensuring its acceptance and success.
What are the types of feasibility studies in system development?
The types of feasibility studies include operational feasibility, technical feasibility, and economic feasibility.
What is operational feasibility?
Operational feasibility examines whether a new system can be effectively integrated into the organization’s current operations, considering available hardware and software.
How is the requirement phase conducted?
The requirement phase involves understanding user needs, often through interviews, questionnaires, or social media engagement.
Why is user input crucial in the requirement phase?
User input is crucial because the system must meet user needs and expectations, or it risks being quickly retired as unsuccessful.
What methods can be used to gather user requirements?
Methods include interviews, questionnaires, and leveraging social media platforms like Facebook, WhatsApp, WeChat, or Viber.
