System Development

Many failed systems were abandoned because analysts tried to build wonderful systems without understanding the organization. The primarily goal is to create value for the organization. The systems analyst is a key person analyzing the business, identifying opportunities for improvement,and designing information systems to implement these ideas. It is important to understand and develop through practice the skills needed to successfully design and implement new information systems.
Systems Development Life Cycle

• Planning (Why build the system? How should the team go about building it?)
• Analysis (Who uses system, what will it do, where and when will the system be used?)
• Design (How will the system work?)
• Implementation (System delivery)
