is to identify the information technology needs of a business that is cost effective while also meeting the company's current and future needs. The Systems Development Life Cycle begins by identifying the businesses' needs and is broken down into these seven stages: planning, system analysis, system design, development, testing, implementation, and maintenance. The following is a brief description of each phase.
Planning Phase
Once the need for an updated or new system has been identified, the planning stage begins; a systems analyst will create a plan, budget, and schedule for a new system, which management will overview, analyzing the system to determine if it is a good fit for the organization technically, economically, operationally, and whether the schedule is realistic. Once this is done, management will decide whether changes are needed or the system can be built as recommended.
Systems Analysis Phase
System analysis follows the planning stage, because this is when the analyst reviews the plan, studies the organization, and observes business operations in order to have a precise understanding of any existing problems to identify solutions and issue recommendations. Once a clear understanding of the organizations needs are established the system can be designed.
Design Phase
The system design phase is where the new system is detailed: what parts, functions, hardware, and software it should contain. After the system has been designed, the design is unchangeable to prevent going over budget or behind schedule.
Development Phase
Once the system has been designed, the building process or the development phase can begin; the system has to meet the specifications set in the design phase.
