System Development Life Cycle (SDLC)
Information system development methodology means that a method that is used to make the development of computer-based information system. The most common method used is SDLC (System Development life Cycle) Method SDLC approach using waterfall system (Water Fall Aproach) that use some of the stages in developing system.
Stages in the development system in accordance with the SDLC includes several phases as follows:
1. Planning System (System Planning)
Early stages of development is the system that defines the requirements kebutuan-resource devices such as physical, human, methods (Engineering and operations) and the budget that are still common.
The steps:
a. Recognizing the problem
b. About the problem
c. Determining the purpose of the system
d. Identify the obstacles system
e. Make a feasibility study
f. Prepare a research proposal system
g. Approve / reject the research system
h. Setting a control mechanism
2. Stages analysis System
Is the stage of research on the existing system with the goal to design a new system / update.
Activities:
a. Identify the problem
b. Organize the project team
c. About the information needs
d. About the system performance criteria
e. Reports the analysis system
3. System Design Phase
After the analysis phase is the system that menetapakan the process of data needed and the new system.
Steps:
a. Prepare a detailed design of the system
b. Identify the various alternative systems configuration
c. Evaluate the various alternative configuration system.
d. Selecting a configuration better.
e. to do proposed implementation
f. Approve / reject the application of the system.
4. Implementation Phase
Design stage is where the system was formed into a code (program) that is ready for operation.
The steps:
a. Plan implementation
b. Conducting activities implementation
c. Setting up the physical facilities
d. Preparing personnel
e. Perform simulation
f. System new switch
5. Phase Maintenance
Is the stage after an implementation phase
The steps:
a. Use of System
b. Audit System
c. System guard
d. System Repairs
e. Improving the System
