MIS SYSTEM DEVELOPMENT LIFE CYCLE

MIS System Development life Cycle

System Development Life Cycle (SDLC), also known as application development life-cycle, is a term used in systems engineering, information systems, and software engineering, a process for the planning, construction, testing, and development of information systems Describes The System Development Life Cycle Concept applies to a range of hardware and software configurations,


MIS SYSTEM DEVELOPMENT LIFE CYCLE

as the system is made up of a combination of both hardware and software. This cycle usually consists of six stages: analysis, design, development and testing, implementation, documentation, and evaluation.

Planning


This is the first phase of the system development process. It identifies whether a new system is needed to achieve business objectives. It is a preliminary plan for the acquisition of resources to build on infrastructure for the company's business initiatives.


The company can try to meet the expectations of its employees, customers. The purpose of this step is to find out the scope of the problem and determine the solution. Resources, cost, time, profit, and other items should be considered at this stage.


Systems Analysis and Requirements


The second phase is where businesses work on the source of their problem or the need for change. In the event of a problem, possible solutions are presented and analyzed to identify the most appropriate for the end goal of the project. Where the team considers the functional requirements of the project or solution.


Where system analysis occurs — or by analyzing the needs of end-users — is to ensure that the new system can meet their expectations. System analysis is important in determining what the requirements of a business are, as well as how they can be met.


Systems Design


The third step is for end-users to discuss and determine their specific business information for the proposed system. It is during this phase that they will consider the components (hardware and/or software) structure (networking capabilities), processing, and processes for the system to meet their objectives.


Development


The fourth stage is when the actual work begins - specifically, when a programmer, network engineer, and/or database developer is brought in to do major work on the project. This task involves using flow charts to ensure that the process of the system is properly organized.


The development phase marks the end of the initial segment of the process. Additionally, this phase marks the beginning of production. The stage of development is also characterized by excitement and change. Focusing on training during this phase can be of enormous benefit.


Integration and Testing


The fifth phase involves system integration and system testing, in which it is specifically checked for errors, bugs, and differences. This test will be done until the end-user finds it acceptable. Another part of this phase is verification, which helps both ensure the successful completion of the program.


Implementation


The sixth step is when most of the code for the program is written. Additionally, this phase includes the actual installation of the newly-developed system. This phase puts the project into production by transferring data and components from the old system and placing them directly into the new system via a cutter.


7. Operations and Maintenance The seventh and final phase includes maintenance and regularly required updates. This is done when end users can fix the system, add new capabilities or meet additional user requirements to boost performance if they wish.
