no field stresses the importance of a well-built system quite like computer science. the system development life cycle is a process that involves conceptualizing, building, implementing, and improving hardware, software, or both. from banking to gaming, transportation to healthcare, the system development life cycle is applicable to any field that requires computerized systems. the importance of the requirements analysis/initiation phase cannot be overemphasized. thorough planning saves time, money and resources, and it ensures that the rest of the system development life cycle continues as smoothly as possible. the development/acquisition phase can be considered one of conceptual design and may involve: in this phase, physical design of the system takes place. elements include: this phase may also include testing and integration, or the process of ensuring that the entire system successfully works together as a single entity.
depending on the system in question, the implementation phase may take a considerable amount of time. if it is determined that the system must be completely rebuilt, the disposal phase begins. this phase represents the end of the cycle, when the system in question is no longer useful, needed or relevant. after the disposal phase, the system development life cycle begins again. the cycle usually has no conclusive end. for anyone considering a job in computer science, the system development life cycle is just one of many essential concepts required to know for a successful career. the program offers rolling enrollment, allowing students to begin their education at a time that works for them.
the documentation provides a mechanism to ensure that executive leadership, functional managers and users sign-off on the requirements and implementation of the system. such projects continue until the underlying technology ages to the point where it is no longer economical to invest in upgrades and the application is considered for either continued as-is operation or retirement. not every project will require that the phases be subsequently executed and may be tailored to accommodate the unique aspects of a projects. the initiation phase begins when management determines that it is necessary to enhance a business process through the application of information technology. if the project is to proceed, the feasibility study will produce a project plan and budget estimates for the future stages of development.
during this phase, the system is designed to satisfy the functional requirements identified in the previous phase. these include: effective completion of the previous stages is a key factor in the success of the development phase. in this phase, the system is installed to support the intended business functions. this phase continues until the system is operating in production in accordance with the defined user requirements. the system is monitored for continued performance in accordance with user requirements and needed system modifications are incorporated.
objective the objective of this phase is to ensure that there is a somewhat reasonable expectation that a reliable, effective software can be built on time the initiation of a system (or project) begins when a business need or opportunity is identified. a project manager should be appointed to the initiation phase begins when agency management determines that a business process requires enhancement through an agency information technology (it), development phase in sdlc, development phase in sdlc, planning phase in sdlc, deployment phase in sdlc, implementation phase in sdlc.
the initiation phase of the sdlc is critical to ensuring that a system is correctly planned for and developed. this phase is initiated by the decision to design and implement the system. 1.) requirements analysis/initiation phase in this first phase, problems are identified and a plan is created. elements of this phase include:. after the contract is signed, you get into the initiation phase. here you need to define what’s the goal of a project, and it’s success criteria. even if you the initiation phase is the beginning of the project. in this phase, the idea for the project is explored and elaborated. the goal of this phase is to, disposal phase in sdlc, testing phase in sdlc, maintenance phase in sdlc, 5 phases of system development life cycle, sdlc requirements phase, 7 phases of sdlc ppt, pmi initiation phase, sdlc phases in healthcare, project sdlc, system development life cycle pdf. what happens during initiation phase? what are main activities at initiation stage in sdlc model?
