System Development Life Cycle (Systems development life cycle phases include planning, system analysis, system design, development, implementation, integration and testing, and operations and maintenance )
1) Inception Phase involves establishing goals and gathering the requirements needed for the software development. It involves the cost estimation and identifying the risk factors. In the inception phase, we mainly work on the scope of the project and architecture.
2) The Inception Phase is an opportunity to undertake a 'reality check' of the proposed work and to present the updated/confirmed ('adaptive' management) approach to the stakeholders of the project and to seek approval of the workplan and budget from the first Project Steering Committee.
The planning phase of the SDLC is also when the project plan is developed that identifies, prioritizes, and assigns the tasks and resources required to build the structure for a project. With that said, this step culminates in a detailed project plan .
The Software Development Plan (SDP) describes a developer's plans for conducting a software development effort. The SDP provides the acquirer insight and a tool for monitoring the processes to be followed for software development
The purpose of systems analysis is to devise a logical model of the proposed system. Using the methodology known as structured systems analysis, we graphically describe the system as interacting processes that transform input data into output data.
The analysis phase involves gathering requirements for the system. At this stage, business needs are studied with the intention of making business processes more efficient. The system analysis phase focuses on what the system will do in an effort that views all stakeholders, as viable sources of information
During the design phase, developers and technical architects start the high-level design of the software and system to be able to deliver each requirement
System design is the phase that bridges the gap between problem domain and the existing system in a manageable way. ... In this phase, the complex activity of system development is divided into several smaller sub-activities, which coordinate with each other to achieve the main objective of system development.
The systems development life cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project, from an initial feasibility study through maintenance of the completed application. SDLC can apply to technical and non-technical systems.
