Software Development Life Cycle (also called SDLC) is a workflow process which defines the core stages and activities of development cycles or A framework that describes the activities performed at each stage of a software development project. Show
Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high-quality software’s. The SDLC aims to produce high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. System analysts can use it, designers and developers to plan and implement the applications and deliver the systems or products on time and within budget. With numerous development methodologies, it is never an easy task to choose an appropriate strategy that sometimes even it is inevitable to mix-and-match multiple methods to fit in a single project. SDLC Phases are as follows The following figure shows the details process of Software Development Life Cycle, Project Initiation This is the first stage in the Software Development Life Cycle where the project is initiated. Business Analyst Training Other components that are to be considered in this stage are Resources, time/schedules, milestones, cost, business benefits and deadlines. In the case of enhancements to existing projects, the strengths and weaknesses of the current software are studied, and the improvements are set as a goal, along with the collected requirements. Extensibility: Requirements Gathering Business requirements are gathered. Analysis The Analysis Phase is where you break down the deliverables in the high-level Project Charter into the more detailed business requirements. The Analysis Phase is also the part of the project where you identify the overall direction that the project will take through the creation of the project strategy documents. • Understand the business need and processing needs System Design • This is
the stage which stated, “How to achieve what is needed?” Development • Taking all
the detailed design documents from the design phase and transforming them into the actual system. Testing • This stage
is the one where the quality check takes place. The developed software is assessed to ensure that all the specified requirements are met. Deployment or Implementation • Write detailed user documentation and provide training for the system user. Maintenance • This stage
is when the “fine tuning” of the software takes place. Once the build is deployed to Production environment, any issues that the real users face are considered as Post-Production issues. Roles and Responsibilities of Business Analyst Why there is a Software Development Life Cycle necessary? Software Development Life Cycle is needed in any of the project for the below reasons: Software Development Life Cycle Models : Some of the SDLC Models are as follows : Which phase takes all the detailed design documents from the design phase and transforms them into the actual system?The implementation phase involves taking all of the detailed design documents from the design phase and transforming them into the actual system.
What is the process of transferring information from a legacy system to a new system?System migration is the process of transferring old IT systems to a newer hardware infrastructure or software platform to keep up with current technologies.
Which phase of the SDLC establishes descriptions of the desired features and operations of the system?SDLC Phase 3: Systems Design
Phase 3 of the systems development life cycle describes the desired features and operations of the system. The objective of the systems design phase is to transform all requirements into detailed specifications covering all aspects of the system.
What is the overall process for developing information systems from planning and analysis through implementation and maintenance?The SDLC is the overall process for developing information systems from planning and analysis through implementation and maintenance.
