What is Software Development Lifecycle (SDLC)?
Learn how to create software that meets customer expectations and improves satisfaction using the software development life cycle (SDLC). The SDLC process consists of 7 main stages and 5 different methodologies, each with benefits and challenges.
- Project Initiation Phase. After the contract is signed, you get into the initiation phase. Here, you need to define what’s the goal of a project and its success criteria.
- Concept Development Phase. There are many different ways to develop software applications. I prefer to follow the design-first approach. So, how it works?
- Planning Phase. In large IT projects, you’ll need to create a full Project Management Plan. So, if you face such a task check out these articles: Practical Guide to Useful Project Management Plan.
- Requirements Definition Phase. After you plan how to manage the project, you need to find out what you need to develop. In this phase, you can use all the available options to define requirements
- Planning And Requirement Analysis: Planning is the crucial step in everything and so as in software development. In this same stage, requirement analysis is also performed by the developers of the organization.
- Defining Requirements: In this stage, all the requirements for the target software are specified. These requirements get approval from the customers, market analysts, and stakeholders.
- Designing Architecture: SRS is a reference for software designers to come out with the best architecture for the software. Hence, with the requirements defined in SRS, multiple designs for the product architecture are present in the Design Document Specification (DDS).
- Developing Product: At this stage, the fundamental development of the product starts. For this, developers use a specific programming code as per the design in the DDS.
- Waterfall Model. Waterfall model is the very first model that is used in SDLC. It is also known as the linear sequential model. In this model, the outcome of one phase is the input for the next phase.
- V-Shaped Model. V- Model is also known as Verification and Validation Model. In this model Verification & Validation goes hand in hand i.e. development and testing goes parallel.
- Prototype Model. The prototype model is a model in which the prototype is developed prior to the actual software. Prototype models have limited functional capabilities and inefficient performance when compared to the actual software.
- Spiral Model. The Spiral Model includes iterative and prototype approach. Spiral model phases are followed in the iterations. The loops in the model represent the phase of the SDLC process i.e.
Jul 24, 2023 · Various phases defined in SDLC are as follows: 1. Requirement Gathering and Analysis: As the name suggests, this involves gathering requirements, but requirements for what you may ask? The coding platform? Or the runtime environment? Or the User Interface? Or the Database? .. and so on.
Dec 13, 2023 · Phase 1: Planning. The initial stage of software development, Planning, involves defining the software’s purpose and scope, much like pinpointing our destination and plotting the best route. We uncover the tasks at hand during this phase and strategize for efficient execution.
SDLC is a process to design, develop, test, and maintain high-quality software. Learn about the stages, models, and benefits of SDLC with real-world examples and test management software.
