We look at some popular SDLC models below. Different models arrange the SDLC phases in varying chronological order to optimize the development cycle. In addition, the team monitors overall system performance, security, and user experience to identify new ways to improve the existing software.Ī software development lifecycle (SDLC) model conceptually presents SDLC in an organized fashion to help organizations implement it. In the maintenance phase, among other tasks, the team fixes bugs, resolves customer issues, and manages software changes. The deployment phase includes several tasks to move the latest build copy to the production environment, such as packaging, environment configuration, and installation. Having separate build and production environments ensures that customers can continue to use the software even while it is being changed or upgraded. The software that customers use is called production, while other copies are said to be in the build environment, or testing environment. When teams develop software, they code and test on a different copy of the software than the one that the users have access to. Because many teams immediately test the code they write, the testing phase often runs parallel to the development phase.
Quality analysis includes testing the software for errors and checking if it meets customer requirements.

The development team combines automation and manual testing to check the software for bugs. They analyze the requirements to identify smaller coding tasks they can do daily to achieve the final result. In the implementation phase, the development team codes the product.

They will look at how to best integrate the new software into any existing IT infrastructure the organization may have. For example, they may consider integrating pre-existing modules, make technology choices, and identify development tools. In the design phase, software engineers analyze requirements and identify the best solutions to create the software. The team estimates costs, creates a schedule, and has a detailed plan to achieve their goals. The document sets expectations and defines common goals that aid in project planning. The development team collects requirements from several stakeholders such as customers, internal and external experts, and managers to create a software requirement specification document. The planning phase typically includes tasks like cost-benefit analysis, scheduling, resource estimation, and allocation.
However, we outline some common SDLC phases below.
The details of the SDLC process vary for different teams. The development process goes through several stages as developers add new features and fix bugs in the software. The software development lifecycle (SDLC) outlines several tasks required to build a software application.
