The testing team starts testing the functionality of the entire system. Each phase produces deliverables required by the next phase in the life cycle. Analysis is very important to proceed further to the next step. Additionally, this phase involves the actual installation of the newly-developed system. Software Development Life Cycle begins with Requirement Analysis phase, where the stakeholders discuss the requirements of the software that needs to be developed to achieve a goal. The importance of a central source control repository cannot be overstated. Waterfall is considered by many to be too rigid to adapt to changing requirements. The testing phase of the SDLC is arguably one of the most important. The Software Development Life Cycle of an application or system continues, with updates and new features, until the day it is decommissioned or replaced.
SDLC stages cover the complete life cycle of a software i.e.

What Is Software Development Life Cycle (SDLC) Definition and Phases
Software life cycle models describe phases of the software. Known as software development life cycle, these steps include planning, analysisdesign, development & implementation, testing and maintenance.
Architects may use an architecture framework such as TOGAF to compose an application from existing components, promoting reuse and standardization.

SDLC Phases Software Development Life Cycle
The third phase describes, in detail, the necessary specifications, features and operations that will satisfy the functional requirements of the proposed system which will be in place. Implementation After the requirements and design activity is completed, the next phase of the Software Development Life Cycle is the implementation or development of the software.
Software must be monitored constantly to ensure proper operation.

What is SDLC Understand the Software Development Life Cycle
The software development life cycle (SDLC) is a process used for structuring the development of any software system, from initiation through to. The System Development Life Cycle, "SDLC" for short, is a multistep, iterative process, structured in a methodical way. This process is used to model or provide .
Requirements Gathering stage need teams to get detailed and precise requirements.
Agile emphasizes teamwork, prototyping, and feedback loops that can change the direction of the development effort in response to changing requirements.
If there is a problem, the CI system alerts the developers. Thanks for sharing such a knowledge about software development life cycle model i.
Following proper CI practices, no further work is done until the build is successful.
Waterfall methods tend to take each of these steps in turn. Testers can either use a test script to execute each test and verify the results, or use exploratory testing which is more of an experience based approach.
Those methods have adapted to the state of the art in computer hardware, development tools, and modern thinking about the organizational management of software development teams.
Each process model follows a particular life cycle in order to ensure success in process of software development. Testing may be repeated, specifically to check for errors, bugs and interoperability.
These steps are very roughly the same from one methodology to another. Whether a document, diagram, or working software, the artifact created in one step becomes the input to the next step.
This phase is the main focus of the project managers and stake holders. Once a defect is found, testers inform the developers about the details of the issue and if it is a valid defect, developers will fix and create a new version of the software which needs to be verified again.
