What Is the Software Development Life Cycle? SDLC Explained

This will prevent them from overdrawing funding or resources when working at the same place as other development teams. A system development life cycle or SDLC is essentially a project management model. It defines different stages that are necessary to bring a project from its initial idea or conception all the way to deployment and later maintenance. The system integration and system testing are done in the fifth phase of the system development life cycle. This phase is normally carried out by Quality Assurance professionals to determine if the proposed design meets the initial business goals. Systems analysis and design (SAD) can be considered a meta-development activity, which serves to set the stage and bound the problem.

This may include addressing the remaining bugs that could not be patched prior to release or resolving new issues that surfaced based on user reports. This phase explores the components (hardware and/or software), structure (network capabilities), processes, and procedures that are essential for a system to achieve its goals. The Software Development Life https://www.globalcloudteam.com/ Cycle approach is used to help users see and understand the activities involved in a particular step. It is also used to let you know that you can repeat a step at any time or modify a previous step if you need to change or improve your system. This phase involves the use of a quality assurance team to ensure that everything is functioning as it should.

Phases of System Development Life Cycle (SDLC) – 9 Major Phases in SDLC Management Information System

Does it make sense from a technical and financial standpoint to green-light the project? The analysis phase will help a company figure out whether the projected success of the end product is worth pursuing or not. Thanks to the use of the SDLC, the process behind software engineering is not simply pushed to completion, but every step of the way is also documented and used for future projects. While it is true that its use has improved over time due to the advancement of technology, a lot of said advancement can be attributed to the multistep process.

Now it must be tested to make sure that there aren’t any bugs and that the end-user experience will not negatively be affected at any point. It helps to define the problem and scope of any existing systems, as well as determine the objectives phases of system development for their new systems. To make the most of this phase, you can start focusing on training during this phase. To manage and control a substantial SDLC initiative, a work breakdown structure (WBS) captures and schedules the work.

Systems Analysis & Design (SAD)

The System Development Life Cycle phases is a systematically structured, multi-step iterative process. Every phase of the SDLC is crucial to the success of any information system. This structure is the final product of years of research, and this approach will likely continue to improve with time. Individual phases of the application development life cycle help improve the chances of a project being successful. The first few phases also bring to light whether the project is even worth undertaking in the first place or not.

Testing is the fifth phases of SDLC which helps to verify appropriate testing and integration of each element in the system. Now we need to test to make sure there are no bugs and no negative impact on the end-user experience. The rest of the project will not make sense if the overall scope is not properly identified. Learners are advised to conduct additional research to ensure that courses and other credentials pursued meet their personal, professional, and financial goals. Gathering all of the specific details required for a new system, as well as defining the first prototype concepts, is part of the analysis step.


This results in more iterations and many more tests compared to other models. Their output may be closer or farther from what the client eventually realizes they desire. It’s mostly used for smaller projects and experimental life cycles designed to inform other projects in the same company. Furthermore, developers are responsible for implementing any changes that the software might need after deployment.

By increasing the number of steps, systems analysts were able to define clearer actions to achieve specific goals. Similar to the Project Lifecycle (PLC), Software Development Life Cycle uses a systematic approach to describe the process. If the thorough analysis phase ends with a positive outlook for the project, the design phase can begin. The design phase is where the real work starts, and company resources start to fund the project. It is also the phase where the team figures out what the finished product will look like once development is completed, omitting potentially risky design choices along the way.

History and Origin of the System Development Lifecycle

Quality software from this process can help companies in the software engineering industry and other businesses involved in information technology. The software development life cycle (SDLC) is the process of planning, writing, modifying, and maintaining software. Developers use the methodology as they design and write modern software for computers, cloud deployment, mobile phones, video games, and more.

  • It also allows for multiple teams to work on different phases at once without overlapping their tasks.
  • This phase begins when the developers build the application and deploy it in a test environment for quality assurance.
  • A system development life cycle or SDLC is an organized project management model that defines or involves different stages for developing and implementation of a system successfully.
  • If there is a problem, possible solutions are gathered and analyzed to find the best-fit for the project.
  • By making access to scientific knowledge simple and affordable, self-development becomes attainable for everyone, including you!

Choosing the correct SDLC can assist you in swiftly and successfully developing the system you require. As a result, IT consulting companies in New York are able to work in a regulated and well-organized setting, following a planned approach to the development of new solutions. The development stage is when programmers write code and build the application based on the design papers and specifications that were created earlier. Learning about major methodologies of SDLC, along with their benefits and drawbacks, enables you to set up effective system development processes that deliver the best possible outcomes.

Agile System Development Life Cycle Methodology

Here the system will be integrated into its environment and finally installed. This stage usually follows a testing period and a series of quality assurance tests. After all, successful tests have been completed and the final product delivered, it moves from an in-house project to that of an external business partner, who then takes care of distributing it to end-users.

During this stage, all security aspects, threats and constraints of system are discussed and considered to develop the system. When teams have clarity into the work getting done, there’s no telling how much more they can accomplish in the same amount of time. It’s critical to follow the seven phases of the System Development Life Cycle whenever you’re working on a new product. Developers have a clear understanding of the objectives they must achieve and the deliverables they must complete within a certain time frame, reducing the risk of wasting time and money. The information system will finally be built and incorporated into its environment. After clearing this stage, the program is considered market-ready and may be distributed to any end user.

H) Repair and maintenance

This phase identifies whether the system meets the initial requirements and objectives. The objective of the evaluation phase of the systems development life cycle is to deploy the system and train the system end users. Phase 6 of the initial development state of the systems development life cycle puts the software into production and runs as needed. If it performs the tasks correctly and represents the system, the developer moves on to the next phase of maintenance within the system development life cycle. Phase 4 of the systems development life cycle is when code is written for the desired features and operations.
