Every phase can be supplemented by various tools to support the phase’s main goal. Now that you know the basic SDLC phases and why each of them is important, it’s time to dive into the core methodologies of the system development life cycle. Similarly, automated and cloud-based platforms, which simulate testing environments, take a significant amount of manual time out of this stage of the system development life cycle. Selenium, a browser testing tool, is one popular example of such a platform. There are various approaches to testing, and you will likely adopt a mix of methods during this phase.
The verification and validation model tends to be resource-intensive and inflexible. For projects with clear requirements where testing is important, it can be useful. The last but not least important stage of the SDLC process is the maintenance stage, where the software is already being used by end-users. It is often incorrectly equated with the actual development process but is rather an extensive prototyping stage.

The System Development Life Cycle encompasses a series of interconnected stages that ensure a systematic approach to system development. The stages include Planning, Analysis, Design, Development, Implementation, and Maintenance. Each stage contributes to the successful completion of the system, with System Design serving as a crucial component. During this step, current priorities that would be affected and how they should be handled are considered. A feasibility study determines whether creating a new or improved system is appropriate. This helps to estimate costs, benefits, resource requirements, and specific user needs.
Most of the information generated at this stage will be contained in the SRS. This document shapes the strict regulations for the project and specifies the exact software model you will eventually implement. Once the planning is done, it’s time to switch to the research and analysis stage. Each of them requires different specialists and diverse skills for successful project completion. Modern SDLC processes have become increasingly complex and interdisciplinary.

The goal of TechTerms.com is to explain computer terminology in a way that is easy to understand. We strive for simplicity and accuracy with every definition we publish. If you have feedback about this definition or would like to suggest a new technical term, please contact us. It’s easy to identify and manage risks, as requirements can change between iterations.
SDLC can be used to develop or engineer software, systems, and even information systems. It can also be used to develop hardware or a combination of both software and hardware at the same time. Again, since SDLCs utilize extensive paperwork and guideline documents, it’s a team effort and losing one even major member will not jeopardize the project timeline. The agile methodology prioritizes fast and ongoing release cycles, utilizing small but incremental changes between releases.
Software Quality
Changes are passed through the different SDLC phases again and again in a so-called “spiral” motion. In the greater context of management information systems or MIS, SDLC helps managers to design, develop, test, and deploy information systems to meet target goals. SDLC provides a number of advantages to development teams that implement it correctly.
- This high-level description is then broken down into the components and modules which can be analyzed, designed, and constructed separately and integrated to accomplish the business goal.
- New versions of a software project are produced at the end of each phase to catch potential errors and allow developers to constantly improve the end product by the time it is ready for market.
- They will look at how to best integrate the new software into any existing IT infrastructure the organization may have.
- This includes activities such as system installation, data migration, training end-users, and configuring necessary infrastructure.
- It takes them days or even weeks to travel to a location to access the bank services.
- During the fifth phase the system is installed in the production environment.
If this is done in the production environment, this is usually done by a Quality Assurance professional. He or she will determine if the proposed design meets the company’s goals. The testing must be repeated, if necessary, until the risk of errors and bugs has reached an acceptable level. This is especially the case when a programmer, https://www.globalcloudteam.com/ engineer, or database developer is called in to do important work for the developed project. These operations consist of, amongst other things, making flowcharts that ensure that the process and new system are carefully organised. By adding new steps, developers could define clearer and more effective actions to reach certain goals.

Once you’ve come up with some ideas, it’s time to organize them into a cohesive plan and design. This requires a lot of research and planning to ensure that your final product meets your expectations (and those of your customers). The big step is creating a detailed project plan document and work breakdown structure that outlines the requirements. Each stage in the SDLC has its own set of activities that need to be performed by the team members involved in the development project. While the process timeline will vary from project to project, the SDLC generally follows the seven stages outlined below.
The gathered information serves as a basis for designing a system that meets users’ expectations and addresses organizational challenges. The System Development Life Cycle (SDLC) provides a well-structured framework that gives an idea, of how to build a system. It consists of steps as follows- Plan, Analyze, Design, Develop, Implement and Maintain. We will delve into the significance of each stage, emphasizing the critical role played by System Design in the overall process. After training, systems engineers and developers transition the system to its production environment. Relevant questions include whether the newly implemented system meets requirements and achieves project goals, whether the system is usable, reliable/available, properly scaled and fault-tolerant.
System Development Life Cycle Phases (SDLC)
When teams develop software, they code and test on a different copy of the software than the one that the users have access to. The software that customers use is called production, while other copies are said to be in the build environment, or testing environment. The project manager is the overall control agent for a strong SDLC process. The most flexible of the SDLC models, the spiral model is similar to the iterative model in its emphasis on repetition.
Security is critical – especially when the purpose of the system development life cycle is to create software. Software is the most-attacked part of the security perimeter, and more than half of all successful security breaches begin with an attack on an application.

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.
Analysis Stage
These elements describe the system in sufficient detail that developers and engineers can develop and deliver the system with minimal additional input. Rapid development cycles help teams identify and address issues in complex projects early on and before they become significant problems. They can also engage customers and stakeholders to definition of system development life cycle obtain feedback throughout the project lifecycle. However, overreliance on customer feedback could lead to excessive scope changes or end the project midway. In the implementation phase, the development team codes the product. They analyze the requirements to identify smaller coding tasks they can do daily to achieve the final result.
