While the code still awaits advanced testing, the team should already put the product through basic tests (such as static code analysis and code reviews for multiple device types). The development team gets familiar with the DDS and starts working on the code. Typically, this step is the most time-consuming phase of SDLC, so we recommend using agile methodologies to speed up coding.
SDLC specifies the task(s) to be performed at various stages by a software engineer or developer. It ensures that the end product is able to meet the customer’s expectations and fits within the overall budget. Hence, it’s vital for a software developer to have prior knowledge of this software development process. Let’s take a close look at every typical phase of an average software development life cycle.

SDLC methodologies fit within a flexibility spectrum ranging from agile to iterative to sequential. Sequential or big-design-up-front (BDUF) models, such as waterfall, focus on complete and correct planning to guide larger projects and limit risks to successful and predictable results. [6] Anamorphic development is guided by project scope and adaptive iterations. SDLC is a method, approach, or process that is followed by a software development organization while developing any software. SDLC models were introduced to follow a disciplined and systematic method while designing software. With the software development life cycle, the process of software design is divided into small parts, which makes the problem more understandable and easier to solve.
A software life cycle model describes entry and exit criteria for each phase. So without a software life cycle model, the entry and exit criteria for a stage cannot be recognized. Without software life cycle models, it becomes tough for software project managers to monitor the progress of the project.
The SDLC Phases
Some try to systematize or formalize the seemingly unruly task of designing software. Large numbers of software projects do not meet their expectations in terms of functionality, cost, or delivery schedule – see List of failed and overbudget custom software projects for some notable examples. Software development organizations implement process methodologies software development life cycle definition to ease the process of development. Sometimes, contractors may require methodologies employed, an example is the U.S. defense industry, which requires a rating based on process models to obtain contracts. The international standard for describing the method of selecting, implementing, and monitoring the life cycle for software is ISO/IEC 12207.
In this article, We’ve listed the top five most popular SDLC models below.

Failure at this stage will almost certainly result in cost overruns at best and the total collapse of the project at worst. Planning is a crucial step in everything, just as in software development. In this same stage, requirement analysis is also performed by the developers of the organization. This is attained from customer inputs, and sales department/market surveys. This article goes through everything a company needs to know to adopt SDLC-based software development. We explain how SDLC strategies work, dive deep into each typical phase of a product’s life cycle, and present the market’s most reliable SDLC methodologies.
In order to guarantee the success of this modern software development model, an organization must be strategic in selecting tools that support and enhance this effort. As a proven leader in the application security field, Synopsys offers a comprehensive suite of products and services perfectly tailored to this effort. Software development life cycle (SDLC) is a structured process that is used to design, develop, and test good-quality software. SDLC, or software development life cycle, is a methodology that defines the entire procedure of software development step-by-step.
SDLC Meaning (Software Development Life Cycle)
While Agile is considered an SDLC approach to software development, there are some key differences. Agile also follows a continuous cycle and allows dynamic changes in requirements, whereas the SDLC is sequential, and requirement changes aren’t allowed after the initial stages. Finally, the SDLC relies heavily on the involvement of a project manager, and Agile requires close customer involvement. Conversely, Agile is a popular approach for organizations that want to create a continuous delivery environment. It’s centered around iterative development, short development cycles, gathering feedback and adapting to new requirements.
- Adopting an SDLC strategy also lowers your team’s technical debt since developers take little to no shortcuts during software creation.
- Whenever a user reports a bug or the team discovers a new flaw, the product moves back through its SDLC as many steps as necessary.

Having this DevSecOps mindset means more secure development, security testing, and continuous monitoring and protection in the CI/CD pipeline. The SDLC is also a repeatable process whose later phases feed back into the initial phases, enabling businesses to continually refine and improve their applications over time. The software development lifecycle gives organizations a systematic, step-by-step approach to developing successful software from gathering the initial requirements for a new product. We’ll teach you how to employ SDLC by maintaining a mature product on the market. Without clear objectives and processes, your software project runs the risk of getting derailed with no clear way to get back on track.
What is Agile Development?
These could include the overall system performance, user experience, new security vulnerabilities, an analysis of bugs or errors in the system. In the deployment phase, the software is officially released into the production environment. Application performance monitoring (APM) tools can be used in a development, QA, and production environment. This keeps everyone using the same toolset across the entire development lifecycle.
In other words, the team should determine the feasibility of the project and how they can implement the project successfully with the lowest risk in mind. Refer to our comparison of continuous delivery, deployment, and integration for an in-depth breakdown of the unique roles these practice play in an SDLC. They promptly respond to any bugs reported by users, and as needed, they introduce new features like bill payment or biometric sign-in. This includes addressing reported bugs, introducing new features, and optimizing overall software performance.

Read about DevOps security best practices to see what else companies are doing to boost the safety of their SDLCs and pipelines. Most teams rely on automated tests to speed up this phase, but some manual examinations are also valuable (penetration tests are a good example). It’s then released to the bank’s app store, such as Google Play Store or Apple’s App Store, making it accessible for download by the bank’s customers. This phase encompasses defining the system architecture, shaping the user interface and experience, and sculpting a database schema. The best SDLC model to use will depend on the specific needs of your project. This model is best suited for projects where speed and flexibility are important.
