The abbreviation SDLC can sometimes refer to the systems development lifecycle, the process for planning and creating an IT system. The system typically consists of several hardware and software components that work together to perform complex functions. Once you’ve completed all testing phases, it’s time to deploy your new application for customers to use.
When it comes to web development projects, there are several frameworks and content management systems (CMS) available that make the process more efficient. For example, developers often use frameworks like React, Angular, or Vue.js to create dynamic and interactive web applications. CMS platforms like WordPress, Joomla, and Drupal provide pre-built templates and plugins, allowing developers to quickly set up and customize websites.
What Is SDLC? Understand the Software Development Life Cycle
One big disadvantage here is that it can eat up resources fast if left unchecked. The Agile SDLC model separates the product into cycles and delivers a working product very quickly. Testing of each release feeds back info that’s incorporated into the next version. According to Robert Half, the drawback of this model is that the heavy emphasis on customer interaction can lead the project in the wrong direction in some cases. Following the best practices and/or stages of SDLC ensures the process works in a smooth, efficient, and productive way.
These engines allow developers to create realistic graphics, implement physics simulations, and handle game logic. Also, these projects typically involve considerations for user experience, gameplay mechanics, and monetization strategies. Developers need to create immersive worlds, design challenging levels, and implement in-game purchases or advertisements to generate revenue. Game development projects can be divided into different stages, including concept development, game design, programming, artwork creation, and quality assurance. Each stage requires specialized skills and collaboration between team members.

Systems analysis and design (SAD) can be considered a meta-development activity, which serves to set the stage and bound the problem. 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. SDLC and SAD are cornerstones of full life cycle product and system planning. 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.
SDLC or the Software Development Life Cycle is a process that produces software with the highest quality and lowest cost in the shortest time possible. SDLC provides a well-structured flow of phases that help an organization to quickly produce high-quality software which is well-tested and ready for production use. But None of them is perfect, and each brings its favorable aspects and disadvantages for a specific software development project or a team.
Why Use SDLC?
SDLC comprises a detailed description or step-by-step plan for designing, developing, testing, and maintaining the software. Also, system software development projects often involve complex tasks such as memory management, process scheduling, and device driver development. These projects require meticulous testing and debugging to ensure that the software functions reliably and efficiently. One of the key concepts to understand in software development is the software development life cycle (SDLC). The SDLC is a framework that outlines the stages involved in developing software, from initial concept to final deployment and maintenance. Without using an exact life cycle model, the development of a software product would not be in a systematic and disciplined manner.
Around seven or eight steps appear commonly; however, there can be anywhere from five upwards to 12. Typically, the more steps defined in an SDLC model, the more granular the stages are. ALM includes the entire lifecycle of the application and continues beyond SDLC.
Test case development
In traditional software development, security testing was a separate process from the software development lifecycle (SDLC). The security team discovered security flaws only after they had built the software. This led to a high number of bugs that remained hidden as well as increased security risks. The development team combines automation and manual testing to check the software for bugs. Quality analysis includes testing the software for errors and checking if it meets customer requirements.
- The software development lifecycle (SDLC) outlines several tasks required to build a software application.
- If you haven’t yet started your journey as a software developer, you might ask yourself, “Is software development for me?
- Functional Requirements Document is a document or collection of documents that defines the function(s) of a software system or its components.
- 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.
- This methodology outlines a series of steps that divide the software development process into tasks you can assign, complete, and measure.
Developers use the methodology as they design and write modern software for computers, cloud deployment, mobile phones, video games, and more. Software development life cycle (SDLC) is the term used in the software industry to describe the process for creating a new software product. Software developers use this as a guide to ensure software is produced with the lowest cost and highest possible quality in the shortest amount of time.
New to software development?
The waterfall model is not in practice anymore, but it is the basis for all other SDLC models. Because of its simple structure, the waterfall model is easier to use and provides a tangible output. In the waterfall model, once a phase seems to be completed, it cannot be changed, and due to this less flexible nature, the waterfall model is not in practice anymore.
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 sdlc systems development life cycle expectations and fits within the overall budget. Hence, it’s vital for a software developer to have prior knowledge of this software development process.
Testing
The deployment phase includes several tasks to move the latest build copy to the production environment, such as packaging, environment configuration, and installation. 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.
