What Is SDLC? Understand the Software Development Life Cycle

Developers write code and build the app according to the finalized requirements and specification documents. That is why it’s highly recommended that project managers engage a dedicated team of professional developers. Such a team will possess enough expertise and knowledge to launch a first-class software product that perfectly corresponds to all your expectations, needs, and goals. These details are generally not dictated by the choice of model or general methodology.

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. Once the requirement analysis is done the next step is to clearly define and document the product requirements and get them approved from the customer or the market analysts. This is done through an SRS (Software Requirement Specification) document which consists of all the product requirements to be designed and developed during the project life cycle. SDLC is a process followed for a software project, within a software organization. It consists of a detailed plan describing how to develop, maintain, replace and alter or enhance specific software. The life cycle defines a methodology for improving the quality of software and the overall development process.

Despite this funnel-like approach, modern SDLC strategies are not strictly linear. The team often goes back a step or two in the SDLC to perform fixes or make improvements. While there are some drawbacks, SDLC has proven to be one of the most effective ways for successfully launching software products. It is important that you have contingencies in place when the product is first released to market should any unforeseen issues arise. Microservices architecture, for example, makes it easy to toggle features on and off.

Our team of content writers and experts have great knowledge in the latest software technologies, allowing them to break down even the most complex topics in the field. They also know how to tackle topics from a wide range of industries, capture their essence, and deliver valuable content across all digital platforms. This phase is where the development process is executed as your ideas and vision start to come to life. You might want to have daily meetings to ensure everyone is on track and that effective communication is taking place amongst team members.

Mastering Efficiency: The Key Stages of the Agile Software Development Life Cycle

The agile model is both iterative and incremental, making it more efficient than other process models. It then creates the software through the stages of analysis, planning, design, development, testing, and deployment. By anticipating costly mistakes like failing to ask the end-user or client for feedback, SLDC can eliminate redundant rework and after-the-fact fixes. Systems analysis and design (SAD) can be considered a meta-development activity, which serves to set the stage and bound the problem.

  • 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.
  • During the planning stage, the experienced software engineers will define the problem and scope of the existing systems and determine the objectives for building new systems.
  • Want to improve application quality and monitor application performance at every stage of the SDLC?
  • Builds evolve as teams add new features and improvements with each deployment.
  • Rigorous testing and quality assurance are performed to ensure the system’s accuracy, performance, and adherence to the design requirements.

The goal of the SDLC life cycle model is to deliver high-quality, maintainable software that meets the user’s requirements. The team should also create a project budget and timeline to ensure that the project is completed on time and within budget. The team should also create a quality assurance plan to ensure that the software meets the user requirements and is bug-free.


Secure SDLC (or SSDLC) is a software life cycle with fully integrated security checks at every phase. Teams start thinking about security risks and measures during the first stage of the SDLC. The agile approach requires the team to perform testing at the end of each sprint to ensure no potential exploits end up in production.

The planning or feasibility stage is the stage where professional software developers will plan for an upcoming project. The systems development life cycle originally consisted of five stages instead of seven. Flatlogic Platform – is a platform that provides developers with the tools they need to quickly and efficiently build web applications using the SDLC. Flatlogic Platform software systems development life cycle does offer the potential to speed up development by 20% or more compared to traditional manual software development processes. The platform’s automated tools, streamlined workflow, and comprehensive analytics all help to reduce the amount of time and effort required to complete projects. This can result in a notable improvement in development speed and efficiency.

Significance of System Design

In those days, teams were small, centralized, and users were ‘less’ demanding. This type of scenario meant that there was not a true need for refined methodologies to drive the life cycle of system development. However, technology has evolved, systems have become increasingly complex, and users have become accustomed to well-functioning technology. Models and frameworks have been developed to guide companies through an organized system development life cycle.

Thanks to their iterative and flexible approach, among other advantages, Agile methodologies have become a top software development model choice for many developers. In this article, we’ll highlight the reasons why and provide a comprehensive overview of the Agile SDLC, its key stages, and how to master efficiency in each phase. System Design is a crucial stage in the SDLC as it bridges the gap between requirements analysis and system development.

SDLC Meaning (Software Development Life Cycle)

The SDLC Design Phase is the third part of the software development life cycle. During this phase, the team will create the software architecture, design the user interface, and code the software. The design should include all of the user requirements, system functions, and features that were identified in the analysis phase. The team should also create a test plan to ensure that the software meets the user requirements and is bug-free. The design phase is critical to ensure that the software is user-friendly and meets all of the project requirements.

For example, It can diagram easily for a resource flow or a business process. Or, famous IDE(e.g. Eclipse, Intellij, Visual Studio) also gives detailed error of the https://www.globalcloudteam.com/ program for developers. Once when the client starts using the developed systems, then the real issues come up and requirements to be solved from time to time.


It is important to ensure that the maintenance phase is properly managed to ensure the success of the project. As we know, the software development life cycle (SDLC) is a systematic process that outlines the steps involved in developing a software product. Think of it as a blueprint for software developers, ensuring that they create high-quality software in an organized and efficient manner. The waterfall model provides discipline to project management and gives a tangible output at the end of each phase.
