7 Phases of System Development Life Cycle

No comments yet

User Acceptance Testing (UAT) – also known as beta-testing, tests software in the real world by the intended audience. White-Box Testing – tests internal structures or workings of an application giving an internal perspective of the system. Black-Box Testing – examines the functionality of an application without peering into its internal structures or workings. Path Testing – ensures that every path through a problem has been executed at least once. Technical Feasibility – confirms the system will perform and verifies there are no production barriers. This is the phase where where the data and components from the old system are moved to the new one.

Once all planning and requirements are in place, the plans are handed over to the systems architect who can then start working on the design of the systems. Often the systems to be designed are based on software or IT infrastructure. This means that the systems development designers will likely be IT specialists or software developers. The iterative and phased stages of an SDLC benefit from the leadership of a dedicated project manager.

Stage 5: Implement

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.

It is also important that the system undergoes frequent maintenance so that can continue to run smoothly. However, regardless of the model you pick, there are a lot of tools and solutions, like Stackify’s Retrace tool, to assist you every step of the way. “Let’s get this closer to what we want.” The plan almost never turns out perfect when it meets reality.


It involves designing the system’s architecture, database structure, and user interface, and defining system components. The Design stage lays the foundation for the subsequent development and implementation phases. It’s critical that the program meets the quality requirements outlined in the SRS document.C++, PHP, and other programming languages are examples of common programming languages. Based on the project specs and requirements, developers will select the appropriate programming code.

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. 7 stages of the System Development Life Cycle offer a lot of benefits to development teams who use it properly. This can include resolving new issues that arise as a result of user reports or dealing with leftover bugs that were not able to be corrected before launch. In comparison to smaller systems, larger systems may require more maintenance phases.

System Development Life Cycle Models

Without using an exact life cycle model, the development of a software product would not be in a systematic and disciplined manner. When a team is developing a software product, there must be a clear understanding among team representative about when and what to do. Suppose a software development issue is divided into various parts and the parts are assigned to the team members.

It entails determining and defining the project scope in order to develop a complete action plan for the project, as well as identifying the issues that the solution will address. This post offers a thorough examination of the system development life cycle. You will understand what an SDLC is, the 7 stages of the system development life cycle, and why it is vital by reading it. This word has been around for many decades and stems from a time when organizations were much more centralized. Still, as IT as a field and IT services as a market have evolved, SDLC has become an integral aspect of how custom software development company develop software solutions. Once the requirement analysis is done, the next stage is to certainly represent and document the software requirements and get them accepted from the project stakeholders.

Stages of System Development Life Cycle

New or changed backlog items can be scheduled for the next iteration, allowing for changes to be made over several weeks. In conclusion, we now know that Software Development Life Cycle (SDLC) software engineering is an important framework for the better and more structured development of optimized software programs. In a world full of rapid evolution in technology, SDLC phases plays a crucial role in enabling some good and innovative solutions for helping users and organizations. Also, it’s better to adapt SDLC principles to achieve software development goals effectively. 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 article will provide an in-depth analysis of the history, definition, phases, benefits, and disadvantages, along with solutions that support the system development life cycle. SDLC products from software vendors promise organizational clarity, phases of the systems development life cycle modern process development procedures, legacy application strategies, and improved security features. Vendors such as Oracle, Airbrake, and Veracode provide software development solutions in their complete enterprise software offerings.

What is the software development life cycle (SDLC)?

SDLC models describe the overall process and phases involved in software development. Scrum, on the other hand, is a specific Agile framework used within https://www.globalcloudteam.com/ the SDLC to manage and structure development. It focuses on sprints (short development cycles) and collaboration among cross-functional teams.

SDLC comprises a detailed description or step-by-step plan for designing, developing, testing, and maintaining the software. Software development can be challenging to manage due to changing requirements, technology upgrades, and cross-functional collaboration. The software development lifecycle (SDLC) methodology provides a systematic management framework with specific deliverables at every stage of the software development process.

Benefits of a Well-Defined System Development Life Cycle

It is the first phase of the system development process where it identifies if a new system is needed or not to achieve the desired objective. This phase is a type of feasibility study for an organization’s business initiative to acquire in order to build an infrastructure to improve or modify a service. Primarily, there were only five phases in the system development life cycle, but two additional phases were added to help the system analysts to achieve specific goals by having clearer actions. Each of the testing steps in the development/configuration phase is tested against a step in the design phase. This ensures that the objective of the system is met and that it is fit for purpose. During this stage, if there any changes need in the system then the software developers are responsible for implementing.

  • One of the most important advantages of the waterfall model is simplicity—a team cannot go forward if the work on the previous stage is not completed.
  • Operations refer to the day-to-day running of a software product or service, such as performing backups and other administrative tasks.
  • The Smartsheet platform makes it easy to plan, capture, manage, and report on work from anywhere, helping your team be more effective and get more done.
  • Conceptually, the design flows from one phase down to the next, like that of a waterfall.
  • It involves multiple processes, tools, and people working together to manage every lifecycle aspect, such as ideation, design and development, testing, production, support, and eventual redundancy.
