What is Systems Development Life Cycle? Definition from WhatIs com

In the fifth phase, systems integration and testing are carried out by Quality Assurance (QA) professionals. They will be responsible for determining if the proposed design reaches the initial business goals set by the company. It’s possible for testing to be repeated, specifically to check for bugs, interoperability, and errors. In the first phase, the team determines whether or not there’s a need for a new system to reach the strategic objectives of a business. This is a feasibility study or preliminary plan for the company to acquire any resources necessary to improve a service or build on specific infrastructure.

  • By the end of the project, all features must be developed to present a final product.
  • Moreover, the deployment of a big and complex application can be a project in itself.
  • It can also be used to develop hardware or a combination of both software and hardware at the same time.
  • Requirements Gathering Template
    The free requirements gathering template for Word collects everything you’re going to need in the design and development of your software product.
  • In case a priority is fast getting to the
    market, then a RAD or agile SDLC methodologies will be a more suitable option.

A high flexibility level makes a development process
adaptable to dynamic market conditions, ensuring that a client will get a relevant product
in the end. Also, active customer involvement minimizes the risk of investing in a software
solution that doesn’t satisfy user needs. The iterative model in SDLC implies that software may have different builds at the same time to see what version works best. However, development of each build should contain such processes as design and development, testing, and implementation. It means that a project starts with a determination of a short list of requirements that relate to the most basic software features.

What You Need to Know About System Development Life Cycle

This can include handling residual bugs that were not able to be patched before launch or resolving new issues that crop up due to user reports. Larger systems may require longer maintenance stages compared to smaller systems. Developers must now move into a maintenance mode and begin practicing any activities required to handle issues reported by end-users. After testing, the overall design for the software will come together.

This methodology relies heavily on two foundational credos, including continuous improvement and respect for people. Among other things, the development team will mull over the core components, structure, processing, and procedures for the system to reach the stated goal. Thus, the analysis phase helps you understand your core business needs and what you should do to fulfill them. Each step in an SDLC results in an output (document, diagram, working software, etc.) that acts as the necessary input for the next step. Despite this funnel-like approach, modern SDLC strategies are not strictly linear.


This SDLC tool is a key element in managing software customizations that meet the needs of the project. Git allows developers to have multiple local branches that can be entirely independent of each other. This web service is geared towards teamwork without traditional ways of information exchange and with no mobile applications. Most of you have probably heard of or even worked on Trello and Basecamp. Asana is less well known, but it has reacher functionality than the popular Basecamp, while maintaining a clear interface, unlike Trello.

After that subsequent cycle may begin before the previous cycle is complete. SDLC is a systematic process for building software that ensures the quality and correctness of the software built. SDLC process aims to produce high-quality software that meets customer expectations.

This helps to see when activities are scheduled to start and end and to check all those that are on the critical path. PMS also offer test management options where test results and history can be tracked. Also, regression analysis can quickly generate through the system using acceptance test and other new trials. The system development life cycle (SDLC) is an iterative, structured, and multistep process that is used by teams to create high-quality information systems. It involves the activities of planning, analysis, designing, building, testing, deploying, and maintaining a system that meets or exceeds client expectations.

Once that step is done, you can select the right SDLC methodology or a hybrid of models that is perfectly suited to your main project requirements and expected end result. SDLC has been around since the 1960s—a time when teams were more centralized. As the information technology sphere continues to evolve, the SDLC has been changed to keep up with the ever-changing demands in system development.

Software Testing

This also involves addressing any bugs that may still be present in the system. Maintenance must continue to help make improvements to the now fully-implemented information system. Finally, after extensive testing from the QA team, the information system is brought into production. While there are still a few more steps, the implementation phase is where end-users already start using the product. Compared to all other phases of the system development life cycle, the development phase is considered the most robust. In the development phase, the company is all-in on the project, and the information system is built to specification.

Before we even begin with the planning stage, the best tip we can give you is to take time and acquire proper understanding of app development life cycle. ProjectManager is award-winning software that connects hybrid teams at any time and anywhere. We have features that manage https://www.globalcloudteam.com/ every part of the software development cycle. This is when you elaborate on a project plan for meeting those requirements laid out by the customer. Once you have a plan, design concrete specifications for the developers to utilize, like screen layouts and other materials.

Why Is Software Development Life Cycle Important?

There is a lot of literature on specific systems development life cycle (SDLC) methodologies, tools, and applications for successful system deployment. Books such as David Avison and Guy Fitzgerald’s Information Systems Development and Alan Daniels and Don Yeates’ Basic Systems Analysis, delve into the intricacies of information systems development lifecycles. 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. The systems development life cycle allows lowering the complexity usual for developing a
proposed system from scratch.

Systems Development Life Cycle is a systematic approach which explicitly breaks down the work into phases that are required to implement either new or modified Information System. In systems design, functions and operations are described in detail, including screen layouts, business rules, process diagrams, and other documentation. Modular design reduces complexity and allows the outputs to describe the system as a collection of subsystems.


The biggest drawback of this model is that small details left incomplete can hold up the entire process. Application performance monitoring (APM) tools can be used in a development, QA, and production environment. This keeps system development life cycle project management everyone using the same toolset across the entire development lifecycle. Once the software is complete, and it is deployed in the testing environment. The testing team starts testing the functionality of the entire system.
