Software Development Life Cycle (SDLC) is a combination of phases that a project needs to get through from its start to its completion. The SDLC process involves several distinct stages, including planning, analysis, design, building, testing, deployment and maintenance. In this stage, the problem or pain the software targets is clearly defined. First, developers and other team members outline objectives for the system and draw a rough plan of how the system will work. Then, they may make use of predictive analysis and AI simulation tools at this stage to test the early-stage validity of an idea. This analysis helps project managers build a picture of the long-term resources required to develop a solution, potential market uptake, and which obstacles might arise.

  • Many organizations tend to spend few efforts on testing while a stronger focus on testing can save them a lot of rework, time, and money.
  • Simform is a top software development company with expertise in delivering enterprise-grade solutions to its clients.
  • A testing phase is incorporated into each development stage to catch potential bugs and defects.
  • In the greater context of management information systems or MIS, SDLC helps managers to design, develop, test, and deploy information systems to meet target goals.
  • My friend wanted to start the a company and reached out to me and others for guidance.
  • It can also include adding new features or functionality to a current product.
  • The Forensic Laboratory configuration management process is defined in Chapter 7, Section 7.4.5.

Needs and goals must be clearly defined and there should be no ambiguity early on in the development life cycle. With an SDLC method that fits your team, you can easily outline your goals, plan the project implementation, and produce a well-made product on time. This article will cover what a software development life cycle entails, best practices and common challenges, and 7 popular software development life cycle examples. SDLC works by lowering the cost of software development while simultaneously improving quality and shortening production time.

First, developers will take one final look at the new system and then work with content writers and quality assurance professionals to create detailed documentation. Including this, the development team can prepare for the product launch at this stage itself. To achieve the benefits of SDLC, one must follow a systematic plan as approaching software development problems chaotically may lead to project failure. This article provides an overview of SDLC, its popular models, and how it can help produce high-quality software. Even more rigid is the related Verification and Validation model — or V-shaped model.

Various SDLC methodologies have been developed to guide the processes involved, including the original SDLC method, the Waterfall model. Other SDLC models include rapid application development (RAD), joint application development (JAD), the fountain model, the spiral model, build and fix, and synchronize-and-stabilize. The planning phase typically includes tasks like cost-benefit analysis, scheduling, resource estimation, and allocation. The development team collects requirements from several stakeholders such as customers, internal and external experts, and managers to create a software requirement specification document. Each project has its own level of complexity in planning and execution, and often within an organization, project managers employ numerous SDLC methods.

But it is good to know it, because only then can you truly appreciate the value of SDLC agile. But, there are regular releases to take the benefits of smaller iterative cycles. People think of an idea, and they just work on it and build the product. However, this approach is extremely risky and is almost never followed by bigger companies. You can only introduce changes after one full interation has been completed. Understanding SDLC phases with examples will enable us to grasp the vastness of research that has happened in this field.

The waterfall approach (refer Figure 14.3) helps to understand the extent of the residual risks and allows one to work conscientiously toward reducing those risks. The third theme includes ways to determine the processes (actions) necessary to produce the results as defined by the requirements of the system. The V-Shaped model, also referred to as the Validation and Verification model, is based on the association of having a testing phase lined up for each corresponding development stage. The Waterfall model is ideal for offering high-level insight into long-term projects, but doesn’t provide visibility into the specific process details. Since the Waterfall model is more rigid than others, it can cause frustration with delayed testing and additional costs.


Cloud computing is one example where trust and trustworthiness39 between cloud service providers (CSPs) and a federal agency is critical for the effective application of the NIST RMF. This might require documenting the risk information needed to address the trust requirements in contracts, service level agreements (SLAs), or other forms of legal agreements. The waterfall approach is best suited for a simplistic, yet systematic approach to meet the exact requirements of the client. The immediate benefit to the client is the constant realization of the benefits in terms of the expectations of the final deliverable. This approach also ensures that the provider can constantly measure itself to interpret the requirements of – and deliver the best solution to – the client.

Phases in the life cycle can go in strict sequence, they can overlap, or go in a parallel. Also, think about the hand-off process at the beginning of the project. However, quite often you may see a relatively short phase for maintenance. You need to set up servers, upload your application, connect it with all the other services and servers. Be that a server, your PC or Mac, or a mobile device you need to deliver your application or service there. Ideally, your application should be stable and without serious defects all the time.

V-Shaped Model

Share your plan with your team and key stakeholders to provide visibility, and assign tasks to individuals to ensure nothing slips through the cracks. Finally, the planning process clearly defines the system development life cycle example outline of system development. The project manager will set deadlines and time frames for each phase of the software development life cycle, ensuring the product is presented to the market in time.

After making out the project motto and aim, you can hire dedicated developers to develop the concept. Hiren is VP of Technology at Simform with an extensive experience in helping enterprises and startups streamline their business performance through data-driven innovation. Software Development Life Cycle lays down a clear plan to build, improvise and maintain a software solution. Project Management approach can be different in different phases of the Life Cycle.

The deployment phase in SDLC is also something that is not heavy on the Product Manager. In the design phase in SDLC, you need to be as visual as possible about your vision. The design phase is the sole responsibility of the Product Manager, and you may work in tandem with UI/UX designers. The purpose of this new UI was to create websites, mobile solutions, and intranets for companies and manage them in an efficient manner. A company with a need to create a management solution for web content took the help of an SDLC Example.

One needs to upgrade the product as per system requirements and detect bugs to improve the user experience and future enhancements. Moreover, the developers may witness a bug or issue in the live software. Wireframes assist software engineers in making the development process faster and meeting customer requirements more effectively. In addition, they are an excellent way to test MVP (Minimum Viable Product) and get early feedback to reshape the product as per the client’s requirements.

Stages and Best Practices

Then the quality analysts start looking for errors, bugs, and other possible issues within the software. Next, they check the features against customer expectations and verify the product requirements. Generally, there are four to ten steps in the entire SDLC development process. However, the number of steps may slightly differ as per the applied methodology or the business goals. For instance, the Agile development process uses the iterative workflow, while the waterfall approach is a linear and documented process with terminal phases.
