Having covered the major SDLC methodologies offered by software development companies, let’s now review whether they are actually worth employing. As you can see, different methodologies are used depending on the specific vision, characteristics, and requirements of individual projects. Knowing the structure and nuances of each model can help to pick the one that best fits your project. The verification and validation model tends to be resource-intensive and inflexible. For projects with clear requirements where testing is important, it can be useful.

  • SDLC is used across the IT industry, but SDLC focuses on security when used in context of the exam.
  • The waterfall approach is best suited for a simplistic, yet systematic approach to meet the exact requirements of the client.
  • The purpose of this new UI was to create websites, mobile solutions, and intranets for companies and manage them in an efficient manner.
  • The software development life cycle (SDLC) is the process of planning, writing, modifying, and maintaining software.
  • Ultimately, any development team in both the IT and other industries can benefit from implementing system development life cycles into their projects.
  • DevOps also enables developers to develop and execute code faster by removing manual steps.
  • The system typically consists of several hardware and software components that work together to perform complex functions.

The objective of this activity is to extend as long as possible the life cycle of an existing system. When this is not longer feasible or efficient, the system life cycle terminates and a new SDLC commences. With that in mind, Intellectsoft’s best experts have created a complete guide to the system development life cycle. You’ll learn about its core meaning and phases, major software engineering methodologies, and the most important benefits it can provide during project development. This phase often requires extensive programming skills and knowledge of databases.

Basic 6 SDLC Methodologies

The software generation process has become much faster thanks to the incremental method. Moreover, this method is flexible enough as it leads developers to make changes at any stage of development. Also, clients can easily approach each build and quickly identify any errors.

The detail design and development is responsible for producing the product, process and material specifications and may result in substantial changes to the development specification. This stage involves deploying the developed system into the production environment. This includes activities such as system installation, data migration, training end-users, and configuring necessary infrastructure. Implementation requires careful planning and coordination to minimize disruptions and ensure a smooth transition from the old system to the new one.

The System Development Life Cycle (SDLC) provides a well-structured framework that gives an idea, of how to build a system. It consists of steps as follows- Plan, Analyze, example of system development life cycle Design, Develop, Implement and Maintain. We will delve into the significance of each stage, emphasizing the critical role played by System Design in the overall process.

New versions of a software project are produced at the end of each phase to catch potential errors and allow developers to constantly improve the end product by the time it is ready for market. The development stage is the part where developers actually write code and build the application according to the earlier design documents and outlined specifications. The system specification represents the technical requirements that will provide overall guidance for system design. The most flexible of the SDLC models, the spiral model is similar to the iterative model in its emphasis on repetition. The spiral model goes through the planning, design, build and test phases over and over, with gradual improvements at each pass.


After deployment, the launch may involve marketing your new product or service so people know about its existence. If the software is in-house, it may mean implementing the change management process to ensure user training and acceptance. Application lifecycle management (ALM) is the creation and maintenance of software applications until they are no longer required. 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. In traditional software development, security testing was a separate process from the software development lifecycle (SDLC).

It’s mostly used to develop broad ideas when the customer or client isn’t sure what they want. Perhaps most importantly, the planning stage sets the project schedule, which can be of key importance if development is for a commercial product that must be sent to market by a certain time. The biggest difference between the lean methodology and the other methodologies is that the system’s full set of requirements is unknown when the project is launched.


Teams are mainly large, and everyone on the team works within their silos. It’s when you gather the team to brainstorm, set goals, and identify risks. At this stage, the team will work together to devise a set of business goals, requirements, specifications, and any high-level risks that might hinder the project’s success.

T’s important that the software overall ends up meeting the quality standards that were previously defined in the SRS document. Baselines[clarification needed] are established after four of the five phases of the SDLC, and are critical to the iterative nature of the model.[21] Baselines become milestones. For example, as the system analyst of Viti Bank, you have been tasked to examine the current information system. Customers in remote rural areas are finding difficulty to access the bank services.

Strategic Planning for/of Information Systems

The development team enters the coding phase of the software once the entire architecture, data structures, and functional software designs are ready. The Software Development Life Cycle (SDLC) models can provide developers with a robust structure to ensure a smoother transition from the beginning to the end of a project. In addition, the entire SDLC process can be narrowed down to the form of different models that can be used for project-based work. These steps remain the same in any software testing process, but their duration may vary as per project size and business requirements. Most solution providers use the waterfall life cycle approach for software solution development.

The software life cycle clearly outlines every stage of software development by fragmenting the entire process into various phases. It even follows a plan that eliminates bottlenecks of development projects. This includes all the specifications for software, hardware, and network requirements for the system they plan to build. This will prevent them from overdrawing funding or resources when working at the same place as other development teams.

What is the system development life cycle?

If the team does not perform diligently at any stage, the final product would come out damaged or low-quality. After this, they should focus on threat modeling, which basically means testing the software’s high-security-risk environments and scenarios. The main point of concern in the Iterative model is the concentration on repetitiveness. In this, the top software developers who are using this particular version of the SDLC Example make it very quickly. Whether it is a mobile device, PC, server, or MAC, you have to use the software on these devices. Overall, the main purpose at this stage is to make the software you developed accessible to end-users.
