This phase often requires extensive programming skills and knowledge of databases. The team will build functionality for the product or service, which includes creating a user interface and building the database so users can store information in your system. The SDLC life cycle process is repeated, with each release adding more functionality until all requirements are met. In this method, every cycle act as the maintenance phase for the previous software release. Modification to the incremental model allows development cycles to overlap.

As the RAD Model allows for rapid and easy software changes based on feedback from stakeholders and end users, it is best suited for projects with fast-paced and rapidly changing requirements. Rapid prototyping is also ideal for projects requiring a high degree of user involvement, since it encourages stakeholders and end users to participate early and in the development process. With its customizable spreadsheet interface and powerful collaboration features, Smartsheet allows for streamlined project and process management. Use Smartsheet’s SDLC with Gantt template to get started quickly, and help manage the planning, development, testing, and deployment stages of system development. Create a timeline with milestones and dependencies to track progress, and set up automated alerts to notify you as anything changes.

Which SDLC model is the best and most commonly used?

Each iteration of the spiral model builds on the previous one and reduces the overall project risk. As the spiral model allows for risk analysis and development to take place simultaneously, it is best suited for complex, high-risk projects that can be adapted based on the results of each iteration. SDLC provides one of the highest levels of software project management, control, and documentation. At its core, SDLC ensures all developers and stakeholders have a firm grasp on the project’s “why” and the direction they must follow to arrive at their unified goal. In essence, PDLC is structured to guarantee that products undergo rigorous design, development, and testing processes.

System Design is a critical stage in the SDLC, where the requirements gathered during the Analysis phase are translated into a detailed technical plan. 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. During the Analysis stage, the focus is on gathering and understanding the requirements of the system. This includes conducting interviews, studying existing processes, and identifying stakeholders’ needs.


There is a lot of literature on specific systems development life cycle (SDLC) methodologies, tools, and applications for successful system deployment. 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. In most use cases, a system is an IT technology such as hardware and software. Project and program managers typically take part in SDLC, along with system and software engineers, development teams and end-users.

  • However, there is little room for change once a phase is considered complete, as changes can affect the software’s delivery time, cost, and quality.
  • You should also evaluate and select the appropriate hardware, software, and network resources for your system.
  • The stages include Planning, Analysis, Design, Development, Implementation, and Maintenance.
  • You can use this software quality management process for both small-scale projects and large-scale enterprise applications.
  • The team estimates costs, creates a schedule, and has a detailed plan to achieve their goals.
  • In essence, PDLC is structured to guarantee that products undergo rigorous design, development, and testing processes.
  • In this third phase, the system and software design documents are prepared as per the requirement specification document.

This article provides an in-depth look into SDLC, its significance for PMs, and practical examples to navigate each phase. Technological advancements continually redefine possibilities, setting new standards and expectations. Competition fuels the drive for differentiation and excellence, while organizational resources, both human and financial, form the backbone of the development process. A deep dive into each of these stages reveals the complexity and significance of every step, underlining the importance of strategic execution for achieving product success in today’s dynamic market.

What is Product Life Cycle?

This stage gives a clearer picture of the scope of the entire project and the anticipated issues, opportunities, and directives which triggered the project. Here, are prime reasons why SDLC is important for developing a software system. Empower your people to go above and beyond with a flexible platform designed to match the needs of your team — and adapt as sdlc system development life cycle those needs change. Find security issues early with the most accurate results in the industry and fix at the speed of DevOps. In addition, ValueEdge offers reporting and analytics features that can help improve project visibility. These features allow key project stakeholders to see which areas of the project are on track and which areas need improvement.

By its core principles, we mean adaptability, customer involvement, lean development, teamwork, time, sustainability, and testing, with its two primary elements being teamwork and time (faster delivery). So rather than creating a timeline for the project, agile breaks the project into individual deliverable ‘time-boxed’ pieces called sprints. This model prioritizes flexibility, adaptability, collaboration, communication, and quality while promoting early and continuous delivery. Ultimately, all this ensures that the final product meets customer needs and can quickly respond to market demands.

DevSecOps is the practice of integrating security testing at every stage of the software development process. It includes tools and processes that encourage collaboration between developers, security specialists, and operation teams to build software that can withstand modern threats. In addition, it ensures that security assurance activities such as code review, architecture analysis, and penetration testing are integral to development efforts. Developing a new customer relationship management (CRM) system for a sales organization is an example of a project that can use the V Model. The waterfall model provides discipline to project management and gives a tangible output at the end of each phase. However, there is little room for change once a phase is considered complete, as changes can affect the software’s delivery time, cost, and quality.

This ensures they not only meet the envisioned specifications but are also aligned with user expectations and market demands. The abbreviation SDLC can sometimes refer to the systems development lifecycle, the process for planning and creating an IT system. The system typically consists of several hardware and software components that work together to perform complex functions. The iterative process suggests that teams begin software development with a small subset of requirements. Then, they iteratively enhance versions over time until the complete software is ready for production. The final stage of the software development life cycle is maintenance and operations.

What is the purpose of product development?

The senior members of the team perform it with inputs from all the stakeholders and domain experts or SMEs in the industry. Next, let’s explore the different stages of the Software Development Life Cycle. The final phase of the SDLC is to measure the effectiveness of the system and evaluate potential enhancements.

Developers use the methodology as they design and write modern software for computers, cloud deployment, mobile phones, video games, and more. 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. The system development should be complete in the pre-defined time frame and cost.

Stage 5: Test the product.

After the code is generated, it is tested against the requirements to make sure that the products are solving the needs addressed and gathered during the requirements stage. Business analyst and Project organizer set up a meeting with the client to gather all the data like what the customer wants to build, who will be the end user, what is the objective of the product. Before creating a product, a core understanding or knowledge of the product is very necessary.
