System Development Life Cycle: Methodologies, Phases & Roles

It’s very common for the project teams to use UML diagrams in the design phase to design the system’s architecture. As a result, each stage will have roles of project participants who will take an active role in their tasks. In this article, we will focus on the main project roles which include the project manager, analyst, architect, developer, tester, and DevOps. It’s worth noting that each project participant plays an important role across the SDLC and they all have a direct impact on the overall wellbeing of projects. During the Analysis stage, the focus is on gathering and understanding the requirements of the system.

  1. The System Development Life Cycle resembles a step-by-step strategy for creating excellent PC programs.
  2. Often times, hiring cheaper and inexperienced developers throws out some of these standards.
  3. For this reason, the SDLCs first phase is planning where stakeholders and all parties involved in the project participate to clearly define requirements and the nature of what the information system will need to solve.
  4. Tools such as compilers, debuggers, and interpreters are utilized to ensure a smooth user experience.
  5. Do you have an upcoming software development project or existing software that has reached its maintenance stage?

At each stage, you will transfer the most valuable information throughout the project, focusing on the goals and objectives of the project, and making changes to the project where necessary to improve the user experience. LogRocket identifies friction points in the user experience so you can make informed decisions about product and design changes that must happen to hit your goals. With LogRocket, you can understand the scope of the issues affecting your product and prioritize the changes that need to be made.

The spiral model is a risk-driven hybrid model that features some of the traits of the waterfall model and Iterative model.

SDLC: Methodologies of System Development

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. The last but not least important stage of the SDLC process is the maintenance stage, where the software is already being used by end-users.

Developers can’t code for every eventuality; the fresh perspective that testing brings can help. In feasibility analysis, your team ensures that the project requirements help the end-user of the system. If you haven’t yet started your journey as a software developer, you might ask yourself, “Is software development for me? ” Here are some signs that this career path might be one that you will enjoy. SDLC models can thus assist projects in iterating and improving themselves until they are essentially ideal. Checks and balances are built into SDLC models to ensure that all software is thoroughly tested before being integrated into larger source code.

What is the System Development Life Cycle in MIS?

This stage includes the development of detailed designs that brings initial design work into a completed form of specifications. This work includes the specification of interfaces between the system and its intended environment, and a comprehensive evaluation of the systems logistical, maintenance and support requirements. 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 includes all the specifications for software, hardware, and network requirements for the system they plan to build.


Special attention has been given to the characteristics of each of the seven SDLC phases because a thorough understanding of these different stages is required to implement both new and modified software systems. Understanding the System Development Life Cycle is critical for any organization that wants to ensure that its product initiatives run smoothly. SDLC has several stages, from the beginning to the end, that help keep everything organized and profitable. The System Development Life Cycle resembles a step-by-step strategy for creating excellent PC programs. In addition, framework determinations have been completed, which list the capabilities, UIs, and other significant components.

Stages (Phases) of System Development Life Cycle

The project manager is responsible for executing and closing all the linear steps of planning, building, and maintaining the new or improved system throughout the process. The systems development life cycle originally consisted of five stages instead of seven. The typical stages of the system development life cycle are planning and 7 phases of system development life cycle feasibility, requirements analysis, design and prototyping, software development, system testing, implementation, 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. The seventh and final stage of the software development lifecycle is comprised of regular updates and adjustments based on real-world performance feedback. The application’s capabilities are bolstered and refined to meet the needs of users. Based on the Business Specification document, senior development team members bring together the input of stakeholders and experts to plan out a software development project. The project may be focused on building a new software product or improving a current one.

Stage 5: Implement

In web development teams, a prototype often serves to show that the functionality works, although it will still need polishing. In IT, the term «life cycle» was first used in the 1950s and 1960s to describe the stages involved in developing a new computer system, but it is now commonly used to refer to all stages in the production of any type of software [1]. Team members can depart and be replaced rather smoothly because SDLCs include well-structured papers covering project goals and processes. 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. It must now be thoroughly tested to ensure that there are no issues and that the end-user experience is not harmed in any way.

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. A long-standing notion in the wide world of IT, a system development life cycle, or SDLC, is an iterative process that incorporates numerous activities that constitute the development of a structured information technology system. Since SDLCs have well-structured documents for project goals and methodologies, team members can leave and be replaced by new members relatively painlessly. Theoretically, this model helps teams to address small issues as they arise rather than missing them until later, more complex stages of a project.

Or contact us to find out how we can help with your custom software development project. To help mitigate the amount of maintenance that needs to be done, teams may choose to first release the product to a smaller population of customers. This can offer insight into how the product is performing and the development teams can make any last adjustments prior to its final release.

Software development life cycle (SDLC) is the term used in the software industry to describe the process for creating a new software product. Software developers use this as a guide to ensure software is produced with the lowest cost and highest possible quality in the shortest amount of time. The project manager is the overall control agent for a strong SDLC process. Following each phase of a system development life cycle the team and project manager may establish a baseline or milestones in the process.

In order to understand the concept of system development life cycle, we must first define a system. A system is any information technology component — hardware, software, or a combination of the two. Each system goes through a development life cycle from initial planning through to disposition. Systems analysis and design (SAD) can be considered a meta-development activity, which serves to set the stage and bound the problem. Architecture, and business architecture, and relies heavily on concepts such as partitioning, interfaces, personae and roles, and deployment/operational modeling to arrive at a high-level system description.

Famous for its iterative approach to software development that offers rapid-fire progress, Agile is a framework that fosters highly collaborative environments between all the teams involved in a project. Since then, it has contributed to building tons of successful software products. Many companies later adopted and adapted it to develop an effective process tailored to their needs. The SDLC, by its nature, was invented to save costs, build quality and complex software, and satisfy the end-user. A business analyst evaluates the business case and starts the logical design of the software by using the requirements and information collected by the product manager.

The primary goal of SDLC is to provide a clear structure to programming development teams so that they can operate efficiently, make informed judgments, and avoid overpaying. It includes everything from the beginning – such as deciding what the software should accomplish and how to the end of the project and how to maintain the software after it is created. Do you have an upcoming software development project or existing software that has reached its maintenance stage? An IT outsourcing partner can help you with the entire software development process. Time and again, it’s been proven that projects not only benefit but thrive by following a standardized set of steps to achieve a final result. Cue the Software Development Life Cycle which allows the team to work on manageable phases until the project is released.
