What is SDLC? Software Development Lifecycle Explained


The deployment phase includes several tasks to move the latest build copy to the production environment, such as packaging, environment configuration, and installation. These are the approaches that can help you to deliver a specific software model with unique system development life cycle steps characteristics and features. Most developers and project managers opt for one of these 6 approaches. Now that you know the basic SDLC phases and why each of them is important, it’s time to dive into the core methodologies of the system development life cycle.

It then creates the software through the stages of analysis, planning, design, development, testing, and deployment. By anticipating costly mistakes like failing to ask the end-user or client for feedback, SLDC can eliminate redundant rework and after-the-fact fixes. SDLC works by lowering the cost of software development while simultaneously improving quality and shortening production time.

Iterative SDLC Model

More often than we’d like, these methodologies go forgotten or are not employed to their full extent. Other times, people get caught up in trying to decide which is the best software development methodology for their unique needs. The project overflows into the following stage when each phase is finished. In this phase of the Software Development Life Cycle, the product is made available to the users in the appropriate market. Product rollout is done in stages, depending on the company’s business plan. These design documents are designed to provide enough information about the software so that product designers may create it with minimum help.

An extension of the waterfall model, this SDLC methodology tests at each stage of development. 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, Design, Develop, Implement and Maintain.

Rapid application development (RAD)

Training usually covers operational training for support staff as well as end-user training. 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. This may involve training users, deploying hardware, and loading information from the prior system. CASE (Computer Aided Systems/Software Engineering) – organizes and controls the development of software or systems through use of a computer-assisted method.

Using CASE allows everyone to share a common view of the project and where it stands at each stage of development. Lean is about only working on what must be worked on at that specific moment. The project team is focused on finding opportunities to eliminate waste, to drop unnecessary things like meetings, and minimising documentation. The difference with the Agile approach in software is the focus on customer satisfaction throughout the entire lifespan of a system. As such, the move is done during off-peak hours, to ensure a minimal impact on business operations.

Stage 5: Test the product.

“Super users” can help in the training process to assist those with less technical experience and understanding. The training process should simulate actual use, and the team should not assume that users can learn on their own without assistance. This phase ends with a “go-live” decision and should include contingency plans to address challenges as the system is implemented.

At this step, desired features and operations are detailed, including screen layouts, business rules, process diagrams, pseudocode, and other deliverables. Conduct with a preliminary analysis, consider alternative https://www.globalcloudteam.com/ solutions, estimate costs and benefits, and submit a preliminary plan with recommendations. If you haven’t yet started your journey as a software developer, you might ask yourself, “Is software development for me?

Benefits of the Systems Development Life Cycle

The Software Development Life Cycle consists of seven main phases that any software system goes through. Keep in mind that all systems are different in terms of complexity, required components, and expected functionality. As the name suggests, the model divides the product into multiple stages and releases a functioning product in a short amount of time. Due to this, the consumer can view the end outcome and decide if he is happy with it or not.

  • SDLC or the Software Development Life Cycle is a process that produces software with the highest quality and lowest cost in the shortest time possible.
  • If the hardware part is available, the system includes the hardware part, and the development phase will include the configuration and adjustment of the hardware for specific requirements and functions.
  • Based on the response by the users, necessary enhancements are done after publishing it.
  • Many models of the development life cycle of information systems have been developed precisely on the basis of project management experience.
  • During any life cycle stage, more than one activity may also be carried out.

Integral to the success of any SDLC project, the developer writes project code and integrates system elements into a cohesive end product. Developers are responsible for developing the system architecture with assistance from the System Architect, evaluating and carefully selecting the right tech stack based on unique project needs. The Information System Architect is responsible for selecting the high-level tech stack and component structure of the future solution.

Test Driven Development (TDD)

The new seven phases of SDLC include planning, analysis, design, development, testing, implementation, and maintenance. It’s advantageous for large projects since development teams can create very customized products and incorporate any received feedback relatively early in the life cycle. Project managers in charge of SDLC need the right tools to help manage the entire process, provide visibility to key stakeholders, and create a central repository for documentation created during each phase. One such tool is Smartsheet, a work management and automation platform that enables enterprises and teams to work better. The project manager is the overall control agent for a strong SDLC process. Object-oriented analysis and design (OOAD) is the process of analyzing a problem domain to develop a conceptual model that can then be used to guide development.

During this phase, periodic technical support of the system is carried out to ensure that the system is not out of date. This includes replacing old equipment and continuously evaluating performance. This makes it possible to quickly and accurately describe all the necessary technical points.

System Development Life Cycle:

Empower your people to go above and beyond with a flexible platform designed to match the needs of your team — and adapt as those needs change. The final phase of the SDLC is to measure the effectiveness of the system and evaluate potential enhancements. 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.
