What Is SDLC? Understand the Software Development Life Cycle



SDLC stands for Software Development Life Cycle, a structured software development approach involving a series of well-defined phases. It's a framework for software developers to plan, design, build, test, and deploy software applications within users' budgets. 


It also refers to a methodology with clearly defined processes for creating high-quality software. The software development cycle aims to produce superior software that meets and exceeds all customer expectations and demands to create a software application. It helps to reduce waste and increase the efficiency of the development process. It also ensures the project stays on track and remains a viable investment for the company.


Many companies will subdivide these steps into smaller units. Planning might be broken into technology research, marketing research, and a cost-benefit analysis. However, other steps can merge.


Software Development Life Cycle: From Plan To Product



1. Planning



The planning phase is the fundamental software development methodologies, regardless of size, terms, costs, etc. In this phase, the project leader evaluates the terms of the project, and cleaning defines the scope and purpose of the application. 


This aims to ensure that the development process and results would be smooth and top-quality. They plot the course, calculate labor & material costs, create a timetable, and get feedback from stakeholders before calling this phase done. It also keeps the project from expanding or shifting from its original purpose.



2. Define Requirements



The requirement phase is essential, where project members understand the client's final product with the team's help. They gather & analyze required materials and how they would go together. During this period, the team and the client would meet multiple times to outline each requirement in detail. It also helps minimize costs and boost the efficiency of the quality softwares.



3. Design & Prototyping



In the design phase, developers and architects define the technical details and high-level software system design to deliver each requirement. It seeks to develop detailed specifications that emphasize the physical solution to the users. 


They can include Screen Designs, databases, sketches, system interfaces, etc. They define not just the programming language but also methods of solving problems and performing tasks in the project.


Software Prototyping refers to building software applications, like one of the early versions of the software. It demonstrates a basic idea of how the end project would look and work.



4. Development



The development phase is the most delicate stage of all, which is a project management system process, like creating and building the project. The actual structured writing process enables the production of high-quality, low-cost software.  


Depending on the project size, this SDLC process would include the coding process. If the project is large, the tasks will be divided between team members accordingly.


The software development life cycle is frequently slowed by tasks like generating code to execute an application or waiting for test results, 's been crucial to identifying and correcting mistakes and malfunctions. SDLC would anticipate such delays, allowing developers to be assigned alternative tasks.



5. Testing 



Testing is done in this phase before the final assignment is revealed, whether the software succeeds or fails and works as the client wants. After testing, it can be ascertained that any mistake and how much you have done right can be redundant.

Software testers usually break down software testing into four categories:


  • Unit Testing - Small components of the software are tested one by one


  • Integration Testing - Multiple testers combine different software development models at once to test the software


  • System Testing - Testing the whole software


  • User Acceptance Testing - Clients use software components to determine whether the project meets their requirements.



6. Deployment



The deployment phase is when the software/project is released in the market and installed in the company. It seems the most specific task, and if you like paperwork, to ensure the deployment process, it is divided into various steps for convenience. 


It is known as the software development life cycle, where preparations, procedures, and ownership transfer processes are made. The tasks and activities are associated with specific deliverables depending on the nature of the project.


  • Preparations & Procedures - The team would install the software and do another few tests to ensure the success of the installation. It is essential to monitor that everything works as intended.


  • Product Deployment - The project team implements the programming and coding to each system location. 


  • Transferring of Ownership - The team transfers the ownership of the software to the client, who is now responsible for maintaining the system functionality.  


  • Closing the Deployment Phase: After the process, the team would confirm the results, update the completion dates and gather feedback.



7. Operation & Maintainance



The maintenance phase is when the product is provided upgrades, fixes, etc., after production. Monitoring the performance of the software is also included during the maintenance phase. As insurance, the development team set up a fixed time for new changes to ensure the final product after the product delivering. The consumers will not lose interest in the product as they "will upgrade the product soon anyway." 



Final Word


The Software Development Life Cycle (SDLC) is a structured software development approach involving a series of well-defined phases. SDLC phases ensure the software is developed efficiently, on time, within budget, and meets the user's requirements. Each phase of the development lifecycle has its own set of activities and deliverables, and each phase builds upon the previous oneIt's's essential to note that while the SDLC provides a structured approach to software development, it is not a one-size-fits-all process. Moreover, modern software development practices have evolved beyond the traditional SDLC model. Agile methodologies, DevOps, and continuous delivery practices have emerged to provide more flexible and iterative approaches to software development.
