What is SDLC?
An organized procedure known as the Software Development Life Cycle (SDLC) provides the fastest possible production of high-quality, low-cost software. The main aim of SDLC is to produce top-notch software that meets and surpasses all client expectations and needs.
Overview of the process:
The client/business assesses the various project development components, including resource allocation, capacity planning, cost estimation, etc. Once everything is understood, they present the software team with the application's needs. The software team then creates an application blueprint and evaluates it to see if it adheres to the business requirements.
In some instances, they create a prototype to determine which among several options will work best. The application code must then be created and tested to make sure it is bug-free and meets the criteria.
Some software development projects come to an end when the application has undergone thorough testing. Many continue into the maintenance phase at the same time, though. The software team checks the application for bugs during this phase and makes the necessary adjustments to the program.

Learning the process in deep:
1. Planning
It is crucial to decide if and how to create your software project. Typical tasks in this phase include some of the following:
Budget for the project
Setting deadlines
Distributing resources etc.
2. Requirements
After the budget and capacity are decided in planning phase, business and IT teams collaborate during the requirements analysis phase to understand the business and technical needs of the finished product. Companies get into this stage knowing roughly what they want from their software. The end result is a comprehensive document that specifically defines all the needs in detail.
3. Design
Software architects and developers create designs for the finished software after outlining the requirements. These designs describe the application's visual appearance and internal workings.
4. Development
Development teams work with the design and an appropriate SDLC model to create the software application's necessary code. The goal here is to get the highest quality code and low runtime.
5. Testing
To verify that the software is of the highest caliber, testing teams run a variety of tests on the finished product. Automation and manual testing methods are used for quality assurance. If any bug was found, it is reported back to the development team and after getting it fixed, test teams come in to the picture again.
6. Deployment
After the testing is completed, the final product is launched to the users. This procedure is typically automated, allowing the development team to release stable versions as needed.
7. Maintenance
The software development process does not end yet even after launching.
The software team monitors the released version to see if it is performing as expected and if users report any bugs. All the problems are resolved in this stage and again go for testing before making it public to enhance the user experience.
