The software development life cycle is the process through which software is created. This process includes several stages, from the initial idea to the final product launch. Some common stages of the software development life cycle include:

• Problem analysis: In this stage, the problem being addressed by the software is determined and the scope of the project is defined.

• Design: In this stage, a detailed plan for how the problem will be solved is created.

• Implementation: In this stage, the software is coded and tested to ensure it works correctly.

• Testing: In this stage, thorough testing is performed to ensure the software works correctly and meets established requirements.

• Launch: In this stage, the software is released to the market.

• Maintenance: Once the software has been released, it is important to continue maintaining and updating it to ensure it continues to work correctly and meets the needs of users.

It is important to note that the software development life cycle does not always follow a linear order and it may be necessary to go back to earlier stages if problems or additional needs are found as the project progresses. Additionally, there are many different methodologies for software development, each with its own unique approach to the software development life cycle.
