In your point of view what is the Software Development life cycle that you can use in your software environment?

I prefer  Agile Scrum because of the following benefits:

1. Customer satisfaction by rapid, continuous delivery of useful software.
2. People and interactions are emphasized rather than process and tools. Customers, developers and testers constantly interact with each other.
3. Working software is delivered frequently (weeks rather than months).
4. Face-to-face conversation is the best form of communication.
5. Close, daily cooperation between business people and developers.
6. Continuous attention to technical excellence and good design.
7. Regular adaptation to changing circumstances.
8. Even late changes in requirements are welcomed
