Question

First of all I thank everyone who spend your valuable time here to answer my question . what are the software development methodologies ? I heard the word agile and what are the other methodologies and which is best and new?

Answer 1

Each has its pros and cons.

Agile methodologies follow the agile manifesto:

http://www.agilemanifesto.org/

They focus on fast software releases and customer satisfaction, and tend to not give much importance to requirements engineering and documentation.

Some examples:

XP - https://en.wikipedia.org/wiki/Extreme_programming

SCRUM - https://en.wikipedia.org/wiki/Scrum_(software_development)

You can run XP with a team of about 13 members. SCRUM can be run with 5 to 7 members.

On the other hand there are traditional methodologies, one of the most famous being RUP (Rational Unified Process). This methodology requires a large team. Focus on traceability and documentation. It's generally recommended for critical and large software. Ex: the software that runs an airbus, or controls a self driving car, or a big software like microsoft excel, etc.
