What agile method do you use? What agile methods are the most common?

Question

I am taking a software development class right now and we are discussing agile methodologies. What are the most common agile methods? I need to look into several and discuss their strengths and weaknesses. Seems more useful to look into the most prominent methods.

Observations:

Scrum seems pretty popular (that is what my team used on two of my coops).

Extreme also seems to get quite a bit of buzz but I am not sure if that many people actually use it.

What does your company use and how do you like it? Does anyone use:

• Agile Modeling
• Agile unified process
• DSDM
• Essential Unified Process
• Feature Driven Development
• Open unified processes
• Rational Unified Process

Are there other methodologies that I should investigate?

Answer 1

I've used SCRUM in personal projects with friends and schoolmates and my current employer uses a custom agile process that's very similar to SCRUM but with fewer meetings.

Answer 2

We have used Test Driven Development and Scrum.

Answer 3

I've been on some very successful teams which used Scrum very effectively. It really does help to keep everybody focused and constantly moving forward, and it discourages regressions.
