It's one thing for a consultant to have great ideas that would help your clients. It's quite another to actually help those clients actually implement those ideas.
I've recently been interviewed by PM Boulevard about introducing agile methods. They asked me five questions:
Why use Agile methods?
What is the biggest challenge of implementing Agile methods?
In what environment will Agile be most successful?
What is the future of Agile?
What other information source about Agile do you find interesting or intriguing right now?
On the same site, you can also read answers to these same five questions by David Anderson and Steve McConnell. Check it out: PM Boulevard
