It seems most companies are practicing Agile methodologies these days for software development. I'm curious to know if there are any downsides to using Agile, does it have shortcomings, is it always the right methodology to use? Do you any of you have experiences of using Agile and it didn't really work, maybe it was due to the type of project, or the team?
Are there any disadvantages to using the Agile methodology?

Agile is successful if you have an organization that is committed to doing it right.  No methodology will work if you don't have commitment and training in the methodology.I would also say that agile works best at a certain scale.  You have to be able to divide your project into reasonable size deliverables.  You wouldn't be able to build an office building or a nuclear submarine using agile.  Similarly, in software, some projects are large and complex enough that you really can't start without doing a lot of the up-front design work using a more waterfall-like approach.  Think about something like an operating system, for example.  Another example would be a system that crosses many organizational boundaries, like a national health electronic record system.Once you've done your overall architecture and design, you can use agile to build-out the features, but if you started with agile you probably wouldn't get off the ground.
