we are a small web development company that has till now been working on client projects. we employed little to no project management and that has cost us a lot. we've used only the barest of tools (wireframing, prototyping etc) but no formal project management process has been put into place.

we've learnt from our mistakes and want to prevent them from happening in the future. also, we are looking to develop our own products and we understand that putting in a proper project management paradigm will help.

after a lot of research, we've sort of settled on agile for a few reasons:

1. agile seems to scale well with team size. our team is small right now and we hope to grow and agile seems to be a process that we can put in place now and grow with.

2. agile will help us with customers who just can't seem to make up their minds and keep changing requirements.

we'd appreciate the community's thoughts on this. is this a correct way to think? will agile be a good system to put into place, where there has been none till now? are there any resources that may help us in our position?

pretty much all of the resources that we've found start by comparing agile to x (where x = any management methodology) and why its better than x and how agile can be implemented in place of x. we're looking for resources that can help us out in our particular situation.

thanks for all your help!
