Over the last year or so, our team embarked on moving from a typical Waterfall development approach to implementing a Scrum/Agile approach. While there are plenty of good blogs about making this transition from a development standpoint, I have not seen a lot of good information on what this change means from a business standpoint for an agency or professional services firm.
One of our biggest challenges is aligning the benefits of Agile to the way sales are accomplished in the organization. Our most effective sales approach has always been to have a fixed budget, fairly defined scope, and to provide timeline windows (X months, etc.).
