1. Not focusing on Culture
Adopting Agile at an organizational level is something that will take a long time, bring about change throughout every level of the organization, face many difficulties, and require a great deal of experimentation and learning. In order for all of these to be possible it is not enough for an organization to simply adopt the practices of one of the many Agile frameworks that are currently available. This will lead to (maybe) some short term successes and some initial enthusiasm, but it will not setup the organization to sustain their Agile adoption over the long term. In order to really get a transformation to stick, the entire organization must experience a cultural shift that will encourage, support, and enable a focus on learning, failing, inspection, adaption, and continuous improvement. With the right culture in place, it will not matter what frameworks or practices the organization tries to adopt because they will be comfortable with trying many different things, continuing to focus on improving, and sustaining improvements over the long term.
