Agile is about people, both the people doing the work ("People and Interactions over Process and Tools") and the beneficiaries of the work ("Our highest priority is to satisfy the customer through early and continuous delivery...."). I believe people's own experience makes the most convincing arguments.
So I start by asking the people involved what has worked for them in the past. I ask them to remember their best projects and share the stories of those projects with other people in the room. (See Remembering Heaven for a description of how I do it). After hearing everyone's best projects and identifying the most promising role models for moving forward, we reflect on the patterns that made those projects successful.
Most people are not currently working on their best project ever. In fact, usually only about 10% of the people in the room are currently working on a great project. Very often no one at all is currently working on their best project ever. (I have seen numbers as high as 50%, but the difference between 10% and the higher score has always been a group doing Scrum!)
Would you like to be working now on your best project ever? Most people would! Could you agree to implement the patterns which made your best projects so awesome? Most people are willing to do that.
Wait! What exactly have we agreed to? Well at this point, I start to introduce Scrum (my favorite place to start), not as a set a of roles and processes, but rather as a small set of patterns. These patterns are easy to recognize in people's own successful projects. What patterns do we find?
- Deliver something that works regularly
- Inspect and Adapt regularly
- A small interdisciplinary team solves the problem
- Once voice speaks for the customer / user / stakeholders
- Management guides and helps, and knows when to stay out of the way
- High performance is achieved through continuous improvement
