In today's world developing complex projects is becoming more and more challenging. I am a strong believer that switching to Agile is the right move to help deal with these challenges, But the question is "How?" Doing the transition too dramatically may actually create the negative effect, and in order to change many years of corporate culture and we need to focus on working with the managers to do this. In this talk i will present based on my own experience several tips on how an architect can assist in Agile transition by influencing the relevant managers.
