Interview with Arie van Bennekum, Agile Manifesto co-author, conducted by Mirosław Dabrowski (Dec. 2014). You had an opening talk on Agile here during 9th International PMI Poland Chapter Congress. How do you feel about the conference? Do you think PMI becomes more aligned with Agile principles? I think PMI will adapt, they are already in the process of adaptation. I think that someone was asking the question: is PMI waterfall? PRINCE2 used to be waterfall as well but now PRINCE2 can be perfectly adapted to work Agile, because PRINCE2 is about agreeing on how to work and working accordingly. And when you can work Agile, work accordingly – that’s fine. I think PMI will be the same because I think all the time, every project we do, like Virginia’s talk about BIG DIG this morning, it has a lot of Agile in this mega, 20, 40 or even 60 billion dollar project. There is a lot of Agile, because these days we talk about complex solutions and I have three steps: from simple, through complicated to complex. Complex means there are a lot of different factors and the outcome cannot be predicted… And I think that's what life is all about these days. Giving technology, politics environment, education, people, marketing, there are so many factors in there that the outcome is not predictable. So you have to be able to adapt, and that’s what Agile is.
