Yes, there are process models that are entirely activity based, and some that are entirely about state change and world state goals/conditions/effects. This is an argument that has gone round the AI planning community for over 20 years too. There are planners based on either one of the extremes... and it can be shown that you can transform one to another with work and a certain perverseness in modeling approach. In reality most people mix the two - occasionally finding it convenient to model them at one extreme or another. Going for one rather than the other will definite be wrong for a large part of the community we want to serve. And not have longevity.
