MDP is a workshop about the interrelation of modeldriven development (MDD) and development processes. The workshop provides a forum for researchers and practitioners to exchange experiences on the questions how processes need to adapt or can be adapted when model-driven techniques are applied. We argue that the interrelation between MDD and development processes can be crucial for the success of MDD. For example, the need to adapt a process when introducing MDD can be a reason to decide against an MDD adoption. Further, we aim to give an introduction to foundations and research perspectives. MDP is co-located with ACM/IEEE 17th International Conference on Model Driven Engineering Languages & Systems.
