In many situations there is a need to integrate different methods. In such a method integration process learning aspects should be adressed explicitly. The paper presents procedure and experiences from a R&D project concerning integration of two change methods. Communication problems obstructed the integrative method redesign initially. These communication problems were resolved through the use of an explicit method theory for classification and reconstruction of the method candidates. During application of the integrated method further reconstruction of tacit method knowledge was performed. The method integration process also included meta learning: Formulation of the method integration as a learning process and modification of the applied method theory. Use of an explicit method theory/notion is important for learning methods. It should thus be included in methods training.
