Information system adaptation and business process change pose specific issues. Based on our experience in the industrial context, we propose a methodological framework to tackle these issues. Among the lessons learned from the experimentation of this framework, the need to formally connect the different models used was identified. The approach presented in this paper advocates the use of a link meta-model to define this connection. Combined with business goal modelling and analysis of the gaps between models of the current and future situations, the link meta-model helps guiding the analysis of business process change for information system adaptation. The link meta model is applied with the case study of an evolving Pizzeria company.
