Software process implementation fails if adequate mutual understanding about the process model is missing. We are assuming that this happens because of differences and conflicts between the mental images of the process in question. We call this mental image subjective process conception of a process in case. In this paper, we introduce a method in order to elicit possible contradictions between subjective conceptions about the evolution state of a process. First we define an interview framework, which is based on The Basic Modelling Situation, The Process-Ontological Model and identification of five evolution qualities of a process. The dimensions of five qualities are defined. Then, based on the adopted framework we will present questions for a semi-structured interview which focus the interviewer on themes to be explored. Identification of contradictions and differences between process conceptions is based on simple measurement and visual presentation of data.
