Modelling methods provide structured guidance for performing complex modelling tasks including procedures to be performed, concepts to focus on, visual representations, tools and cooperation principles. Development of methods is an expensive process which usually involves many stakeholders and results in various method iterations. This paper aims at contributing to the field of method improvement by proposing a balanced scorecard based approach and reporting on experiences from developing and using it in the context of a method for information demand analysis. The main contributions of the paper are (1) a description of the process for developing a scorecard for method improvement, (2) the scorecard as such (as a tool) for improving a specific method, and (3) experiences from applying the scorecard in industrial settings.
