In many industries structural change through E-Commerce is challenging firms to re-align their strategies as well as re-engineer their business processes with new competitive environments while taking advantage
of technological opportunities. This article presents E-MEMO, a method for multi-perspective enterprise modelling with special emphasis on processes and technologies for E-Commerce. It serves to analyse and design corporate information systems that are balanced with a company’s E-Commerce strategy and its organisation. E-MEMO offers specific languages for modelling strategies, business processes, and related resources. In addition to that, it provides a library of reference models including strategy networks to guide strategic planning and models of business processes. In order to further support the implementation of information systems a transformation has been defined that allows for generating workflow schemata from business process models. Since design-oriented research is not predominant in the Information Systems field, the epistemological challenges of the chosen research approach are discussed, too.
