We present a systemic modeling method to identify and categorize stakeholders within value networks, to analyze the relationships between these value networks and to infer IT requirements from this analysis. We illustrate the approach with an association who needs a web site. Thanks to this method, requirements that closely support the business strategy can be identified.value networkvalue systemvalue chainstrategic thinkingtext::report
