Interorganisational or chain information systems have become a frequent subject of scientific research, but not often an empirical perspective on these systems is taken. In this study we develop a model for measuring the chain digitisation maturity of organisations and validate it by conducting a survey among 33 CIOs. In addition, one of the responses is further investigated through a case study. Based on the survey data, three determinants, namely (i) complexity of chain digitisation solutions, (ii) synchronisation of data and (iii) the size of the organisation, appear to be correlated with chain digitisation maturity. This is confirmed by the case study, which also provides a deeper understanding of alignment of technology and organisation on the one hand, and the supply and demand chain partners on the other. We conclude that the topic of chain digitisation alignment deserves further research, as does its situationality for profit and non-profit organisations.
