This article aims to contribute to a better understanding of how to integrate customerswithinservicedevelopment by assessing different methods of obtaining use information. The article reviews and classifies methods for customerintegration and it also presents a new framework that suggests four modes of customerintegration in which data is classified either as insitu (data captured in a customer's use situation) or exsitu (data captured outside the use situation) and as either incontext or excontext. Context is defined as a resource constellation that is available for customers to enable value co-creation. Accordingly, incontext refers to methods in which the customer is in the actual use context and has access to various resources, while excontext refers to a situation in which the customer is outside the use context and, therefore, has no direct access to the resources.
