Agility is a major concern for industries across manufacturing and service sectors for a variety of reasons. For instance, frequent product development to meet evolving customer requirements and changing markets requires efficient and agile processes. Therefore, companies need to capitalize on product and service development and ramp-up projects in order to improve their efficiency as well as time-to-market. This paper provides preliminary results to address this gap by proposing a model covering conceptual underpinnings of agile ramp-up management. The model is developed iteratively following the design science research methodology. A simple excel prototype resulting from the model is developed in order to support agile ramp-up project planning. The model as well as the prototype are expected to help decision makers in scoping ramp-up projects and in improving the consistency of these projects planning. They also support the collaboration within ramp-up project team through sharing a common understanding of the project scope.
