In this research, a step by step approach is followed to find the root cause of the lagging adoption of an automated planning system by equipment planners. This is done by exploring the Technology Acceptance Model by Davis, from which a conceptual framework is established. This framework is central to a survey conducted under equipment planners globally. The results of this survey, and follow-up interviews, allow to identify the root cause of the lagging adoption of the new system. Furthermore, these results are used to draft a road map to improve the adoption rate.
