Policy implementation research in general and educational policy in particular is loosely connected to policy-making processes. There is a gap particularly in the field of vocational education. This often leads to conflicts and contradictions between policy-maker objectives and end-user implementation. To avoid such a disconnect, the relation between the world of end users and the world of decision-makers should be carefully constructed. This might be done through connecting the process of decision-making to implementation and carefully developing methods that encompass the demands of decision-makers and the needs and informational requirements of end users. Our intensive case study research on the process of a vocational education reform in the marine sector confirms that the lack of robust connection and active engagement of implementers as the end-users in the design of the policy created challenges for its implementation. Using a theoretical framework based on the notion of "boundary objects" we bring an alternative to current practice by creating the potential to illuminate and remove tensions and challenges for policy implementation. From there we infer that adopting this concept for policy design may prevent such conflicts and contradictions and result in successful implementation.
