6. Concluding remarks
This paper presents a novel systematic process model for supporting future-oriented analyses of standardisation designed, in particular, for highly complex heterogeneous smart systems, where there are increased challenges of achieving interoperability between systems with different technological bases. The proposed process is intended to better support the effective organisation, management, and governance of standardisation roadmapping exercises, ensuring that appropriate attention is given to diverse stakeholder interests, as well as complex technology and policy considerations of smart systems. Based on public-level strategic roadmapping processes presented in existing literature, the process has been developed through the study of five major standardisation roadmapping exercises in various smart system domains. The case studies provide insights into the growing challenges and potential for system failures associated with complex standardisation efforts, particularly in emerging technologies with interdisciplinary systems nature, involving various stakeholders from different organisations and disciplines. The study also provides illustrative examples of specific activities and tools that may be effective in addressing these challenges, as highlighted in an in-depth case study of the NIST Framework and Roadmap for Smart Grid Interoperability Standards. Useful practices for addressing some of the organisational challenges of standardisation in smart systems include: gathering existing information for increased efficiency; establishing common definitions of fundamental concepts and developing system architectures at an early stage; and structured methods of use cases to identify standards gaps. Developing system architectures is found to be particularly useful in supporting stakeholder communications and strategic standardisation in complex, heterogeneous areas of smart systems. In addition, other policy implications are drawn out, including issues of participating stakeholders and important roles of government (particularly in areas where there are issues for national competitiveness, security, and societal infrastructure) in standardisation foresight exercises.
