The recommendations have also been crafted to draw on the respective strengths of operational forecast centers and research scientists in the broader community. Considerable expertise in producing and disseminating forecasts exists at the operational centers. Therefore, Best Practices have been designed with their protocols in mind and they will play an integral role upgrading the building blocks of ISI forecast systems. In contrast, the research community is more focused on experimenting with novel ideas, approaches, and techniques. Their role involves expanding our understanding of ISI processes and the tools that are used to measure and simulate these processes. Communication and interaction between these groups will be critical to the improvement of ISI forecast systems.

Finally, the committee stresses that improvements to ISI forecasting systems and improvements in the use of ISI forecasts are possible. In particular, adoption of Best Practices offers a near-term way to aid forecast users and researchers by enhancing access and transparency to forecast information. Incorporating these practices will facilitate more frequent and valuable interaction among these groups. Over the coming years and decades, there are ample opportunities to improve the building blocks of ISI forecast systems and expand our ability to exploit the sources of variability. Although improvements are unlikely to be revolutionary, a coordinated effort by operational centers and the broader research community is likely to yield positive results over time.
