The aim of this workshop was to discuss how to implement more flexible operating models for joint or target of opportunity observations of multi-messenger events. While several obstacles exist that prevent far reaching standardisation of software and infrastructure for facilitating such coordination, several recommendations were made that could improve the opportunities for joint observations and follow-ups in the future. These include the idea that observatories, facilities and scientists need to agree upon what data can be shared and to also publicise their observing schedules, there is a continuation of the standardisation of communication protocols for transient and multi-messenger events, that new software implementations for coordinating joint observing between facilities be open source, and that the multi-messenger community become actively involved in the making of observatory transient policy.
