Sharing and optimizing operations and resources between Maunakea Observatories

The eight Maunakea Observatories continue to excel and expand but have traditionally been isolated facilities despite their close proximity to each other, with little formal sharing of human or technical resources. This has been changing recently, led by multi-telescope observing time swaps, budget challenges and the shared security pressures of Maunakea summit operations. Over the past two years, a series of Maunakea Operations and Engineering workshops have been held, discussing shared issues and novel ways of resource lending and sharing. The ideas and implementation of the first operations sharing initiatives that resulted will be presented, along with the lessons learned by reviewing the shared experiences of this wide range of highly productive facilities.
