Abstract: The East Asian Observatory is currently releasing all SCUBA-2 850 μm data taken from 2011 to 2015, re-reduced in a uniform manner with automatically produced co-adds and catalogs. While the primary reason for doing this release was to produce a scientifically useful data product for our community, the process of creating it generated many benefits for the observatory itself. We have developed improved DR configurations, new and improved software and systems for running (and easily re-running) various automated pipeline reductions. We built into this a new quality assurance system now used for our nightly reductions. The analysis of the data prior to release helped us discover (and fix) some bugs and identify areas ripe for further investigation. This paper will describe these side benefits, and also discuss what attitudes and policies at the observatory ensured they occurred. The process has also helped the observatory gain a clearer understanding of exactly which pieces of information and metadata are most needed by external users. We can now use this information to improve our systems and our archive; thereby better supporting both our own, future data releases, and our community's use of the JCMT science archive.
