ODI was first commissioned in a partial or prototype configuration (pODI) using 13 OTAs in the summer of 2012, and was available for science observations since early 2013. pODI was decommissioned in late 2014 to undergo a significant upgrade. The upgraded ODI, now using 30 OTAs in a 5x6 layout was

The WIYN Consortium is governed by a board of directors, which includes three members of each partner institution. The board meets twice a year. The
Science Steering Committee provides scientific guidance to the board and the WIYN director.
