After successful commissioning observations, IGRINS will soon begin its normal scientific operations on the 2.7m Harlan J. Smith telescope at the McDonald Observatory. We will present a working version of the IGRINS operation plan. A fraction of IGRINS guaranteed time will be devoted to a selection of strategic programs with legacy values, whereas the rest of the time will be used for normal programs. We will also describe the current status of the IGRINS data reduction pipeline package and its future development plan.
