For successful, continued, operation of space-based instruments over the lifetime of a satellite it is common practice to put into place procedures to identify, investigate and monitor long term trends in the characteristic parameters of an instrument in order to be able to take action before a failure of the instrument or a subsystem occurs. With the advent of more sophisticated instrumentation and the need for efficient utilization of ground-based telescopes, there is an increasing need to carry out this function as part of the routine operations of ground based observatories. This paper characterizes the types of trend data that may be obtained during the lifetime of an instrument and presents examples of such data taken from the long wavelength spectrometer instrument on-board the IR space observatory. The resulting actions taken to minimize the possibility of failure of subsystems and to maximize the scientific output from the instrument will be discussed.
