The importance of generalized quantum measurements in quantum optics and precision measurements is indicated. These measurements are formally realizable within conventional quantum mechanics and can often be interpreted as approximate simultaneous measurements of noncommuting observables. An uncertainty relation more stringent than the usual one is derived for these measurements.
