On estimating the failure characteristics of extremely reliable units, field data of the units are very useful, but there exist some traps and difficulties to overcome in their observation and analysis. This paper points out five problems concerning the matter, and shows four methods to solve them under the extended models of failures and generalized ways of observations. Some make it possible to take into account various maintenance informations and to estimate the reliabilities, or mode-by-mode failure characteristics, from short interval observations of the units in a field.
