Software inspection is a method to detect faults in the early phases of the software life cycle. In order to estimate the number of faults not found, capture-recapture was introduced for software inspections in 1992 to estimate remaining faults after an inspection. Since then, several papers have been written in the area, concerning the basic theory, evaluation of models and application of the method. This paper summarizes the work made in capture-recapture for software inspections during these years. Furthermore, and more importantly, the contribution of the papers are classified as theory, evaluation or application, in order to analyse the performed research as well as to highlight the areas of research that need further work. It is concluded that (1) most of the basic theory is investigated within biostatistics, (2) most software engineering research is performed on evaluation, a majority ending up in recommendation of the Mh-JK model, and (3) there is a need for application experiences. In order to support the application, an inspection process is presented with decision points based on capture-recapture estimates.
