A serious weakness in several organizations seems to be that numerous experiences are poorly reported. Unfortunately, there is little research conducted in the military field; on the contrary, there is an urgent need in several organizations to get a lessons learned process implemented. The aim of this paper is to compare group performances with individual performances and to determine whether groups will produce more mature experience-reports than individuals. The study was conducted within the Swedish Armed Forces; all participants were soldiers previously deployed on international missions. The results showed that groups produced somewhat better reports than individuals; however, individuals produced a higher quantity of reports per person than groups. It therefore appears to be pointless to report in groups, at least as was done in this study, since the extra effort it takes does not justify the small improvement.
