Inspections have become integral part of the software development. The inspection process has many attributes that are easy to measure. Companies use these measurements as part of controlling and planning instruments. To improve review techniques, researchers are experimenting with attributes. This paper describes an analysis of industrial historical data. The nonparametric Mann-Whitney statistical method has been used to test number of hypotheses. Firstly it has been demonstrated that slower reading during preparation leads to higher Defect Rate. Secondly the experiment with number of reviewers in the group has been replicated. Previous studies have shown effectiveness of small teams in controlled conditions but we have proved its validity in the industry as a whole. Finally we have confirmed the value of industrial metrics and prepared basis for the controlled experiment in the industry.
