First published on: 23 September 2010 (iFirst). The aim of the research is to investigate the impact of software developers' performance in the software review process. A theoretical explicit and implicit input-process-output knowledge model was developed to analyse the important relationships among software developers' performance in software review process. A total of 1380 companies were invited to participate in this research and a total of 205 responses were used for final data analysis. The results suggest that software developers' experiences are the key driver for the software review performance. However, the use of explicit documents has no impact on software review performance. The new findings also suggest that the most critical factor in the software review process is 'teamwork', which can be affected by the characteristics of task, use of software documents and software developers' motivation.
