Reviewers performing systematic literature reviews require understanding of the review process and of the knowledge domain. This paper presents an iterative approach for conducting systematic literature reviews that addresses the problems faced by reviewers who are novices in one or both levels of understanding. This approach is derived from traditional systematic literature reviews and based on observations from four systematic reviews performed in an academic setting. These reviews demonstrated the importance of defining iterations for the eight tasks of the review process. The iterative approach enables experiential learning from the two levels of understanding: the process level and the domain level.
