from the publisher's site: "The purpose of this paper is to investigate the nature of qualitative construction partnering research.
Design/methodology/approach. In total, 20 qualitative peer-reviewed papers about construction partnering research are reviewed.
Findings:


The results show four methodological gaps. All identified gaps have in common that specific time and place dependent details that may have influenced understanding of studied individuals are underexposed.
Research limitations/implications

The main limitation of this study is that empirical-based papers are divided into either qualitative or quantitative research, but the boundary between those categories is not as black and white as it may look like in first instance."
