Commercially sensitive research poses a number of methodological challenges. These range from access to participants through to data rigour and reliability. Failure to address these challenges prior to data collection can lead to flawed research results and impact negatively on conclusions reached, theories propounded or policy recommendations developed. Despite the significance of these challenges, there is little consideration of them in current IS and management literature. Drawing on social science discussions of ‘sensitive’ research and the researchers own experiences of a commercially sensitive research domain, this paper provides insights on how to address the challenges of commercially sensitive research.
