ERP implementation is a complex and expensive project for organisations because it touches upon social, behavioural and technical issues. This article presents an in-depth case study of an ERP consultancy in order to comprehensively understand ERP implementation from the consultancy’s perspective. Interviews were conducted with consultants, project managers, senior managers and other employees. The interview responses indicate that both the client and the consultancy measure success in terms of quantifiable units of time, cost and scope. In addition, qualitative measures of client maturity and client satisfaction are central to achieving project success for the consultancy when implementing ERP systems. Through incorporating critical success factors (CSFs) in the project methodology, the consultancy can ensure repeatable implementation processes, which contribute to a higher probability of success for both the consultancy and its clients. This study contributes by identifying consultancy CSFs: project management, IT environment, training and education, change management, and maintenance and support. Furthermore, the client’s maturity, and the management of client expectations are identified as unique CSFs for the ERP consultancy. This study will be beneficial for ERP consultancies, practitioners and researchers.
