Earlier research suggests that public and private organisations have different reasons for organising in projects, and taking contextual factors into consideration is important in understanding project organising and management. This paper concerns how people involved in organising a project experience divergences in project organising norms and how those differences affects the organising process. The paper is based on a case study of a public sector project where four persons from the private sector have been recruited to a municipal project. From their perspective, I tell a story of how private sector project norms clash with public sector ways of organising.
