This paper apply personas to explore and analyze the highly regulated and (seemingly) uniform work practice of police officers. Historically, many information systems and information technology applications for the police has failed to meet the requirements of officers working in the field. It is claimed that a richer understanding of the practice outside the police station can result in more successful implementations of information systems for the police. An analysis of police practice is conducted through four personas of officers. The personas are derived through an analysis of an extensive set of qualitative data data from both police experience, and from observations and interviews. The personas are then situated in scenarios to visualize information related problems in the practice. The paper conclude that persona is a useful technique to analyze police work for design purpose.
