Action-research in a research and development laboratory at Xerox Palo Alto Reseach Center, California, USA. One researcher worked with a group of twelve engineers and physicists who wanted to investigate new types of computer support and reorganization of their work. The lab has sixty employees who develop high tech artefacts. The research goal was to learn and test ethnographic techniques, especially video based analysis. The project lasted two month full time.
