This article presents preliminary findings from a three year longitudinal study on the role of desktop computing in the work of 38 work groups that have integrated computing significantly into their work lives. Both quantitative and qualitative data were collected from surveys and interviews. End-users' participation in the process of implementing desktop computers in work groups is examined as a primary contributor to the quality of their work life, as is the available infrastructure (training, supplies, and consulting) to support computing in the work groups. Two primary implementation processes are examined: "top-down" and "grass-roots: We discuss the quality of work life of computer users along five dimensions: participation in decisions about work, job complexity, expertise and involvement in computing, changes in job enrichment attributed to desktop computing, and changes in work effort attributed to desktop computing. The quality of working life is most improved in work groups that computerize with grass-roots processes and have adequate infrastructure to support their work with computing.
