Task uncertainty and the use of computer technology

The relationship between task uncertainty and the utilization of computer technology was studied for a sample of 216 middle managers and first line supervisors in a large mid-Western bank. Greater task variability in Perrow’s technology grid was associated with the use of a greater variety of computing tools. Task analyzability was related to the type of computer application used. Where tasks were less analyzable, users opted for personal computers, mostly for analysis and inquiry applications. For more analyzable tasks, mainframe computers were used more extensively, mostly for exception and monitoring applications. Implications are drawn for future research on the use of computer technology.
