Computerized Task Analysis
ACM SIGCHI Bulletin
We developed an integrated computer-based procedure for conducting task analyses of the human-machine interface. The data base established with this task analysis methodology can be used by various system designers to answer questions at different levels (e.g., assessing individual keystrokes vs. overall mental workload levels) and as the system moves through the design stage. Our methodology is based upon the use of conventional task analysis procedures for data collection purposes but employs computer spreadsheet capabilities for analyzing and presenting these data.
