Document Summary

Improvements in human-computer interaction-> reduced task performance time, key strokes and number of errors. Improvements in manufacturing plant-> reduced injury, inc productivity, inc quality, inc workers comfort. Cost efficiency of improvements: benefit/cost ratio for the first yr of application. Scientific point of view, the study was unsatisfactory- no control group to compare results, cud be b/c of uncontrolled factors like changes in management b/c unrecorded. patterns between employees. Structured, symbolic format for the results appearing on the display- impact time performance. Usability important factor that assessments of computer systems/softwares often disregard= satisfied users and work flow more interesting than difficult.
