Evaluation of engineers' public speaking using work sampling technique

Taking cognizance of the terminology and thought process more likely to be effective with a target audience of engineers, an effort was made to integrate the technique of work sampling with public speaking in order to ensure greater appreciation among engineers for concepts related to communication. In this study, the work sampling was employed to determine productive and unproductive percentages of onstage public-speaking time. A total of 1430 observations were taken from 55 engineers with an accuracy of ±5%. Average individual accuracy was found to be ranging from 1.09% to 2.96% while over accuracy was found to be 2.5%. The results indicated that the sample of engineers spent an average of 62.03% time in unproductive activities out of the given 120 seconds. While cases of improvements are presented, the study also deliberates on the details of the 62.03% unproductive time.
