Abstract :
This paper proposes improving the usability of HTA (hierarchical task analysis) chart through redefinition. The plans in the existing HTA chart (HTAe) are replaced with symbols giving a proposed representation of HTA chart (HTAs). An empirical experiment was done on both types of chart, the HTAe and the HTAs, to see whether there is an improvement on the usability of HTA chart. An analysis was done on the score given for each task done correctly in interpreting the chart. An improvement was recorded. Lastly, a further redefinition of HTA chart was done based on results of the experiment carried out.
