Product usability has been subjected to many evaluation techniques. Many evaluation techniques use heuristics approach to evaluate the overall usability of the product. Considering heuristics works in some particular examples, In the healthcare sector, heuristics approach is hard to implement due to fundamental constraints (stakeholders, safety, and time requirements). This paper examines a scheduling algorithm that correlates to usability problem. The scheduling algorithm has a definite impact on the product Return of investment and customer satisfaction.
