Using Task Clarification, Graphic Feedback, and Verbal Feedback to Increase Closing‐task Completion in a Privately Owned Restaurant

An informant functional assessment was used to evaluate closing-task completion by servers and dishwashers at a restaurant. Based on the functional assessment results, an intervention consisting of task clarification, posted graphic feedback, and verbal feedback was implemented and evaluated with a multiple baseline design across two groups of employees. Results showed an increase of 15% and 38% in task completion for the two groups.
