Task $3.$ Given these insights, create a fishbone diagram that encapsulates all these potential causes leading to the problem of picking wrong items.

Continuing the investigation into the high rate of picking errors at OptiTech Distribution Center, the specialized team tasked with identifying the root causes of these errors has moved into the next phase of their analysis. After developing a fishbone diagram to visually organize potential factors contributing to the problem, the team decided to further explore the impact of picker experience on error rates. This decision was informed by the fishbone diagram's insights, which suggested that human factors, particularly experience, could be a significant contributor to the problem.

To quantify and test this hypothesis, the team compiled performance data for $40$ pickers. The dataset includes the total number of picking tasks each picker had completectoefore this month compared against the number of errors they made during the current month. This approach aims to establish whether there is a definitive relationship between a picker's experience and their likelihood of making errors.
