🤔 The '5 Whys' Technique Introduction

The script begins with an introduction to the '5 Whys' technique, a method for exploring the root causes of a problem. The technique is popular in the field of design thinking and has its origins in the Toyota Production System from the 1980s. The speaker intends to delve deeper into the meaning of the '5 Whys' and to provide a simple method for the audience to understand and apply it effectively. An example involving a student who frequently arrives late to class is presented to illustrate the application of this method.

📊 Analyzing the Root Cause with '5 Whys'

This paragraph delves into the application of the '5 Whys' technique using the example of a student who is habitually late to class. The first 'why' reveals that the student wakes up late because they go to bed late. The script suggests visualizing this cause-and-effect relationship in a graph to better understand the situation. The speaker proposes to further investigate the deeper reasons behind the student's late bedtime, hinting at the need for a more detailed analysis and data collection to establish correlations and solve the problem.

10:12

🛌 Understanding the Impact of Course Load on Sleep Schedules

The script continues to explore the reasons behind the student's late rising by examining the impact of having multiple courses, which leads to a heavy workload and consequently affects the student's sleep schedule. The speaker suggests that reducing the number of courses the student is enrolled in could be a straightforward solution to help them arrive at class on time. The paragraph emphasizes the importance of considering the number of courses as a potential factor contributing to the student's tardiness and encourages further analysis to confirm this hypothesis.

📈 The Relationship Between Customer Visits and Business Income

The speaker shifts the focus to a business scenario, discussing the relationship between customer visits and the income of a friend's car workshop. By plotting the number of customer visits against income, the speaker identifies a clear correlation and suggests strategies to increase customer visits, such as offering free services to incentivize customers. The script also touches on the idea of expanding the workshop's reach by opening additional locations or collaborating with local mechanics to increase customer proximity and, consequently, income.

🚗 Addressing the Challenge of Customer Distance and Workshop Accessibility

The final paragraph addresses the challenge of customer distance and its impact on the workshop's income. The speaker proposes creative solutions such as offering pick-up and drop-off services for customers' vehicles, eliminating the need for customers to travel to the workshop. The script discusses the importance of considering both the customer's and the company's perspectives to find a mutually beneficial solution. It concludes by emphasizing the need to focus on reducing the distance customers must travel as a key factor in increasing both customer visits and business income.
