[Case Study] Realizing Efficient Internal Training with Ondoku - Juchheim Co., Ltd.


  • Juchheim Co., Ltd.
  • Scale: 101–500 people
  • Industry: Manufacturing and Sales
  • Interview: Ozono

Objectives/Challenges

Hiring many temporary part-time workers toward the end of the year. Onboarding education was conducted manually using a 40-minute PowerPoint presentation, but the repetition of the same content was labor-intensive, and the quality of explanations varied depending on the person in charge.

We tried to use audio recorded by employees for narration, but when actually recorded, it was difficult to hear and unclear.

Solution

By introducing Ondoku, we aim to improve the efficiency and quality of onboarding education by switching from manual PowerPoint explanations to automated onboarding education via video.

Results

Created onboarding videos using Ondoku narration, improving time and effort (reduction of 1,600 minutes per year: 40 times/year × 40 minutes). Additionally, explanations became more accurate and comprehensive than manual explanations, leading to improved quality.

Introduction of the Company and Department

Juchheim Co., Ltd. is a manufacturer and seller of Western confectionery, including Baumkuchen, based in Anjo City, Aichi Prefecture.

With approximately 400 employees, the company is loved by many customers as a community-rooted business.

The department that introduced the service handles general factory affairs, such as factory recruitment and payroll.

This time, we spoke with Ozono about the background, process, and effects of introducing Ondoku to the company's General Affairs Department.

Juchheim Co., Ltd.

Please tell us about the background behind introducing the text-to-speech tool.

At Juchheim Co., Ltd., we hire many temporary part-time workers toward the end of the year.

We provide onboarding education for these temporary staff. However, the current situation was that this onboarding education required significant time, effort, and cost.

Previously, onboarding education was conducted manually using a 40-minute PowerPoint presentation. The challenges were the labor-intensive repetition of the same content and the variation in explanation quality depending on the person in charge.

Could you tell us how you came to introduce Ondoku?

Facing these challenges, I researched on social media to try and automate narration creation.

That's when I discovered Ondoku.

Compared to other tools, I felt it was easy to use as I could understand how to use it immediately upon seeing it.

Its convenience as an automated narration creation tool and its ease of use were the deciding factors for its introduction.

Have your company's challenges been resolved (improved) compared to before introducing Ondoku?

After introduction, a time saving of approximately 1,600 minutes per year was achieved.

(Annual onboarding frequency: 40 times × 40 minutes = 1,600 minutes saved)

Additionally, automated narration standardized the quality of explanations, enabling accurate information delivery without omissions.

The usability of Ondoku is also very clear and easy to use.

Looking ahead, what selling points would you mention when recommending Ondoku to others?

I would recommend Ondoku by highlighting its ease of use as a key selling point.

Summary: Transformation through Ondoku

The case of introducing Ondoku at Juchheim Co., Ltd. serves as a very helpful example of efficiency and quality improvement.

Thank you very much for sharing this wonderful case study of how utilizing new technology can significantly reduce time and effort while improving the quality of education.

May this case study provide great hints for other companies facing similar challenges!
