R3 Institute Ltd. (Headquarters: Osaka City, Osaka; President & CEO: Ken Nishimatsu) has published a case study on business improvement at Tokyu Livable Co., Ltd. (Headquarters: Shibuya-ku, Tokyo) through its business improvement and system development service "Kimino Mahoro for kintone."
This case study introduces the initiative of migrating complex Excel spreadsheets used for calculating real estate sale guarantee amounts to a kintone app, creating a system that allows sales representatives to instantly calculate estimates on-site. While the number of review requests approximately doubled, the working hours of the Sales Promotion Division, which handles the subsequent processes, did not increase, demonstrating simultaneous improvement in workload and processing efficiency.
The case study also reveals the behind-the-scenes development of dismantling complex Excel to build a highly accurate kintone app, along with real feedback from on-site staff.

■ Background and Challenges
Tokyu Livable's "Sale Guarantee" service supports customers during property exchanges by guaranteeing to purchase the property at a guaranteed price if it does not sell within a certain period, allowing them to proceed with their exchange plans with peace of mind. While this is an important service that differentiates the company from competitors, the number of review requests was stagnating.
There were two main reasons for this stagnation. First, the complexity of the review process. Sales representatives created review documents in Excel and submitted them to the Sales Promotion Division, with the entire process taking an average of 5 days until approval. Second, the low accuracy of simulations. Excel formulas sometimes deviated from market prices by more than 10%, making it difficult for sales representatives to trust the calculation results.
To solve these issues, there was a need to build a system that would allow sales representatives to instantly determine whether they should propose a sale guarantee.
■ "Sale Guarantee Amount Simple Simulator" Developed with "Kimino Mahoro for kintone"
R3 Institute developed the "Sale Guarantee Amount Simple Simulator" using kintone through "Kimino Mahoro for kintone."
- Instantly calculates the sale guarantee amount by simply inputting the property type (land, house, condominium), appraised value, total floor area, etc.
- Implements calculation logic based on multiple conditions such as internal standards and estimated renovation costs, achieving estimates close to market values.
- If a review is desired after calculation, it automatically outputs a "Sale Guarantee Application Review Form" as a PDF based on the input data.
Improving calculation accuracy started with analyzing each Excel formula to identify the causes of deviation from market prices. Specific design innovations and points for reviewing the operational flow of subsequent processes are explained in detail on the case study page.

■ Results of Implementation
The implementation of the simulator has yielded the following results:
- Number of review requests: 59 (before implementation) → 93 (first half after implementation), with a projected year-end total of 110, approximately a 2x increase.
- Number of sale guarantee amount calculations: Over 200 (no calculation function before implementation).
- Working hours for subsequent processes: No increase despite the doubling of requests.
A staff member from the Sales Promotion Division commented, "By making it an app, input errors have dramatically decreased. The system now automatically inputs dates and days of the week, which has also increased processing speed. Although the number of requests has roughly doubled compared to before, I don't feel like my working hours have increased."
Regarding the overall development, the company stated, "When you consult them with a 'let's just ask' attitude, they take what you say and expand on it, returning proposals with added value. They are like a go-to place for business improvement."
