Toridoll Holdings' first management book introduces its joint initiative with XICA.

In the media

Using data science, we scientifically examine the relationship between employee "happiness," customer "excitement," and store "success."

As a partner that supports diverse management agendas with data science, we back up "psychological capital management."

XICA Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Yoshiaki Hirao; hereinafter referred to as XICA), a provider of data science-based marketing and management support solutions, is pleased to announce that practical examples of data science initiatives jointly undertaken by Toridoll Holdings Co., Ltd. (hereinafter referred to as Toridoll HD) and XICA have been featured in the new book "Toridoll's Leap Forward: A Contrarian Winning Method Starting with an Employee-Focused Approach" (Nikkei BP), written by Takaya Awata, President and CEO of Toridoll HD.

This book details the advanced data analysis models and methods that Toridoll Holdings has jointly developed and verified with XICA, providing scientific backing for its "psychological capital management" philosophy (a management philosophy that aims for sustainable business growth by creating "emotional happiness" for employees and "emotional inspiration" for customers).

Background and key points of the initiatives introduced in this book

Toridoll Holdings advocates the "Happy-Con Prosperity Cycle," which posits that increased employee happiness (EX: Employee Experience) leads to a deeper customer experience (CX: Customer Experience), ultimately resulting in store prosperity (improved business performance). To scientifically verify the effectiveness of this hypothesis, the company has been utilizing data science since 2018. XICA is a partner in this effort, jointly promoting data analysis and verification.

1. Statistical modeling to verify that employee "happiness" influences "performance."

Through joint development with Toridoll HD, XICA is building and verifying an algorithm that analyzes and visualizes how the "Happiness Score (EX)," which scores employee psychological elements (four elements: "sense of security," "sense of connection," "sense of contribution," and "pride"), influences business results (business success) such as customer numbers and sales, via the "Customer Satisfaction Score (CX)." Data analysis has confirmed that improving employee happiness increases the customer satisfaction score, which ultimately has a positive impact on business performance (sales and customer numbers).

2. Predict sales revenue from "Happiness Score" and "Emotion Score"

Toridoll Holdings and XICA are working on building an algorithm that estimates and predicts future sales increases (impact on performance) based on Happiness Score (EX) and Customer Satisfaction Score (CX) data. This will enable them to predict future sales impacts according to the status of each store's Happiness Score and Customer Satisfaction Score, and to formulate specific actions and management strategies tailored to the problem factors with high reproducibility using data science.

XICA's role and future prospects

XICA has worked closely with Toridoll HD, closely adhering to their management policies, and has acted as a "partner providing scientific backing" by structuring and analyzing them as objective and highly reproducible data.

XICA has supported corporate decision-making primarily through solutions that visualize marketing from both qualitative and quantitative perspectives, including Marketing Mix Modeling (MMM). This latest initiative visualizes the relationship between the qualitative value of employee well-being and business performance, demonstrating how data science support is expanding beyond the marketing domain to encompass overall business management.

XICA will continue to support companies in solving various important management agendas related to their sustainable growth, based on data science.

Comments from representatives of both companies

Takaya Awata, President and CEO of Toridoll Holdings Corporation

We believe that the foundation of a company's sustainable growth lies in the happiness of its employees. When each individual feels happy and takes pride in their work, that happiness creates customer satisfaction, which in turn leads to the company's growth. In this book, I share the philosophy and initiatives of "psychological capital management" that the Toridoll Group has practiced, incorporating my own experiences.
We have been working closely with XICA Co., Ltd. on this initiative to scientifically analyze and verify our management strategy using "data science." It is because we have solid data to back up our efforts that we can confidently promote our psychological capital management.

Yoshiaki Hirao, President and CEO, XICA Co., Ltd.

We are deeply honored to have been a long-standing partner of Toridoll Holdings in their innovative initiative of "psychological capital management," leveraging data science. Since its founding, XICA has used the power of data science to unravel areas that are considered difficult to quantify, supporting marketing and management decision-making. We believe that our ability to scientifically visualize how the qualitative value of employees' "sense of happiness" generates customer "excitement" and leads to business results is a symbolic initiative that demonstrates the new possibilities of data science. As labor shortages become more serious in many industries, we believe that the importance of management that balances employee happiness and business growth will only increase in the future.
