Background of 'Jin-sen-san' App Development
In business and project settings, coordination tasks such as 'who will handle what' and 'in what order will we proceed' occur daily. Often, however, these tasks are time-consuming and can lead to bias in the decision-making process. Particularly in teams with high turnover or organizations operating across multiple locations and departments, these repeated coordination tasks have become a burden on the staff.
To solve these issues, 'Jin-sen-san' was developed as an app that allows anyone to easily and fairly conduct personnel selection and sequence determination within LINE WORKS talk rooms.
App Overview
'Jin-sen-san' is an app that allows users to randomly perform grouping, sequence determination, and lottery (assigning responsibilities) for members participating in a LINE WORKS talk room.
Users can confirm results immediately just by selecting the conditions and share them directly within the talk room, eliminating the need to transcribe results for sharing.
Main Use Cases
- Deciding the order of presentations or moderators for meetings and morning assemblies.
- Dividing members into groups or teams for training and events.
- Assigning business duties such as cleaning duty, meeting minute recorders, or reception shifts.
- Selecting personnel for organizational and community management, such as PTA, club activities, and event management.
*It can be used in various organizations and group activities, not limited to business scenarios.
Main Features
- Grouping:
Randomly divides members within a talk room into a specified number of groups (2 to 10). After displaying the results, it is also possible to create talk rooms for each group if necessary.
- Sequence Determination:
Randomly reorders members within a talk room and displays the sequence with numbers. It can be used for deciding presentation order, work order, or duty rotation.
- Lottery (Assigning Responsibilities):
Randomly selects a specified number of people (1 to 10) from the members in a talk room. It can be used for deciding who is in charge of tasks or duties.
*The above features can be used in talk rooms with 2 to 100 participants.
Usage Fees
This application can be used for free, regardless of your subscription plan.

About 'LINE WORKS'
LINE WORKS is a business chat tool equipped with comprehensive groupware functions useful for daily operations, including chat, stickers, bulletin boards, calendars, address books, and surveys. It is developed and provided based on the usability of the communication app 'LINE,' allowing anyone to use it immediately from the day of introduction with minimal training. Because most functions can be used on smartphones alone, as well as on PCs and tablets, its adoption is progressing not only in office work but also in 'field' settings such as bases and stores where PC usage time is limited. There are free and paid versions (Standard/Advanced). Most basic functions can be used even for free, and it can also be used for interactions with external parties such as customers and business partners.
According to the 'Software Business New Market 2018-2025 Edition' by Fuji Chimera Research Institute, it has held the No. 1 domestic share of paid business chat for eight consecutive years from fiscal 2017 to fiscal 2024.
