We spoke with Mr. Naoyuki Kiyota, a data scientist leading the Data Science Team in the DX Promotion Unit at TSUTAYA Co., Ltd., about why they introduced Repsona and how it’s working for them.

What kind of work do you use Repsona for?

Mr. Kiyota:
Our DX Promotion Unit focuses on marketing driven by customer data.

We design, develop, and operate data integrations using cloud servers; create and implement marketing automation (MA) scenarios; and design, develop, and manage APIs that link data with various applications.

We manage all of these as projects, and use Repsona for both task management and progress tracking across the team.

What challenges did you face before using Repsona?

Mr. Kiyota:
For a long time, we managed task sharing and planning within the team using Excel, but updating progress there became a major burden.

Many members couldn’t update their task statuses before regular meetings or progress reviews, and it was difficult to share updates—like task assignments or additions—with everyone at once.

When Excel files were stored in shared folders, it was hard for members to visualize and understand key information, such as who is responsible for what task and by when.
This often led to issues when handing over tasks or assigning new ones—some members ended up overloaded while others had too little work.

Updating Excel itself also took too much time, and I felt there were clear limitations to managing progress that way. We needed a tool that made entering, editing, and deleting tasks effortless.

With Repsona, every member can easily see who’s responsible for what and who currently “has the ball.”
That makes it much easier to discuss progress, improve efficiency, and update and share changes instantly with the whole team.

Clearly shows who’s responsible and who currently has the ball.

Why did you choose Repsona?

Mr. Kiyota:
The first reason was its ease of use. Compared to other tools, Repsona’s interface is much more intuitive, which keeps onboarding for new members very simple and lowers the barrier to adoption.

Another major advantage is how easily you can view the Gantt Chart (Timeline).
Being able to visualize plans on a time axis makes scheduling much clearer and more efficient.

In addition, it’s convenient to see the view by assignee or ball holder—you can immediately understand who’s responsible for what, and quickly check for uneven workloads or delayed progress during reviews.

I’m very satisfied overall. We plan to continue using Repsona for both team management and progress tracking.

Simple operation and easy-to-understand Gantt Chart (Timeline).

What do you expect from Repsona in the future?

Mr. Kiyota:
I look forward to even more feature improvements.
For example, it would be helpful if tasks could be listed in the order they were marked “Done,” or if we could selectively share notes with limited visibility.

I’d also like to see more examples and best practices of how other teams use Repsona—so we can make even better use of it within our own workflow.
