Streamline Inc. (Headquarters: Shinagawa-ku, Tokyo; CEO: Yoji Kajiyama) has published a case study on the adoption of its IR material creation support service "LEAD" by Kitagawa Iron Works Co., Ltd.
By implementing this service, the company revamped its presentation materials for individual investors. This not only improved the design quality but also succeeded in significantly reducing the psychological burden on the person in charge of creating the materials.
Background to Outsourcing Material Creation and the Deciding Factor for Adoption
When holding its first company briefing for individual investors, Kitagawa Iron Works faced the challenge of wanting to better promote the company's appeal. Additionally, creating specialized materials in-house alongside regular duties was a significant psychological and man-hour burden for the person in charge.
While considering outsourcing to an external partner with expertise as a solution, the deciding factor for this adoption was confirming the extensive track record and high-quality design samples of the IR material creation support service "LEAD."
Effects of Adopting "LEAD"
Significant Reduction in the Psychological Burden of Material Creation
With a system in place to entrust everything from structure to design to professionals, the physical workload and psychological burden on the person in charge were reduced.
High-Quality Design that Embodied the Desired Image
The request for a "friendly and refreshing image" utilizing the corporate blue color was beautifully designed from a professional's perspective.
Accurate Output Completed Just by Conveying Correct Information
We were able to entrust the work with peace of mind as the output was accurately produced simply by conveying the correct information to the structure manager and designer.

Evaluation of the IR Material Creation Support Service "LEAD"
We received high praise for their supportive stance based on a fundamental understanding, which went beyond superficial work.
Proposed a near-final design from the first draft after just one meeting.
High level of content comprehension, with clever use of colors and presentation for slides that are difficult to explain.
Reliable project management with scheduling tailored to the desired delivery date.
[Comment from the person in charge]
"What is particularly noteworthy is that they brought it to a near-final state after just one meeting.
They carefully aligned the direction and proposed a high-quality design from the first draft. For slides that were difficult to explain, they devised clever color schemes and presentation methods based on the content explained in the meeting. I felt that their high level of content comprehension was also a mark of a professional.
Also, although it took us time to prepare the manuscript, they scheduled it according to our desired delivery date, and we were able to entrust the project with peace of mind in terms of project management as well."
