[Case Study] Television Program Production Company

[Case Study] Television Program Production Company

We will introduce an example of distributing a survey to areas that cannot be reached through street interviews!

We conducted a survey using "Surveyloid," which allows for easy online surveys for respondents across the country, to gather information beyond our immediate surroundings. Here, we present a case study from a television production company. The purpose was to distribute a survey to areas where street interviews cannot be conducted, and we aimed to conduct a survey on "favorite celebrities" to announce the differences in popularity and reasons for preference by region within the program. "We are required to create content within a very tight timeframe for television production, but this product allowed for quick data collection, giving us time to create our presentation, resulting in a satisfactory outcome," was the feedback we received. 【Survey Overview】 ■ Survey Purpose: Research on "favorite celebrities" ■ Survey Method: Internet survey ■ Target Participants: Ages 20-69 / Male and Female / Residents of the Tokyo metropolitan area (Saitama, Chiba, Tokyo, Kanagawa) ■ Number of Responses: 100 from each prefecture (total of 400 samples) *For more details, please refer to the related links or feel free to contact us.

Does the ES survey improve company sales? Introducing implementation methods and question templates.

Does the ES survey improve company sales? Introducing implementation methods and question templates.

We will also introduce the purpose of conducting the ES survey and the benefits gained from increasing employee satisfaction!

An ES survey (Employee Satisfaction Survey) is a survey that measures the satisfaction levels of employees regarding various aspects surrounding their work, such as job content, workplace environment, organizational culture, and treatment. As various work styles, including side jobs and freelancing, are on the rise, employee satisfaction with their companies is an important factor in reducing turnover rates and improving productivity. Therefore, many companies conduct ES surveys. By understanding their own challenges through the ES survey and implementing appropriate measures, companies can create a better working environment for employees, leading to improved performance. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

Multi-beam bathymetric survey to assess sediment accumulation and depth measurement at fishing ports.

Multi-beam bathymetric survey to assess sediment accumulation and depth measurement at fishing ports.

Visualizing sediment accumulation and usable water depth in fishing ports in a planar manner! Three-dimensional terrain data that can be utilized for dredging studies and maintenance management.

In fishing ports, the progression of sediment accumulation within the harbor and the assurance of usable water depth are important issues for daily operations and maintenance management. Especially in small-scale ports, localized sediment accumulation and changes in topography can directly impact operations. Our company utilizes its own multi-beam sonar equipment to acquire the seabed topography within fishing ports in a comprehensive manner. This data can be visualized and analyzed as three-dimensional topographic data. 【Main Issues We Can Address】 - Confirmation of sediment accumulation status within the fishing port - Understanding of usable water depth - Acquisition of current topography for dredging range considerations - Confirmation of sediment progression through comparative analysis of changes over time - Creation of basic materials for maintenance management planning We have a track record of fishing port-related work, particularly along the Tohoku coast, and we propose survey plans that take regional characteristics into account.
