In the field of internal marketing, concern exists that advanced technology may be perceived as a negative target in employee attitudes. This is because new technology will completely change the processes that employees have accumulated and put their employment at risk. Therefore, to help employees understand the value of advanced technology, the technology concept is important. By targeting an organization’s big data analysis infrastructure, we verified a concept that is attractive to potential job-changers. A randomized controlled trial of 500 people in Japan revealed that potential job-changers are attracted to a workplace through the appeal of the presence of high-speed internal processes rather than high technical performance. This effect was more pronounced than concepts that promoted risk management such as personal information leaks, or that promoted management of business domain knowledge. The background to this is that close collaboration with business departments is essential for data scientists to function effectively. The factors that cause data science projects to fail are more prominent in the aspects of internal processes and organizational friction than in technical aspects. Having an internal environment that solves these problems is very attractive to employees. By analyzing employees’ needs and developing a concept, employees will have a positive attitude toward advanced technology.
