When it is found that there are major defects in the design, which will lead to major accidents, as a member of a team, I believe that by pointing out the defects and existing problems immediately, I can prevent them from being put into production and joining the market, which will cause greater losses. It is also more necessary to find ways to make up for the existing defects. Because a project requires a lot of time and money, it is difficult to re-establish the project, and it is still a project to be completed. It is a less costly way to find ways to make up for the design defects. As a whistleblower, whether it will be suppressed by the company comes from the company’s own choice of direction, at least the choice of the team is based on moral ethics.
