Feasibility checklists allow you to assess the viability of a new business concept. So far, you have been encouraged to think differently about your opportunity without financial barriers. The next exercise allows you to reflect on the suitability of your potential growth opportunity. First, consider Sabrina's process for evaluating the feasibility of her growth opportunity. This will give you a sense of how the process of checking the feasibility of an opportunity can give you confidence in approaching your vision for business growth. Sabrina: Every time we launch a new project, for example, take invisible hearing aids the first thing we need to do is a Feasibility Checklist and market research. The way we manage a project is very pragmatic and goal-oriented. After completing the Feasibility Checklist, we also evaluate the risks in order to minimize these and maximize positive market impact. This entire project management approach was learned during the 10,000 Women program. It taught me that everything could be treated as a project. The main problem concerning the Chinese hearing aid market is that the utility rate is very low. Out of 100 elderly people, only 2% would choose to wear a hearing aid. This is mainly due to the difference in awareness and how people value the severity of hearing disability. In the United States, the utility rate of hearing aids is estimated around 25% to 30%. Therefore, from the perspective of the utility rate, we see a big potential in the Chinese hearing aid market. We decided to specialize in invisible hearing aids, due to the fact that, typically, only 1-2% of elderly people choose to wear a hearing aid and only at a very late stage when their hearing is already very bad. They need a very powerful product. Due to the Chinese social mentality, elderly people do not want other people to notice that they have hearing issues. Therefore, after considering the Chinese situation, we decided to focus on the R&D of a powerful and invisible device. Another important issue is that the retail price of hearing aid devices in China is very high. For example, the price of an invisible device starts from RMB 16,800 and goes up to RMB 49,800. Therefore, in these circumstances, we aim to develop a product that is affordable to every senior citizen, and is half the price of the competitors. We have received good feedback from our customers. After three years of hard work, we have developed our star product, AcoSound invisible hearing aid, which is now the bestselling and leading invisible hearing aid brand in China. Now you have heard Sabrina's story, you can move on to the next exercise, where you will start to analyze the feasibility of your own opportunity.
