1. I think that there is still a need, because if it is not a need, it can not solve the problem of pain points. It can be very difficult to sell this product if you don't buy it.
2. Frequency. If the product is used very infrequently, it will be difficult for users to form an impression and experience. Last year, many O2O home services were too infrequent, making it difficult for users to accept many services.
3. When designing product functions, I often make this mistake myself. For example, as listed in the last video of Tang Wenbin, it was originally a product at the front desk of the company. I wanted to give him a high score, but in the end I decided to give him a low score.
Good products, especially in the early days, should not have too many functions. Because you don't know what will happen to this market, you should highlight your important functions. If you can impress users, it will prove that we have succeeded in betting, and we can add things along the trend. Otherwise, the market has not been verified, we will make seventy or eighty functions. In the end, if you are unsuccessful, you will not know why the user likes or dislikes your product.
