Millet's misjudgment of pen demand may have the following reasons:
1. Left the tablet market for too long, not familiar with the tablet market situation
2. Product managers lack research on tablet users' habits
3. Research and development of adaptation and industry chain solutions, from upstream to downstream preparation is insufficient
4. In the case of uncertain pen demand, out of stock is better than overstock
Out of stock can be reproduced, and if the initial stock is too much to form inventory is fatal. Now that the official knows the demand for pens, it has said that it will increase the production capacity of pens, and it is believed that the future supply progress will be eased over time.
