As our company primarily engages in the hardware business, we initially approached the project from a hardware design perspective, aiming to incorporate new hardware features. However, as user needs became more precise over time, we discovered that our new objectives are 'more flexible functionality' and 'greater intelligence.' After receiving the user survey results from the marketing team, we proceeded with the requirement definition and analysis of existing products. Additionally, we collected each product's Voice of the Customer (VOC) to make comparisons.
