Improving a coffee machine can mean different things depending on what aspect of the machine needs improvement. One important factor to consider is the stickiness of the coffee machine. This refers to how likely it is for a customer to continue using the machine and to become loyal to the brand. In order to improve stickiness, the coffee machine should have a user-friendly design, be reliable, and have a range of high-quality coffee options. If I were in an elevator with the CEO of Nespresso and had two minutes to pitch an idea for improving their coffee machine, I would suggest that they consider adding a feature that allows customers to customize their coffee experience. This could be achieved through the use of a mobile app that connects to the machine and allows users to adjust the strength, temperature, and other factors of their coffee. This would not only improve the user experience, but also create a deeper sense of engagement and loyalty among customers. As a product manager, it is important to always be thinking about ways to improve the product and enhance the customer experience. This can involve gathering feedback from users, analyzing market trends, and collaborating with other departments within the company to ensure that the product is meeting the needs of both the business and the customer.
