can be translated as lead users. This refers to people who are qualified and motivated and act as opinion leaders for products in the launch phase. Lead
users are already involved in the innovation and development phases for new products and directly influence product innovation. Lead users can articulate their needs during the product innovation phase, as these are likely to be in line with the market.
Potential problems with a product can be identified early on in this way. Lead users are the first to work with the product during its lifetime and test its benefits. Later, the general users follow, whose number is considerably higher than that of the lead users.
