Where as it is obviously important for everyone involved to know the users needs, I also think it is important to consider what the user does not want. If we are given a list of things to include and given some creative liberty, then there may come a product that includes something undesired by the user, but never expressed to the designer. For example, and I’m just making something up here, If they tell us that they need a new scaffold with certain qualities, but don’t mention it has to be entirely synthetic and cannot include animal collagen, then theres a potential for error. As easy as it is to include “unwanted qualities” in the initial requirements; if left unsaid, anything could set back the entire project.
