There are a lot of things that we associate with good design. Does the solution solve the problem? Does the product connect on an emotional level with the users? Does it consider different users and their needs? Is it beautiful? All of these things are reasons for some people to consider something good design. But some of them are disputable. Something might be beautiful to you, but not to me. Something might solve the problem, but solve it in a way that doesn’t really make me care about it.
So what is something that all of us would consider good design? One might say attention to detail, but that would be inaccurate. What we all should consider good design is intentional design. Good design is design where every detail was a conscious decision. From the packaging to the materials, everything was considered and everything is telling you the same story. That is the sort of design we should aim to do.
