Inspired by Julie Zhuo’s article on Medium.com.
If you place your trust in a good process, then the end result will probably be pretty good. It’s that simple.
There different design processes, but the most important (arguably) part is the critique-solution exploration loop. And here I agree with Zhuo. The more we stay in that loop, the more refined and improved our design will be, because it will encapsulate more variations from multiple angles.
However, it must be noted (in the spirit of MVP) that this is not always possible, especially at the start of a product. Nevertheless, it is a good practice to return to a design and improve it. To think about the reasoning behind your design decisions and over time it will become a habit that reduces the loop, because you would have done it internally for the greater part. It is a skill. As I have mentioned in one of my other posts, being able to receive critique is one of the most important things, not only for a designer, but for anyone. Critique, or seeing your mistakes, is the key to improving them and thus growing.
