Iterate or polish
The beautiful thing about focus is that is fuels decisions.
One of those decisions that focus fuels is between iteration or polish.
Both are important. Iteration helps someone discover the next step in development. Polish helps you story tell.
Often, people make the mistake of polishing a project iteration. It is a waste of time to make something, whose final destination is the trash bin, beautiful.
Other times the mistake is iterating on a polished project. That is when a team is more susceptible to feature creep. When it’s done, lock it and work on making it beautiful.
