Many artists work from indeterminate concepts, as opposed to a fixed plan (like mechanical or architectural drawings), so the thinking about the work as it is being made is constantly changing, all the way up until the work is finished, at which point the artist realizes, "That's what I was thinking and doing." Understanding the process usually comes in hindsight, and only matures after many years or decades. Sometimes making another version of it helps you to understand it better, or to fully put it to rest.
A thorough exploration of ideas usually involves taking into consideration every possible aspect to see if they augment or further clarify concepts or ramify into other ideas. Digital transformation is the perfect tool for this process, and I frequently use smartphone apps as "idea projectors".
