The many names of the rough vision sketch

Every deliberate artwork starts with a vision - and a sketch that captures it. I call it the "Proof of Concept", or POC for short(*). Different mediums have different names for the POC:

In writing of all sorts, the POC is called outline.
In film-making, the POC is called videoboard animatic.
In sculpting and architecture, the POC is called maquette.
In song-writing, the POC is called demo recording.
In game design, the POC is called mock-up level.
In web design, the POC is called wireframe.

All these names tell the same story, give the same advice, and represent the same tool: a quick sketch that captures our vision and enables us to test it, discuss it, judge it, and refer to it throughout our work.

(*) Help me get this right!

Is "Proof of Concept" really the best name for this tool? I'm not sure. I'm looking for a name that's catchy and easy to use, that isn't too identified with a specific medium, and that reflects what the vision sketch is - a quick yet clear version of the finished work. I've been thinking about several options, which one do you think works best? Also, feel free to suggest your own.

• The Proof of Concept
  
• The premake (this one is a good candidate, I think).
  
• The vision sketch
• The model
• The guide

Vision and Execution

And now, finally, for something "meaty": our very first practical tip. I'm still amazed at how many creative people fail to recognize this very simple pattern, and how often they fail to use it even when they DO notice it. It seems so obviously true, that I'm shocked at how long it took me to recognize it myself. I guess sometimes it's just too easy to miss the forest for the trees.

[From "The Art of Art": The art of the Process > Vision and Execution]

To put it very simply indeed, every work of [deliberate] art goes through two main stages: vision and execution. In the vision stage we collect information, raise different options, and finally sum it all up with a quick sketch of the finished work as we imagine it. Only after we had decided what the finished work is going to be like, we start executing the work itself. We could say that every [deliberate] creative work actually gets done twice: once when we form and sketch our vision, and again when we realize it.

The important thing about working with a vision is that it provides a clear framework for our efforts: we work until the result is close enough to our vision, and then we can stop. This frame of mind is fundamentally different from the open-ended "walk in the park" approach of casual art, in which we have no idea where we we're going and we only stop working when we're fed up or have ran out of time.

Deliberate work gets done twice: once when we form and sketch our vision, and again when we realize it.

Deliberate writing: sketch and execution.

Films are also made twice. Animatic vs. the finished result.

Sculpting is also done twice. Quick sketch vs. final work.

Computer games, AKA game level or maps, are also made twice: first the fully playable vision sketch, then the final level.
