The appropriateness of different styles of planning is based largely on how much the work is labor vs knowledge-work. Programming disproportionately ends up being knowledge work, because everyone is always working in a language, framework, scale, or business area that they don't understand.

After all, programming is a craft that can have things akin to "writer's block" (for instance, being stuck on a bug or design). It's more like writing the script than shooting the movie.
