I really like that categorization, but I think you've missed a step (or several): designing and implementing all the extra stuff needed to make it work, but aren't directly related to the problem.

For example, you have an idea for a cool and useful app and you want to put it on a website. You need to figure out hosting, you need to write some copy, you need to do some visual design.

Maybe 3a) Yak shaving?

There are various ways to take shortcuts. For hosting, you can use something super easy like GitHub Pages or Netlify or Cloudflare, or maybe piggyback off an existing site that's already deployed. For both copy and visual design, you can just ask Claude or Codex to do it -- but only if you don't mind having that standard vibe-coded look and feel, all glowing gradients and punchy, mic-dropping text.

Maybe you're including that under 5), ship/deploy/publish, but I read that as being more about scaling, marketing, and making things robust. Even before you reach that stage there's always a bunch of bullshit to work through before you can even reach 4), seeing the solution work for yourself.
