I mean - no. If you're coming to a completely new domain you have to decide what the important entities are, and what transformations you want to apply.

Neither data structures nor algorithms, but entities and tasks, from the user POV, one level up from any kind of implementation detail.

There's no point trying to do something if you have no idea what you're doing, or why.

When you know the what and why you can start worrying about the how.

Iff this is your 50th CRUD app you can probably skip this stage. But if it's green field development - no.

Sure context is important - and the important context you appear to have missed is the 5 rules aren't about building websites. It's about solving the kind of problems which are easy to state but hard to do (well) .

eg sort a list.
