Mind Maps, Concept Maps, System Maps, Mental Models, and Concept Models: by Christina Wodtke
Designing an Elante?
Most often, you can design a pickup delivery experience directly on sketches, mockups, and code. Startups do that and it works fairly well - they rinse and repeat.
However, you cannot design a complex B2B product without some models to build on the system. So, you cannot design an Elante following the same process (and groundwork, planning, and focus) as you will do for an average-size shop in the market.
Christina Wodtke is my friend, and we have often discussed what she teaches extensively at the university level - models.
