I'm looking for a noun that describes the process of "Designing / devising a concept". For example for a website: Means writing a general concept for the designer and developers, sketching wireframes, describing features and so.
- I'm unhappy with "Design" because I could be misunderstood with designing the actual graphic design
- I guess "conceptual design" isn't used widely
- and "conceptions" seems to be used in a more philosophical sense (e.g. conceptions of the world).
- In German we would use "Konzeption" or "Konzeptionierung" but "conceptualization" sounds weird to me.
Which noun would you suggest? Am I right with my interpretations of the listed options?
