I think that in addition to scalability, modularity is also very important, ie the ability to add new parts to already existing parts of the project and that these parts fit well with each other. All designers know that if we develop a corporate identity, then it is based on several basic composite blocks that can be used to design different products. This is one type of modularity. Another type of modularity can be in the fact that a certain system is pre-laid in the company's logo, on the basis of which a logo for a subsidiary company can be developed and it will be clear to everyone that these two companies are related to each other. Of course, there are a lot of other types of modularity.
You're right, this is the subject of a new post =)
Well, for me it will be interesting!
