Mobile development

Hello! How to start studying mobile development as a project manager? I am not interested in learning the language itself (there are plenty of materials on this topic), I am interested in general, what is the procedure for developing? For example, I know well how websites are developed. There is a back, there is a front, which specialist, what tasks he performs, which stack can be used where, and so on. Now I want to understand the same thing about mobile application development. Where to start learning how it all works?
