Naming of subchapters which deal with same topic in different case
How should one select the titles for a thesis?


It is rather repetitive to use structures such as 

 4.1 Usage of Software-as-a-Service
 4.1.1 Usage of Software-as-a-Service at Company A
 4.1.2 Usage of Software-as-a-Service at Company B


I suggest something less repetitive, e.g., 

 4.1 Software-as-a-Service
 4.1.1 Case study: Company A
 4.1.2 Case study: Company B
