Why to design routines? The most improtant reason is reducing complexity. When you create a routine, you don't need to know the implementation. When you want to change another algorithm, you just modify this routine. Also, there are some other reasons to create routines:
(1). improve class readable.
(2). avoid duplicate code.
etc.
The cohesion conpect shows that class is well designed or not. Cohesion is at the routine level. So, we should design routines as cohesion as possible. The important is that one routine should has one function/operation.
