why are analysis patterns not as popular as design patterns? i.e. template models to be tweaked per your particular domain modeling endeavor; "a kit of model fragments" (E.Evans);
they remove the need to reinvent the wheel e'ytime you need to model a domain. like a framework or library of concepts. like a react/angular/springboot for model concepts? not the best analogy but it'll do 🤓

think loose coupling and high cohesion of concepts before that of classes

you want #looseCoupling. standalone classes are a good thing. generally, the more of them you have in your design, the better it is in the sense it'll be easier it is to understand.
in designing your class, try to minimize the dependencies you have to other classes to zero if possible; keep these as primitives wherever it makes sense:
- field types
- method param types
- method return types
- types of local variables in methods
--- any other kinds?

when you first look at the model, it's a fluffy brown pillow
through the process of modeling you find out it's a hibernating grizzly
this is the importance of modeling i.e. constant refactoring of the comprehension of the domain via knowledge crunching #madquestionasking

you save yourself from building a solution based on the understanding of a pillow, when what the customer really needed was ... whatever you safely handle hibernating bears with?
a good understanding of what youre supposed to code for i.e. the model
1) captures core concepts of the subject matter
2) discards the irrelevant fluff
we achieve it thru asking a lot of questions, having many convos with subject matter experts
why? to produce better code
