The layered architecture, like MVC, is desired as it decouples software in layers that depends on their siblings or children and mostly because it can isolate domain logic from everything else (ui, application and infrastructure).
On the other side of the spectrum we have SmartUI software that mixes business rules in ui components. This sometimes is desired as DDD has its costs. But smart ui is only replaced later.

“When a design is based on a model that reflects the basic concerns of the users and the domain experts, the bones of the design can be revealed to the user to a greater extent than with other design approaches. Revealing the model gives the user more access to the potential of the software and yields consistent, predictable behavior”

“Play with the model as you talk about the system. Describe scenarios out loud using the elements sans interactions of the model, combining concepts in ways altered by the model. Find easier ways to say what you need to say, and then take those ideas back down to the diagrams and code.”

Seek precision in the model language by challenging it to be ubiquitous. Model out loud - listen to domain experts to talk about the domain and trim the edges

Cruntching knowledge is the first thing to do and the art of developing a shared vocabulary domain (or model objects) with experts and stakeholders.
