Characteristics of shallow models
Abstract, “top down” (not grounded)
Based on explicit, reified design elements (“boxology”)
Bridge/obviate need of full detail bycareful selection of modeled elements
Quality/believability/impression over fidelity
(may be) Domain-driven:broad(er) coverage at different resolutions (relevance)
Possibility of considering contingencies/external constraints (APIs, versatility, reusability, directability...)
