A layered product design framework organizes work across seven distinct decision areas, mapping how reality, problem space, and solution space relate. It works by separating foundational decisions from surface-level features to ensure structural alignment.

To orient a UX design session, use a seven-layer conceptual model to identify the correct investigative starting point. This ensures user needs and problem framing are validated before committing to interaction flows and surface-level visual decisions.

You need a conceptual model during product discovery and critique sessions when problem framing and solution structure require alignment. It surfaces missing or conflicting design decisions, preventing foundational gaps from becoming UX debt.

Yes, you can use the layered design approach for dependency checking between UX layers. The framework supports decision auditing across reality, problem space, and solution space to identify risky dependencies before they impact the interaction design.

The best way to identify foundational gaps in an interaction design strategy is to audit decisions across seven distinct layers. This checks foundational elements like user needs and conceptual models against interaction flows to surface missing requirements.

Conflicting design decisions across layers occur when problem framing and solution structures are misaligned. Applying a seven-layer orientation framework audits these dependencies, identifying where foundational user needs conflict with surface-level design choices.
