Implementation Approach Architect (Layer 8) FAQs

Question 1

What is Layer 8 in the SDD workflow?

Accepted Answer

Layer 8, or the IMPL artifact, is a stage in the Structured Design Document workflow that documents the implementation strategy, specifically identifying who is responsible, the delivery timeline, and the technical scope.

Question 2

What is the difference between REQ and IMPL artifacts?

Accepted Answer

REQ (Layer 7) defines atomic technical requirements, while IMPL (Layer 8) defines the strategy and logistics for how those requirements will be built and by whom.

Question 3

Does this skill require existing documentation?

Accepted Answer

Yes, it typically requires upstream artifacts from Layers 1-7 (such as BRD, PRD, ADR, and REQ) to ensure full traceability and provide the necessary context for implementation.

Question 4

Is the IMPL document mandatory for every project?

Accepted Answer

No, the IMPL layer is optional. It is highly recommended for complex projects or team-based environments, but can be skipped for simpler, solo tasks.

Question 5

How does doc-impl help with project risk management?

Accepted Answer

It includes a dedicated Risk Assessment section where developers must document potential implementation risks, their likelihood, impact, and specific mitigation strategies.
