Reader questions
The newsroom receives steady mail about how briefs relate to tuition tracks, what we exclude on purpose, and how to cite us in procurement packets. The four entries below condense the most recent threads. We keep answers short enough for a hallway conversation yet precise enough for managers to forward without extra polish. When a topic needs diagrams, we link out to the relevant workshop page rather than duplicating lab assets here. Limitations matter as much as wins: if a question assumes a carrier promise we cannot verify, we say so plainly. Updates land here first, then migrate into syllabus sidebars during the next cohort freeze.
No. Articles compress field notes; cohort courses still carry the interactive SIP captures and mentor feedback loops.
