01 — A seven-step interface
A practical generic chain is: regulatory baseline → client/architect requirement → system/product definition → technical data and quotation → procurement/logistics → installation/commissioning → maintenance and lifecycle. Each handover should preserve assumptions, constraints and responsibilities.
02 — Interface risks
Typical generic risks include ambiguous product interfaces, dimensional assumptions, incomplete installation data, documentation that sales can read but installers cannot use, mismatched commercial and technical identifiers, and maintenance requirements that appear too late.
03 — Why technical-commercial roles matter
The role is not to replace the engineer, installer, buyer or salesperson. It is to make the boundaries between them visible — translating enough context so that commercial decisions do not detach from technical reality.
04 — Working method
Use a traceable requirement register, controlled product-data fields, clear source references, change notes, installation constraints, ownership tags and a deliberate handover checklist. The goal is decision quality, not paperwork for its own sake.
05 — Confidentiality boundary
This framework is independently created and intentionally generic. It contains no employer drawings, customer projects, internal workflows or non-public specifications.
