Glossary & Reference

Engineering Memory is the persistent, governed body of information through which System05 preserves engineering decisions, rationale, evidence, experience, failures, lessons, and lifecycle knowledge for future use.

Engineering Memory may include:

constitutional decisions and their rationale;

rejected alternatives;

requirements and change history;

test and prototype results;

manufacturing experience;

installation and inspection findings;

operational performance;

failures, nonconformities, and corrective actions;

regional adaptations;

maintenance and replacement outcomes.

Engineering Memory is more than archival storage. Its information shall remain identifiable, searchable, interpretable, versioned, and connected to the relevant entities and decisions.

The Digital Thread preserves lifecycle continuity for particular assets. The Engineering Knowledge Graph organizes semantic relationships. Engineering Memory preserves the accumulated evidence and reasoning needed to understand why the system exists in its current form.

Superseded information should remain available with its historical status rather than being silently deleted or presented as current guidance.
