1.0.1.1 The Mandate: Single Source of Truth

The Handbookhandbook functionsexists asto eliminate variation and prevent the authoritative kernelcreation of the"shadow Dannie Operating System. If a process, policy,processes"—informal or specificationundocumented ismethods not explicitly documented within this repository, it is formally considered non-existent.

This "Handbook-First" protocol serves two specific engineering functions:

1. Error Elimination: It removes the noise of subjective interpretation.
2. Correction Authority: It authorizes any employee, regardless of tenure or rank, to correct a senior team member if their actions deviate from the documentation.

Operational changes must be committed to the Handbook via a merge request or update procedure before being implementeddeveloped on the factory floor.

The Definitive Authority

The handbook establishes procedural authority across all functional disciplines.

• Process Control: It contains the final, verified Standard Work Instructions (SWI) for all critical operations (torque sequencing, soldering profiles, cleaning).
• Technical Specification: It acts as the final reference for acceptable tolerances (e.g., IPC Class limits, acceptable solder void percentages) and measurement systems.
• Prohibition: No process, procedure, or quality standard may be implemented or used on the factory floor unless it is formally documented and resident within the current revision of this handbook.

Eliminating Ambiguity

When a procedural or technical dispute arises, the handbook provides the immediate and final resolution.

• The Final Arbiter: The document serves as the absolute arbiter during conflict resolution between departments (e.g., Quality vs. Manufacturing).
• Communication: It standardizes the technical language and process nomenclature used within the organization, minimizing errors caused by miscommunication.

0.1.2 Deviation and Process Fault

Any failure to follow the defined procedure is categorized as a Process Fault or Non-Conformance that must be logged and addressed.

1.1.2

Managing Deviations

• Mandate: Any deviation from the established procedure (e.g., using a non-standard component, omitting a quality check) is prohibited unless formally authorized by a temporary Manufacturing Engineering Deviation (MED) or a permanent Engineering Change Notice (ECN).
• Auditable Record: All deviations must be logged into the MES (Manufacturing Execution System) and linked to the unit's Serial Number (SN).
