Electrical Deliverables and its Interdisciplinary Interfaces

2

Preface

Interdisciplinary interface engineering:

• A major engineering aspect for electrical discipline

• Requires appropriate coordination at appropriate time to avoid mishap during execution

stage

• Interface types

Indirect interface – Deliverables exchanged as input or output without any squad check

Direct interface – Deliverables going through squad check before furnished as official

input or output.

• Basis of Interface

DCI – Document Control Index

DDM – Document Distribution Matrix

Vendor Documents requiring squad check
