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
