Parallel Engineering vs Interface Stability
Establish a formal interface register with defined ownership and maturity gates before authorising parallel discipline advancement.

Business Context
Parallel engineering allows multiple disciplines and packages to progress simultaneously, reducing overall duration. When dependent teams advance before interfaces stabilize, inconsistent assumptions can produce clashes, redesign, and configuration conflicts.
Green Field Industrial Projects TRIZ Resolution
Define and control critical interfaces separately from detailed engineering. Establish interface parameters, ownership, maturity status, and change rules so disciplines can progress concurrently without requiring every surrounding design element to be complete.
Applicable TRIZ Principles
Principle 1 – Segmentation separates interface definition from detailed discipline development.
Principle 10 – Prior Action establishes critical interface information before parallel work expands.
Principle 23 – Feedback rapidly communicates interface changes across affected disciplines.
Expected Outcome
Greater engineering concurrency
More stable interfaces
Reduced multidisciplinary rework
Shorter engineering schedules
Decision Indicators
Early indicators include:
Disciplines work from different design assumptions.
Interface changes generate repeated redesign.
Parallel work cannot begin until entire packages mature.
Interface ownership is unclear.
Coordination meetings focus repeatedly on unresolved boundaries.
