Parallel Work vs Coordination Complexity
Define explicit interface boundaries and controlled information release points before parallelising workstreams to prevent rework cascades.

Business Context
Performing design, procurement, fabrication, and construction activities in parallel can substantially shorten project duration. However, increasing concurrency creates more interfaces, dependencies, information exchanges, and opportunities for one activity to proceed using assumptions that later change.
Real Estate & Construction TRIZ Resolution
Parallelization should occur where interfaces can be clearly defined and controlled. Work can be divided into stable packages with explicit boundaries, while shared information is managed through coordinated release points. High-dependency activities can remain sequential where concurrency would create more risk than schedule benefit.
Applicable TRIZ Principles
Principle 1 – Segmentation creates work packages capable of progressing independently.
Principle 5 – Merging combines compatible activities where simultaneous execution creates value.
Principle 24 – Intermediary establishes controlled interfaces between concurrent workstreams.
Expected Outcome
Shorter overall duration
Controlled coordination requirements
Reduced interface errors
More reliable concurrent execution
Decision Indicators
Early indicators include:
Parallel activities repeatedly work from inconsistent information.
Interface changes create rework across multiple packages.
Coordination meetings increase without improving decision speed.
Schedule acceleration produces growing design and procurement conflicts.
Teams revert to fully sequential delivery because concurrency becomes unmanageable.
