Schedule Buffer vs Capital Efficiency
Concentrate schedule buffers on genuinely uncertain critical-path activities rather than distributing contingency uniformly to avoid inflating project duration and financing cost.

Business Context
Schedule buffers can protect completion dates against weather, supply disruption, productivity variation, and other uncertainties. However, excessive contingency can extend project duration, increase financing and overhead costs, delay revenue generation, and reduce capital efficiency.
Real Estate & Construction TRIZ Resolution
Schedule protection should be concentrated around uncertain or critical activities rather than distributed uniformly throughout the project. Risk-based buffers, alternative work fronts, early procurement, modular sequencing, and rapid recovery mechanisms can protect completion without embedding unnecessary time everywhere.
Applicable TRIZ Principles
Principle 3 – Local Quality places schedule protection where uncertainty has the greatest consequence.
Principle 11 – Beforehand Cushioning provides targeted contingency for credible disruption.
Principle 20 – Continuity of Useful Action prepares alternative work when critical activities become constrained.
Expected Outcome
Greater schedule resilience
Shorter unnecessary project duration
Lower financing exposure
Improved capital efficiency
Decision Indicators
Early indicators include:
Contingency is added uniformly to most activities.
Large schedule buffers remain unused.
Project duration substantially exceeds productive construction requirements.
Removing contingency immediately creates unacceptable completion risk.
Alternative recovery strategies are not developed because schedule float is available.
