Schedule Acceleration vs Productivity
Direct additional resources only at the verified schedule constraint; resolve material, information, and access bottlenecks before mobilising extra labour.

Regulations
Business Context
Projects commonly attempt to recover schedule by adding labor, overtime, shifts, or simultaneous work fronts. Beyond a certain point, congestion, fatigue, supervision limits, and coordination requirements can reduce productivity enough to offset the additional resources.
Green Field Industrial Projects TRIZ Resolution
Accelerate the constraint rather than the entire construction system. Identify limiting work fronts, materials, equipment, access, engineering information, and supervision, then increase resources only where additional capacity produces useful progress.
Applicable TRIZ Principles
Principle 1 – Segmentation focuses acceleration on schedule-critical activities.
Principle 10 – Prior Action removes constraints before additional resources are mobilized.
Principle 20 – Continuity of Useful Action reduces waiting and interruptions to increase productive time.
Expected Outcome
Faster schedule recovery
Higher field productivity
Better workforce utilization
Lower acceleration cost
Decision Indicators
Early indicators include:
Headcount increases faster than installed quantities.
Overtime produces declining output per labor hour.
Crews frequently wait for materials or information.
Additional shifts compete for the same work fronts.
Acceleration costs increase without equivalent schedule improvement.
