Takt Planning: a Reinterpretation of Adjustment Mechanisms From the Perspective of Slack

This paper offers a reinterpretation of takt planning through the lens of the slack concept, focusing on how adjustment mechanisms can address variability in construction projects. By analyzing 30 adjustment mechanisms identified in previous studies, the research evaluates how different types of slack (redundancy, flexibility, etc.) contribute to project stability. The study reveals that there is an intricate relationship between adjustment mechanisms in takt planning and the slack strategies, demonstrating that while takt planning is often criticized for its rigidity, it inherently integrates various forms of flexibility through slack strategies. The paper also highlights that there is a gap in addressing operational slack at the execution level, suggesting the need for deeper integration of micro-adjustments and day-to-day practices into formal takt planning frameworks.
