AB  - The Parade of Trades game demonstrates how variability that propagates across sequential trades degrades work flow reliability. Prior work pertaining to the use of takt to manage the Parade of Trades explores how planning for handoffs at a fixed beat can accommodate variability. It also shows where waiting occurs and capacity is lost, and how those influence each trade’s time on site and the total project duration. This paper builds on prior work related to the Parade of Trades by adding transfer batching to study how handoff sizing between trades relates to the production system’s performance. The study uses discrete-event simulation. Alternative model variants represent capacity variability and vary in transfer-batch sizes. Results show how transfer-batch sizing affects production system performance. Understanding these results can inform work structuring efforts, for example when developing a takt plan or when sizing capacity buffers and timing handoffs between trades.
