The Parade Game illustrates the impact work flow variability has on the performance of construction trades and their successors. The game consists of simulating a construction process in which resources produced by one trade are prerequisite to work performed by the next trade. Production-level detail, describing resources being passed from one trade to the next, illustrates that throughput will be reduced, project completion delayed, and waste increased by variations in flow. The game shows that it is possible to reduce waste and shorten project duration by reducing the variability in work flow between trades. Basic production management concepts are thus applied to construction management. They highlight two shortcomings of using CPM for field-level planning: CPM makes modeling the dependence of ongoing activities between trades or with operations unwieldy and it does not explicitly represent variability. The Parade Game can be played in a classroom setting either by hand or using a computer. Computer simulation enables students to experiment with numerous alternatives in order to sharpen their intuition regarding variability, process throughput, buffers, productivity, and crew sizing. Managers interested in schedule compression will benefit from understanding work flow variability’s impact on succeeding trade performance.

  1. Introduction

    The Parade of Trades computer program simulates a dice game. The purpose of this game is to demonstrate the impact variability and dependence have in a construction environment where multiple trades follow each other in a linear sequence and work output by one trade is handed off to the next trade. The term "parade of trades" was coined by Gus Sestrup, a superintendent with Turner Construction.

    Greg Howell used the Parade of Trades Game at the 6th Annual Conference of the International Group for Lean Construction and the Lean Construction Institute has been using it at many of their workshops to demonstrate the effects of variability and dependence on work flow. The game was studied and documented in detail by Tommelein et al. (1998, 1999). They used Stroboscope (Martinez 1996) to simulate the Parade Game and collect statistics from the simulation. Alarcon and Ashley (1999) used @Risk (1997) to simulate a slightly modified dice game and analyzed its impact on project cost and schedule.

    The present program allows a user to simulate the Parade Game on a computer. By automatically keeping track of the number of rolls (executions per trade), the number of outputs passed to the next trade, and the number of outputs in each buffer between trades, the program helps the user understand what impact variability and dependence may have on work flow.
