Of Rice and Business Acumen
In his book “Traffic: Why We Drive the Way We Do (and What It Says About Us),” author Tom Vanderbilt uses a rice-pouring experiment to explain the science behind traffic jams. The experiment measures how long it takes one liter of rice, poured two separate times, to flow through a funnel and into a beaker. The first time, the rice is poured all at once; the second time, it is deployed in a “smooth, controlled flow.” Notably, the second pouring is nearly 30 percent faster – just 27 seconds.
Vanderbilt’s point is that smooth, controlled movement gets rice particles, and ultimately cars, through a bottleneck faster, because inflow never exceeds the capacity of the targeted funnel, beaker, or highway lane opening; the traveling bodies aren’t slowed down by the dynamics of too-close interaction or surrounding friction.
The same “smooth, controlled” deployment strategy can prevent organizational logjams as the economy recovers and businesses make investments in future growth. An overly aggressive, “all at once” expenditure on any business resource -- talent, technology, inventory, marketing – can result in overload that muddles productivity. As we make these future investments, Vanderbilt’s 30-percent statistic quantifies the value of ensuring that significant links in the business process chain are prepared to handle the volume.
