Firms operating in an international environment face a host of uncertaintie
s that make it difficult to meet deadlines reliably. To be reliable in an u
ncertain and changing environment, firms must be able to quickly respond to
changes. The ability to do this in a useful time frame is called agility.
Unfortunately, measures taken to increase agility often lead to increases i
n complexity which works against agility. We propose a theoretical construc
t linking elements of uncertainty with aspects of agility, pointing out the
two-edged nature of the requisite capabilities. We illustrate our points w
ith examples from five case studies.
