Overall, the 1999 data supported the hypothesized relationship directions and strength
of the hypothesized relationships. The other three data sets (1990, 1994, and 2008)
supported the directions of the hypothesized relationship directions and provided
faint to modest support of the strength of the model’s relationships. While this may be
due to the smaller sample sizes (1990 ¼ 59, 1994 ¼ 91 and 2008 ¼ 49) or fundamental
changes in the relationships is a matter for speculation. However, the authors conclude
that the agreement on the consistency of direction of the relationships in all four data
sets provides encouragement regarding the relationship of logistics strategy and
organization competitive responsiveness. The following section discusses relevance
and implications of these results.
