Fit is important because discrete activities often affect one another. A sophisticated sales force, for example, confers a greater advantage when the company's product embodies premium technology and its marketing approach emphasizes customer assistance and support, A production line with high levels of model variety is more valuable when combined with an inventory and order processing system that minimizes the need for stocking finished goods, a sales process equipped to explain and encourage customization, and an advertising theme that stresses the benefits of product variations that meet a customer's special needs.
