"Vertical Integration and the Scope of the Firm
" Grant identifies several costs of vertical integration
stating
"Vertical integration is disadvantageous when the firm’s needs can be met by a competitive market of independent suppliers... [it] may involve a loss of flexibility... in responding to demand fluctuations and in developing new products and processes" (p. 268).

reducing its strategic flexibility" (Chapter 6
Section on Vertical Integration).
