First, combining RBV and BTF enhances our understanding of the
drivers of firms' competitive behavior. This combined perspective emphasizes that external drivers (i.e., performance pressures) complement internal drivers (i.e., strategic capabilities) of speed of strategic action. While, poor performance creates pressures to take strategic initiatives, firms they are constrained by their own capabilities when choosing appropriate actions. As an analogy, strategic capabilities are like the arms for a battle (i.e., strategic actions) when the troop (i.e., the firm) confronts the threat of invasion (i.e., deteriorating performance); without the arms, the troop would be unable to fight an invader.
