The Idea in Brief

The typical firm relies on one chief path to growth. Some companies develop most resources internally, others focus on licensing or joint venturing, and others are M&A specialists.

When firms fail at resource development, they tend to see it as an implementation problem. But research shows that the mode of acquisition is crucial to success. What’s more, companies acquiring resources in multiple ways are 46% more likely to survive the next five years than those relying mainly on alliances, 26% more likely than those focusing on M&A, and 12% more likely than those sticking with internal development. To select the right mode for the situation, ask three basic questions:

Are the resources you have relevant to the ones you want? If so, opt for internal development; if not, go outside the company.

How easy is it to agree with resource providers on the value of what they have to offer? You need a shared understanding of value to make a purchase contract work effectively. Otherwise, consider an alliance or a business acquisition.

How close a relationship do you need to have with your provider? If generating the resources you want requires the involvement of many people and units, M&A may be a better solution than a partnership.

Executing a new strategy nearly always involves acquiring new resources and capabilities. Since firms can’t possibly get everything they need through internal development, it seems reasonable in theory to expect that they’ll often turn to licensing agreements, alliances, and M&A as well.
