For a venture to be successful, from inception it must be structured with a focus on growth. To become a large, world-class company you must envision yourself in that manner. Beyond simply creating a strategy to enter the market, a successful corporate strategy should outline how a company will enter the market, dominate the market, and continue to grow.
As you keep an eye on growth, build out your resources with an understanding of what roles must be expanded should you be able to grow. This will entail a decision between expanding the roles of current employees or adding new resources to existing departments and tasks. Under a high growth scenario, it will be necessary to create an entire new set of tasks and departments within the organization.
