This chapter presents practical guidelines regarding the application of the model for competitive international strategy. Guidance relates to general steps to develop a strategy, operationalization of the model components, and how to develop competitive international strategy based on the example of the COLT case. Management of a firm is advised to formulate a competitive international strategy following these principal steps: (1) specify the current competitive international strategy and lessons from the past; (2) formulate relevant strategy alternatives and pay attention to competition (focused or global standardization, focused or global responsiveness, or combinations?); and (3) choose a competitive international strategy. For the last step, it is important to evaluate to what extent the strategy relies on sustainable competitive advantages, consistency among items of the strategy, whether it is explicitly formulated, enabling communication within the firm and with stakeholders, and whether it is possible to adjust the strategy under the influence of competition.
