This module reading describes the basics of building a successful strategy. Topics in this module include a discussion of the distinction between corporate and business strategy; how to conduct a SWOT analysis of market dynamics and internal capabilities; the use of the five forces analysis to understand customers, suppliers, products, and competitors; how to use this analysis to identify unique opportunities to create value for customers; and an overview of the four Ps of strategy implementation (strategy as perspective, position, plans, and patterns of action). The concepts introduced in this module provide the foundation for executing strategy effectively. While this module is designed to be used alone, it is part of the Strategy Execution series. Taken together, the series forms a complete course that teaches the latest techniques for using performance measurement and control systems to implement strategy. Modules 1 - 4 set out the foundations for strategy implementation. Modules 5 - 10 teach quantitative tools for performance measurement and control. Modules 11 - 15 illustrate the use of these techniques by managers to achieve profit goals and strategies. View the full Strategy Execution series at: hbsp.harvard.edu/strategy-execution.
