This module reading pulls together key concepts and techniques from the Strategy Execution series into an integrated model - the levers of control. The four levers are: (1) belief systems, (2) boundary systems, (3) diagnostic control systems, and (4) interactive control systems. The module discusses how top managers use the levers of control to inspire commitment to the organization's purpose; stake out the territory for experimentation and competition; coordinate and monitor the execution of today's strategies; and stimulate and guide the search for strategies of the future. The power of this integrated approach to strategy implementation is illustrated in two contexts: the introduction of performance measurement and control systems over the life cycle of a growing business and the use of the levers by managers taking charge of a new business. 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.
