Managers and executives do not typically become more effective as the result of a single training program or other intervention. Rather, development requires a range of ongoing and integrated activities. Drawn from CCL's "Tools for Developing Successful Executives" program, the six-step model described in this report provides the basics for designing a system that works. The steps, each covered in its own section, range from "Find and use organizational support for creating a process" to "Define and communicate the critical role of the manager." The sections contain commonsense information about the issues to consider when designing a development system plus numerous practical examples.
