Assessing Advantage: A Framework for Diagnosing Competitive Superiority
提出一个诊断竞争优势的框架，强调从客户和竞争者双视角监测优势来源与表现，帮助管理者避免短视，制定更有效的战略。
Strategy is about seeking new edges in a market while slowing the erosion of present advantages. Effective strategy moves are grounded in valid and insightful monitoring of the current competitive position coupled with evidence that reveals the skills and resources affording the most leverage on future cost and differentiation advantages. Too often the available measures and methods do not satisfy these requirements. Only a limited set of measures may be used, depending on whether the business starts with the market and uses a customer-focused approach or alternatively adopts a competitor-centered perspective. To overcome possible myopia, the evidence of advantage should illuminate the sources of advantage as well as the manifestations of superior customer value and cost superiority, and should be based on a balance of customer and competitor perspectives.
