This article proposes an alternative method for assessing the extent of family influence on any enterprise, enabling the measurement of the impact of family on outcomes such as success, failure, strategy, and operations. This proposed method, utilizing a standardized and valid instrument–the F-PEC–enables the assessment of family influence on a continuous scale rather than restrict its use as a categorical (e.g., yes/no) variable. The F-PEC comprises three subscales: power, experience, and culture. This article discusses these scales in detail.
