Which of management functions and skills do not appkly to the owner operator of sole proprietorship?

In a sole proprietorship, the owner-operator typically has limited management functions compared to larger organizations, as they often handle all aspects of the business themselves. Skills like strategic planning and complex financial management may be less relevant, given the smaller scale and simpler operations. Additionally, formal delegation of tasks and team management may not apply since the owner usually works independently or with minimal staff. Overall, the focus is more on operational and day-to-day management rather than advanced managerial functions.
