Effectiveness in business is measured by:

Effectiveness in business is fundamentally about how well an organization achieves its goals and objectives. When assessing effectiveness, the primary focus is on results and whether the business is reaching the outcomes it intended to achieve. Achieving set objectives indicates that the business is moving in the right direction and fulfilling its mission, which is crucial for long-term success.

Effectiveness captures the overall success of an organization in meeting its strategic goals, as opposed to measuring processes or resources alone. This definition aligns with performance indicators that organizations often use to assess their effectiveness, such as market share growth, profit margins, or successful product launches.

Other choices, while important aspects of business management, do not directly measure effectiveness in the same way. For example, employee turnover can indicate organizational health but does not necessarily reflect the achievement of set objectives. Customer satisfaction rates are valuable for assessing how well a business meets customer needs but also do not directly correlate with the achievement of internal goals. The efficiency of resource allocation focuses more on how resources are used rather than the overall success in meeting objectives. Hence, achieving set objectives is the clearest measure of effectiveness in a business context.
