Performance generally means the level of work. Effective resource use, productivity, efficiency, profitability or the realization level of similar organizational aims reflect the performance level of a business. Performance is also the level of a work finished or outputs achieved according to certain goals. Organizational performance is the skill for reaching the organization’s aims using the scarce resources in effective and efficient ways and the consequence of an output or work after a certain period of time. Organizational efficiency means reaching and achieving organizational goals. Organizational effectiveness indicates that how an organization satisfies the demands of various groups. Effectiveness means an evaluation of the usefulness of an organization’s work and how sources are used during this process and also the level of achieving the result that the organization aims to reach. We may summarize these three concepts which are very similar to each other as follows: Efficiency is the criterion for the capability of doing things right during the valuecreation process and effectiveness is the measure of realizing the plans made beforehand, while productivity means producing an output with the least possible input.  As also understood from the information given the definitions “Organizational efficiency means reaching and achieving organizational goals.”, “Organizational effectiveness indicates that how an organization satisfies the demands of various groups.” and “Productivity means producing an output with the least possible input.” are correct. The correct answer is “D”. The definitions in the options IV and V are not correct. Efficiency is the criterion for the capability of doing things right during the valuecreation process, while effectiveness is the measure of realizing the plans made beforehand.
