Enterprises and institutions need to evaluate their activity in order to determine the extent to which their goals have been achieved. One possible way to carry out this evaluation is to measure performance, for which organizations rely on metrics known as Key Performance Indicators (KPI). KPIs represent a set of measures focusing on those aspects of organizational performance that are the most critical for the current and future success of the organization and its ongoing projects. Thus the right KPIs can be used in order to make improvements to construction organizations and projects. The main point about identifying KPIs, is to find out the main characteristics and defenitions of them. Our research is intended to have a comprehensive study and review on available KPI defenitions provided by previous related and valid works and also identify the essential KPI characteristics. In order to identify the the essential characteristics for a KPI to be efficient and effective and also to have a comprehensive review on KPI defenitions, by searching the most related key words to the topic,133 articles were selected, which 22 of them were related to KPI definition and 11 article were about the characteristics of right KPIs. After studying the select articles completely, the same characteristics in different articles were combined together and recorded as a single characteristic with a specific number of repeats. By sorting the selected characteristic based on number of repeats in other researches and in a descending order, a completed list of essential characteristics for KPIs was provided. As a result of this research, a list of 51 characteristics for key performance indicators and by investigating all of the valid defenitions of KPI methodology, a comprehensive definition was provided. At last, for each identified KPI, a complete definition with a practical example from organizations or projects in the context of construction industry was mentioned. The outcomes of this research could be a base for identifying the right KPIs in different industries, especially construction industry.
