Organizational agility is a complex and multidimensional concept. One of the main challenges in researching organizational agility is its measurement. The variety and combination of attributes, characteristics, capabilities, and practices make the measurement of organizational agility level highly complicated and subjective. The purpose of this article is to explore the organizational agility level measurement methods and present a possible evaluation model.
