If non-parametric models, such as Data Envelopment Analysis, were ever considered as simple push-button technologies, this is impossible when many variables are available or when data have to be compiled from several sources. This paper introduces by the \u2018COOPER-framework\u2019 a comprehensive model for carrying out non-parametric projects. The framework consists of six interrelated phases: Concepts and objectives, On structuring data, Operational models, Performance comparison model, Evaluation, and Result and deployment. Each of the phases describes some necessary steps a researcher should examine for a well defined and repeatable analysis. The COOPER-framework provides for the novice analyst guidance, structure and advice for a sound non-parametric analysis. The more experienced analyst benefits from a check list such that important issues are not forgotten. In addition, by the use of a standardized framework non-parametric assessments will be more reliable, more repeatable, more manageable, faster and less costly. <!--{NETBLOG_EXPORT} N2U1YjRiYjUwYzQ3OGUwY2M2NTg0YTRhZjRhNzkzM2I= --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Latest version of COOPER-Framework is available at: https:\/\/doi.org\/10.1016\/j.ejor.2024.12.049 If using please cite: Mergoni, A.
